Extended to include the 10-Gigabit Ethernet interface.

 
Usage Guidelines

The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 1 to 13, and valid values for the port number are from 1 to 48.

Hardware Layer 3 switching adjacency statistics are updated every 60 seconds.

The following information is contained in the show adjacency command:

  • Protocol interface.
  • Type of routing protocol that is configured on the interface.
  • Interface address.
  • Method of adjacency that was learned.
  • MAC address of the adjacent router.
  • Time left before the adjacency rolls out of the adjacency table. After it rolls out, a packet must use the same next hop to the destination.

12.2(40)SG

Support for WS-X4606-10GE-E Twin Gigabit converter introduced.

 
Usage Guidelines

When a TwinGig converter is enabled or disabled, the number and type of ports on the line card change dynamically. The terminology must reflect this behavior. In Cisco IOS, 10-Gigabit ports are named TenGigabit and 1-Gigabit ports are named Gigabit. Starting with Cisco IOS Release 12.2(40)SG, to avoid having ports named TenGigabit1/1 and Gigabit1/1, the 10-Gigabit and 1-Gigabit port numbers are independent. The WS-X4606-10GE-E module with six X2 ports are named TenGigabit<slot-num>/<1-6>, and the SFP ports are named Gigabit<slot-num>/<7-18>.

On Supervisor Engine 6-E, Supervisor Engine 6L-E, Catalyst 4900M, Catalyst 4948E, and Catalyst 4948E-F, the ports are connected to the switching engine through a stub ASIC. This stub ASIC imposes some limitations on the ports: Gigabit and 10-Gigabit ports cannot be mixed on a single stub ASIC; they must either be all 10-Gigabit (X2), or all Gigabit (TwinGig converter and SFP). The faceplates of X2 modules show this stub-port grouping, either with an actual physical grouping, or a box drawn around a grouping.

Examples

The following example shows to determine how the X2 holes on a module are grouped on a WS-X4606-10GE-E:

Switch# show hw-module module 1 port-group
Module Port-group Active Inactive

Usage Guidelines

The statistics are collected per VLAN for Layer 2 switched packets and Layer 3 switched packets. The statistics are available for both unicast and multicast. The Layer 3 switched packet counts are available for both the ingress and egress directions. The per-VLAN statistics are updated every 5 seconds.

In some cases, the duplex mode that is displayed by the show interfaces command is different than that displayed by the show running-config command. The duplex mode that is displayed in the show interfaces command is the actual duplex mode that the interface is running. The show interfaces command shows the operating mode for an interface, but the show running-config command shows the configured mode for an interface.

If you do not enter any keywords, all counters for all modules are displayed.

Line cards that support auto-MDIX configuration on their copper media ports include: WS-X4124-RJ45, WS-X4148-RJ with hardware revision 3.0 or later, and WS-X4232-GB-RJ with hardware revision 3.0 or later.

Modification

Cisco IOS XE 3.4.0SG and 15.1(2)SG

This command was introduced on the Catalyst 4500 series switch.

 
Usage Guidelines

Statistics are collected on a per-VLAN basis for Layer 2-switched packets and Layer 3-switched packets. Statistics are available for both unicast and multicast traffic. The Layer 3-switched packet counts are available for both ingress and egress directions. The per-VLAN statistics are updated every 5 seconds.

In some cases, you might see a difference in the duplex mode that is displayed between the show interfaces (virtual switch) command and the show running-config switch (virtual switch) command. In this case, the duplex mode that is displayed in the show interfaces (virtual switch) command is the actual duplex mode that the interface is running. The show interfaces (virtual switch) command shows the operating mode for an interface, while the show running-config switch (virtual switch) command shows the configured mode for an interface.

If you do not specify an interface, the information for all interfaces is displayed.

The output of the show interfaces GigabitEthernet command displays an extra 4 bytes for every packet that is sent or received. The extra 4 bytes are the Ethernet frame CRC in the input and output byte statistics.

The show interfaces counters command displays the number of all of the packets arriving and includes the number of packets that may be dropped by the interface due to the storm-control settings. To display the total number of dropped packets, you can enter the show interfaces counters storm-control command.

The show interfaces counters storm-control command displays the discard count and the level settings for each mode. The discard count is a total of all three modes.

If you do not enter any keywords, all counters for all modules are displayed.

If you do not specify an interface, the information for all interfaces is displayed.

When you enter the show interfaces interface counters etherchannel command, follow these guidelines:

  • If interface specifies a physical port, the command displays the message "Etherchannel not enabled on this interface."
  • If interface is omitted, the command displays the counters for all port channels (in the system) and for their associated physical ports.
  • If interface specifies a port channel, the command displays the counters for the port channel and all of the physical ports that are associated with it. In addition, when you enter the command specifying the primary aggregator in a Link Aggregation Control Protocol (LACP) port channel with multiple aggregators, the output includes the statistics for all of the aggregators in the port channels and for the ports that are associated with them.

note.gif

Noteblank.gif The value for the Optical Tx Power (in dBm) equals ten times log (Tx Power in mW). If the Tx Power value is 3 mW, then the Optical Tx Power value equals 10 * log (3), which equals 10 *.477 or 4.77 dBm. The Optical Rx Power value behaves similarly. If the Tx Power or the Rx Power is zero, then its dBm value is undefined and is shown as N/A (not applicable).


The following example shows how to display detailed diagnostic monitoring data, including calibrated values, alarm and warning thresholds, A2D readouts, and alarm and warning flags. The A2D readouts are reported separately in parentheses only if they differ from the calibrated values:

12.2(25)EW

Extended to include the 10-Gigabit Ethernet interface.

 
Usage Guidelines

The Cisco IOS software automatically enters a directly connected route in the routing table if the interface is usable. A usable interface is one through which the software can send and receive packets. If the software determines that an interface is not usable, it removes the directly connected routing entry from the routing table. Removing the entry allows the software to use dynamic routing protocols to determine backup routes to the network, if any.

If the interface can provide two-way communication, the line protocol is marked “up.” If the interface hardware is usable, the interface is marked “up.”

If you specify an optional interface type, you see information only on that specific interface.

If you specify no optional arguments, you see information on all the interfaces.

When an asynchronous interface is encapsulated with PPP or Serial Line Internet Protocol (SLIP), IP fast switching is enabled. The show ip interface command on an asynchronous interface that is encapsulated with PPP or SLIP displays a message indicating that IP fast switching is enabled.

Examples

The following example shows how to display the usability status for a specific VLAN:

Switch# show ip interface vlan 1

12.1(8a)EW

This command was introduced on the Catalyst 4500 series switch.

12.2(40)SG

Support for command introduced on the Supervisor Engine 6-E and Catalyst 4900M chassis.

 
Usage Guidelines

In the Supervisor Engine 6-E, Supervisor Engine 6L-E, Catalyst 4900M, Catalyst 4948E, and Catalyst 4948E-F, the output of the show ip mfib command does not display any hardware counters.

The MFIB table contains a set of IP multicast routes; each route in the MFIB table contains several flags that associate to the route.

The route flags indicate how a packet that matches a route is forwarded. For example, the IC flag on an MFIB route indicates that some process on the switch needs to receive a copy of the packet. These flags are associated with MFIB routes:

  • Internal Copy (IC) flag—Set on a route when a process on the switch needs to receive a copy of all packets matching the specified route.
  • Signaling (S) flag—Set on a route when a switch process needs notification that a packet matching the route is received. In the expected behavior, the protocol code updates the MFIB state in response to having received a packet on a signaling interface.
  • Connected (C) flag—When set on a route, the C flag has the same meaning as the S flag, except that the C flag indicates that only packets sent by directly connected hosts to the route should be signaled to a protocol process.

A route can also have a set of flags associated with one or more interfaces. For an (S,G) route, the flags on interface 1 indicate how the ingress packets should be treated and whether packets matching the route should be forwarded onto interface 1. These per-interface flags are associated with the MFIB routes:

  • Accepting (A)—Set on the RPF interface when a packet that arrives on the interface and that is marked as Accepting (A) is forwarded to all Forwarding (F) interfaces.
  • Forwarding (F)—Used with the A flag as described above. The set of forwarding interfaces together form a multicast olist or output interface list.
  • Signaling (S)—Set on an interface when a multicast routing protocol process in Cisco IOS needs to be notified of ingress packets on that interface.
  • Not Platform (NP) fast-switched—Used with the F flag. A forwarding interface is also marked as Not Platform fast-switched whenever that output interface cannot be fast-switched by the platform hardware and requires software forwarding.

Examples

The following example shows how to display all active MFIB routes:

Switch# show ip mfib

12.1(8a)EW

12.2(25)EW

Added support for the 10-Gigabit Ethernet interface.

 
Usage Guidelines

If you omit all the optional arguments and keywords, the show ip mroute command displays all the entries in the IP multicast routing table.

The show ip mroute active kbps command displays all the sources sending at a rate greater than or equal to kbps .

The multicast routing table is populated by creating source, group (S,G) entries from star, group (*,G) entries. The star refers to all source addresses, the “S” refers to a single source address, and the “G” refers to the destination multicast group address. In creating (S,G) entries, the software uses the best path to that destination group found in the unicast routing table (through Reverse Path Forwarding (RPF).

Examples

The following example shows how to display all the entries in the IP multicast routing table:

Switch# show ip mroute

Field
Description

Flags:

Information about the entry.

D - Dense

Entry is operating in dense mode.

S - Sparse

Entry is operating in sparse mode.

s - SSM Group

Entry is a member of an SSM group.

C - Connected

Member of the multicast group is present on the directly connected interface.

L - Local

Switch is a member of the multicast group.

P - Pruned

Route has been pruned. This information is retained in case a downstream member wants to join the source.

R - Rp-bit set

Status of the (S,G) entry; is the (S,G) entry pointing toward the RP. The R - Rp-bit set is typically a prune state along the shared tree for a particular source.

F - Register flag

Status of the software; indicates if the software is registered for a multicast source.

T - SPT-bit set

Status of the packets; indicates if the packets been received on the shortest path source tree.

J - Join SPT

For (*, G) entries, indicates that the rate of traffic flowing down the shared tree is exceeding the SPT-Threshold set for the group. (The default SPT-Threshold setting is 0 kbps.) When the J - Join SPT flag is set, the next (S,G) packet received down the shared tree triggers an (S,G) join in the direction of the source causing the switch to join the source tree.

For (S, G) entries, indicates that the entry was created because the SPT-Threshold for the group was exceeded. When the J - Join SPT flag is set for (S,G) entries, the switch monitors the traffic rate on the source tree and attempts to switch back to the shared tree for this source if the traffic rate on the source tree falls below the group’s SPT-Threshold for more than one minute.

The switch measures the traffic rate on the shared tree and compares the measured rate to the group’s SPT-Threshold once every second. If the traffic rate exceeds the SPT-Threshold, the J- Join SPT flag is set on the (*, G) entry until the next measurement of the traffic rate. The flag is cleared when the next packet arrives on the shared tree and a new measurement interval is started.

If the default SPT-Threshold value of 0 Kbps is used for the group, the J- Join SPT flag is always set on (*, G) entries and is never cleared. When the default SPT-Threshold value is used, the switch immediately switches to the shortest-path tree when traffic from a new source is received.

Outgoing interface flag:

Information about the outgoing entry.

H - Hardware switched

Entry is hardware switched.

Timer:

Uptime/Expires.

Interface state:

Interface, Next-Hop or VCD, State/Mode.

(*, 224.0.255.1)
(198.92.37.100/32, 224.0.255.1)

Entry in the IP multicast routing table. The entry consists of the IP address of the source switch followed by the IP address of the multicast group. An asterisk (*) in place of the source switch indicates all sources.

Entries in the first format are referred to as (*,G) or “star comma G” entries. Entries in the second format are referred to as (S,G) or “S comma G” entries. (*,G) entries are used to build (S,G) entries.

uptime

How long (in hours, minutes, and seconds) the entry has been in the IP multicast routing table.

expires

How long (in hours, minutes, and seconds) until the entry is removed from the IP multicast routing table on the outgoing interface.

RP

Address of the RP switch. For switches and access servers operating in sparse mode, this address is always 0.0.0.0.

flags:

Information about the entry.

Incoming interface

Expected interface for a multicast packet from the source. If the packet is not received on this interface, it is discarded.

RPF neighbor

IP address of the upstream switch to the source. “Tunneling” indicates that this switch is sending data to the RP encapsulated in Register packets. The hexadecimal number in parentheses indicates to which RP it is registering. Each bit indicates a different RP if multiple RPs per group are used.

DVMRP or Mroute

Status of whether the RPF information is obtained from the DVMRP routing table or the static mroutes configuration.

Outgoing interface list

Interfaces through which packets are forwarded. When the ip pim nbma - mode command is enabled on the interface, the IP address of the PIM neighbor is also displayed.

Ethernet0

Name and number of the outgoing interface.

Next hop or VCD

Next hop specifies downstream neighbor’s IP address. VCD specifies the virtual circuit descriptor number. VCD0 indicates that the group is using the static-map virtual circuit.

Forward/Dense

Status of the packets; indicates if they are they forwarded on the interface if there are no restrictions due to access lists or the TTL threshold. Following the slash (/), mode in which the interface is operating (dense or sparse).

Forward/Sparse

Sparse mode interface is in forward mode.

time/time
(uptime/expiration time)

Per interface, how long (in hours, minutes, and seconds) the entry has been in the IP multicast routing table. Following the slash (/), how long (in hours, minutes, and seconds) until the entry is removed from the IP multicast routing table.

This command was introduced on the Catalyst 4500 series switch.

Examples

These examples show how to display the IP source guard configuration and filters on a particular interface with the show ip verify source interface command:

  • This output appears when DHCP snooping is enabled on VLANs 10–20, interface fa6/1 has IP source filter mode that is configured as IP, and an existing IP address binding 10.0.0.1 is on VLAN 10:
Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------
fa6/1 ip active 10.0.0.1 10
fa6/1 ip active deny-all 11-20
 
note.gif

Noteblank.gif The second entry shows that a default PVACL (deny all IP traffic) is installed on the port for those snooping-enabled VLANs that do not have a valid IP source binding.


  • This output appears when you enter the show ip verify source interface fa6/2 command and DHCP snooping is enabled on VLANs 10–20, interface fa6/1 has IP source filter mode that is configured as IP, and there is an existing IP address binding 10.0.0.1 on VLAN 10:
Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------

--------- ----------- ----------- --------------- -------------- ---------
fa6/3 ip inactive-no-snooping-vlan
 
  • This output appears when you enter the show ip verify source interface fa6/4 command and the interface fa6/4 has an IP source filter mode that is configured as IP MAC and the existing IP MAC that binds 10.0.0.2/aaaa.bbbb.cccc on VLAN 10 and 11.0.0.1/aaaa.bbbb.cccd on VLAN 11:
Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------
fa6/4 ip-mac active 10.0.0.2 aaaa.bbbb.cccc 10
fa6/4 ip-mac active 11.0.0.1 aaaa.bbbb.cccd 11
fa6/4 ip-mac active deny-all deny-all 12-20
 
  • This output appears when you enter the show ip verify source interface fa6/5 command and the interface fa6/5 has IP source filter mode that is configured as IP MAC and existing IP MAC binding 10.0.0.3/aaaa.bbbb.ccce on VLAN 10, but port security is not enabled on fa6/5:
Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------
fa6/5 ip-mac active 10.0.0.3 permit-all 10
fa6/5 ip-mac active deny-all permit-all 11-20

Noteblank.gif Enable port security first because the DHCP security MAC filter cannot apply to the port or VLAN.


  • This output appears when you enter the show ip verify source interface fa6/6 command and the interface fa6/6 does not have IP source filter mode that is configured:
DHCP security is not configured on the interface fa6/6.

 

The following example shows how to display all the interfaces on the switch that have DHCP snooping security and IP Port Security tracking enabled with the show ip verify source command.

The output is an accumulation of per-interface show CLIs:

To display IP version 6 (IPv6) Multicast Listener Discovery (MLD) snooping querier-related information most recently received by the switch or the VLAN, use the show ipv6 mld snooping querier command.

show ipv6 mld snooping querier [ vlan vlan-id ]

 
Syntax Description

vlan vlan-id

(Optional) Specifiesa VLAN; the range is 1 to 1001 and 1006 to 4094.

12.2(40)SG

This command was introduced on the Catalyst 4500.

 
Usage Guidelines

Use the show ipv6 mld snooping querier command to display the MLD version and IPv6 address of a detected device that sends MLD query messages, which is also called a querier. A subnet can have multiple multicast switches but has only one MLD querier. The querier can be a Layer 3 switch.

The show ipv6 mld snooping querier command output also shows the VLAN and interface on which the querier was detected. If the querier is the switch, the output shows the Port field as Router. If the querier is a router, the output shows the port number on which the querier is learned in the Port field.

The output of the show ipv6 mld snoop querier vlan command displays the information received in response to a query message from an external or internal querier. It does not display user-configured VLAN values, such as the snooping robustness variable on the particular VLAN. This querier information is used only on the MASQ message that is sent by the switch. It does not override the user-configured robustness variable that is used for aging out a member that does not respond to query messages.

VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used in MLD snooping.

Examples

This is an example of output from the show ipv6 mld snooping querier command:

Switch> show ipv6 mld snooping querier
Vlan IP Address MLD Version Port
-------------------------------------------------------------
2 FE80::201:C9FF:FE40:6000 v1 Gi3/0/1
 

This is an example of output from the show ipv6 mld snooping querier vlan command:

Switch> show ipv6 mld snooping querier vlan 2
IP address : FE80::201:C9FF:FE40:6000
MLD version : v1

This command was introduced on the Catalyst 4500 series switch.

 
Usage Guidelines

Capability is a functionality that an ISSU client can support and is required to interoperate with peers.

When an ISSU-aware client establishes its session with the peer, an ISSU negotiation takes place. The ISSU infrastructure uses the registered information to negotiate the capabilities and the message version to be used during the session.

Examples

The following example shows how to display the ISSU capability types for the IP host ISSU client (clientid=2082):

Switch# show issu capability types 2082
Client_ID = 2082, Entity_ID = 1 :
Cap_Type = 0
Switch#
 

The following example shows how to display the ISSU capabilities entries for the IP host ISSU client (clientid=2082):

Switch# show issu capability entries 2082
Client_ID = 2082, Entity_ID = 1 :
Cap_Entry = 1 :

This command was introduced on the Catalyst 4500 series switch.

 
Usage Guidelines

Before attempting an ISSU, you should know the compatibility level between the old and the new Cisco IOS software versions on the active and the standby supervisor engines. ISSU will not work if the two versions are incompatible.

The compatibility matrix is available on Cisco.com so that you can also veiw in advance whether an upgrade can be performed with the ISSU process. The compatibility matrix during the ISSU process and later by entering the show issu comp-matrix command. To display information on the negotiation of the compatibility matrix data between two software versions on a given system, use the show issu comp-matrix negotiated command.

Compatibility matrix data is stored with each Cisco IOS software image that supports ISSU capability. To display stored compatibility matrix information, use the show issu comp-matrix stored command.

The compatibility matrix information are built-in any Cisco IOS ISSU image. The ISSU infrastructure performs a matrix lookup as soon as the communication with the standby supervisor engine is established. There are three possible results from the lookup operation:

  • Compatible—The Base-level system infrastructure and all optional HA-aware subsystems are compatible. In-service upgrade or downgrade between these versions will succeed with minimal service impact.
  • Base-Level Compatible—One or more of the optional HA-aware subsystems are not compatible. Although an in-service upgrade or downgrade between these versions will succeed, some subsystems will not be able to maintain their state during the switchover. Prior to attempting an in-service upgrade or downgrade, the impact of this on operation and service of the switch must be considered carefully.
  • Incompatible—A set of core system infrastructure must be able to execute in a stateful manner for SSO to function correctly. If any of these “required” features or subsystems is not compatible in two different Cisco IOS images, the two versions of the Cisco IOS images are declared “Incompatible”. This means that an in-service upgrade or downgrade between these versions is not possible. The systems operates in RPR mode during the period when the versions of Cisco IOS at the active and standby supervisor engines differ.

Examples

This example displays negotiated compatibility matrix information:

Usage Guidelines

Endpoint is an execution unit within a redundancy domain. There are only 2 endpoints on the Catalyst 4500 series switch redundant chassis: 1 and 2. The endpoints correspond to the slot numbers for the supervisor engine. The ISSU infrastructure communicates between these two endpoints to establish session and to perform session negotiation for ISSU clients.

Examples

The following example shows how to display the ISSU endpoints:

Switch# show issu endpoints
My_Unique_ID = 1/0x1, Client_Count = 46
 
This endpoint communicates with 1 peer endpoints :

12.2(31)SGA

This command was introduced on the Catalyst 4500 series switch.

 
Usage Guidelines

Messages are sync-data (also known as checkpoint data) sent between two endpoints.

When an ISSU-aware client establishes its session with a peer, an ISSU negotiation takes place. The ISSU infrastructure uses the registered information to negotiate the capabilities and the message version to be used during the session.

Examples

The following example shows how to display the message groups for Client_id 2082:

Switch#show issu message groups 2082
Client_ID = 2082, Entity_ID = 1 :
Message_Group = 1 :
Message_Type = 1, Version_Range = 1 ~ 2
Message_Type = 2, Version_Range = 1 ~ 2
Switch#
 

The following example shows how to display the message types for Client_id 2082:

Switch#show issu message types 2082
Client_ID = 2082, Entity_ID = 1 :
Message_Type = 1, Version_Range = 1 ~ 2
Message_Ver = 1, Message_Mtu = 12
Message_Ver = 2, Message_Mtu = 8
Message_Type = 2, Version_Range = 1 ~ 2
Message_Ver = 1, Message_Mtu = 32
Message_Ver = 2, Message_Mtu = 28

12.2(31)SGA

This command was introduced on the Catalyst 4500 series switch.

 
Usage Guidelines

Session is bidirectional and a reliable connection is established between two endpoints. Sync-data and negotiation messages are sent to the peer endpoint through a session. On a Catalyst 4500 series switch, each ISSU-aware client has a maximum of one session at each endpoint.

When an ISSU-aware client establishes its session with the peer, an ISSU negotiation takes place. The ISSU infrastructure uses the registered information to negotiate the capabilities and the message version to be used during the session.

Examples

The following example shows how to display the rollback-timer status:

Switch#show issu sessions 2072
Client_ID = 2072, Entity_ID = 1 :

12.2(25)EW

Enhanced the output of the show idprom interface command to include the 10-Gigabit Ethernet interface.

 
Usage Guidelines

In the Mod Sub-Module fields in the command output, the show module command displays the supervisor engine number but appends the uplink daughter card’s module type and information.

If the PoE consumed by the module is more than 50 W above the administratively allocated PoE, the “Status” displays as “PwrOver.” If the PoE consumed by the module is more than 50 W above the PoE module limit, the “Status” displays as “PwrFault.”

Examples

The following example shows how to display information for all the modules.

The following example shows the show module command output for a system with inadequate power for all installed modules. The system does not have enough power for Module 5; the “Status” displays it as “PwrDeny.”

This command was introduced on the Catalyst 4500 series switch.

 
Usage Guidelines

When the command is issued with no parameters, it displays the details of all the capture points. When specified with a capture point name and no other parameters, it displays the details of the specific capture point name. With the parameter keyword, the command reconstructs the commands that describe the capture point and displays them.

The buffer option displays the packets from the capture buffer. This option is applicable only if the capture point directs the captured packets to the buffer. The packets can be decoded and displayed in either the brief, detailed, or dump mode. The default mode is brief.

If you enter the command without keywords, the output includes the administrative and operational status of all secure ports on the switch.

If you enter the interface-id value or port-channel-interface value, the show port-security command displays port security settings for the interface.

If you enter the address keyword, the show port-security address command displays the secure MAC addresses for all interfaces and the aging information for each secure address.

If you enter the interface-id value and the address keyword, the show port-security address interface command displays all the MAC addresses for the interface with aging information for each secure address. You can also use this command to display all the MAC addresses for an interface even if you have not enabled port security on it.

Sticky MAC addresses are addresses that persist across switch reboots and link flaps.

12.1(8a)EW

This command was introduced on the Catalyst 4500 series switch.

12.2(52)SG

Support to display detailed PoE consumption information on an interface/module.

 
Usage Guidelines

If a powered device is connected to an interface with external power, the switch does not recognize the powered device. The Device column in the output of the show power inline command displays as unknown.

If your port is not capable of supporting PoE, you will receive this message:

Power over Ethernet not supported on interface Admin
 

The show power inline interface | module command displays the amount of power that is used to operate a Cisco IP Phone. To view the amount of power requested, use the show cdp neighbors command.

Because FPGAs and other hardware components on the WS-X4548-RJ45V+ and WS-X4648-RJ45V+E modules consume PoE, the operating PoE consumption for an 802.3af-compliant module can be nonzero when there are no powered devices attached to the module. The operating PoE can vary by as much as 20 W because of fluctuations in the PoE that is consumed by the hardware components.

Examples

The following example shows how to display information about the general power supply:

Switch# show power

Command
Description

Enters the redundancy configuration mode.

redundancy force-switchover

Forces a switchover from the active to the standby supervisor engine.

show redundancy config-sync

To display an ISSU config-sync failure or the ignored mismatched command list (MCL), if any, use the show redundancy config-sync command.

show redundancy config-sync { failures | ignored } { bem | mcl | prc }

show redundancy config-sync ignored failures mcl

 
Syntax Description

failures

Displays MCL entries or BEM/PRC failures.

ignored

Displays the ignored MCL entries.

bem

(Deprecated)

mcl

Displays commands that exist in the active supervisor engine’s running configuration, but are not supported by the image on the standby supervisor engine.

prc

Displays a Parser Return Code (PRC) failure and forces the system to operate in RPR mode provided there is a mismatch in the return code for a command execution at the active and standby supervisor engine.

Modification

12.2(31)SGA

This command was introduced on the Catalyst 4500 series switch.

12.2(44)SG

Updated command syntax from issu config-sync to redundancy config-sync.

 
Usage Guidelines

When two versions of Cisco IOS images are involved, the command sets supported by two images might differ. If any of those mismatched commands are executed on the active supervisor engine, the standby supervisor engine might not recognize those commands. This causes a config mismatch condition. If the syntax check for the command fails on standby supervisor engine during a bulk sync, the command is moved into the MCL and the standby supervisor engine is reset. To display all the mismatched commands, use the show redundancy config-sync failures mcl command.

To clean the MCL, follow these steps:


Step 1blank.gif Remove all mismatched commands from the active supervisor engines’ running configuration.

Step 2blank.gif Revalidate the MCL with a modified running configuration using the
redundancy config-sync validate mismatched-commands command.

Step 3blank.gif Reload the standby supervisor engine.


 

Alternatively, you could ignore the MCL by following these steps:


Step 1blank.gif Enter the redundancy config-sync ignore mismatched-commands command.

Step 2blank.gif Reload the standby supervisor engine; the system transitions to SSO mode.

note.gif

Noteblank.gif If you ignore the mismatched commands, the out-of-sync configuration at the active supervisor engine and the standby supervisor engine still exists.


Step 3blank.gif You can verify the ignored MCL with the show redundancy config-sync ignored mcl command.


 

Each command sets a return code in the action function that implements the command. This return code indicates whether or not the command successfully executes. The active supervisor engine maintains the PRC after executing a command. The standby supervisor engine executes the command and sends PRC back to the active supervisor engine. PRC failure occurs if these two PRCs do not match. If a PRC error occurs at the standby supervisor engine either during bulk sync or LBL sync, the standby supervisor engine is reset. To display all PRC failures, use the show redundancy config-sync failures prc command.

To display best effort method (BEM) errors, use the show redundancy config-sync failures bem command.

Examples

The following example shows how to display the ISSU BEM failures:

Switch# show redundancy config-sync failures bem
BEM Failed Command List
-----------------------

12.1(8a)EW

This command was introduced on the Catalyst 4500 series switch.

 
Usage Guidelines

In some cases, you might see a difference in the duplex mode displayed when you enter the show interfaces command and the show running-config command. If you do see a difference, the duplex mode displayed in the show interfaces command is the actual duplex mode that the interface is running. The show interfaces command shows the operating mode for an interface, while the show running-config command shows the configured mode for an interface.

The show running-config command output for an interface may display a duplex mode configuration but no configuration for the speed. When no speed is displayed in the output, it indicates that the interface speed is configured to be auto and that the duplex mode shown becomes the operational setting once the speed is configured to something other than auto. With this configuration, it is possible that the operating duplex mode for that interface does not match the duplex mode shown with the show running-config command.

Examples

The following example shows how to display the module and status configuration for all modules:

Switch# show running-config
03:23:36:%SYS-5-CONFIG_I:Configured from console by consolesh runn
Building configuration...

Usage Guidelines

The MTU_Mismatch column in the command output indicates whether all the ports in the VLAN have the same MTU. When “yes” is displayed in the MTU_Mismatch column, it means that the VLAN has a port with different MTUs, and packets might be dropped that are switched from a port with a larger MTU to a port with a smaller MTU. If the VLAN does not have an SVI, the hyphen (-) symbol is displayed in the SVI_MTU column.

For a VLAN, if the MTU-Mismatch column displays “yes,” the names of the port with the MinMTU and the port with the MaxMTU are displayed. For a VLAN, if the SVI_MTU is bigger than the MinMTU, “TooBig” is displayed after the SVI_MTU.

Examples

This is an example of output from the show vlan mtu command:

Switch# show vlan mtu
