Usage Guidelines

Bundle interface traffic is distributed over the various member links of a bundle according to a hash function. The bundle-hash command allows you to determine which bundle member link will carry a particular flow of traffic.

You can use the bundle-hash command to get these information:

  • Which members are used for a specified source/destination address pair, such as 10.10.10.1 20.20.20.1

  • The destination IP address for a specified source IP address on a specified member.

  • The load balancing distribution–how many times the members of a bundle are used for a specified range of IP addresses.

The bundle-hash command does not display all possible IP addresses in an entire series. It stops displaying addresses after all the addresses for all the members of the bundle have been displayed once.

The bundle-hash command is not applicable to multicast traffic and only applicable to unicast traffic.

The bundle-hash command invokes a utility that initially prompts you to select some options. Based on the options you select, the utility prompts you more options to select. The initial options to select are as follows:

  • L3/3-tuple or L4/7-tuple

  • Single pair or Range

  • IPv4 or IPv6

The bundle-hash command utility prompts you for these options as follows:

  • Specify load-balance configuration (L3/3-tuple or L4/7-tuple) (L3,L4):

  • Single SA/DA pair (IPv4,IPv6) or range (IPv4 only): S/R [S]:

  • Enter bundle type IP V4 (1) or IP V6 (2):

  • Enter source IP V4 address:

  • Enter destination IP V4 address:

  • Compute destination address set for all members? [y/n]:

  • Enter subnet prefix for destination address set:

  • Enter bundle IP V4 address [10.10.10.10]:

You may also be prompted to make further option choices depending on your selections.

You can use the show bundle command to get IP address information.

The following table provides a general summary of the options and the information you need to provide for each selected option. The actual information that you need to provide depends on the selections you make and may vary from the information provided.

bundle id

To add a port to an aggregated interface (or bundle), enter the bundle id command in interface configuration mode. To remove a port from the bundle, use the no form of the command.

bundle id bundle-id [mode {active | on | passive}]

Syntax Description

bundle-id

Number of the bundle (from 1 to 65535) on which you want to add a port.

mode

(Optional) Specifies the mode of operation, as follows:

  • active —Use the mode active keywords to run Link Aggregation Control Protocol (LACP) in active mode over the port. When you specify active , the port joins the bundle and is activated if LACP determines that it is compatible.
  • on —Use the mode on keywords to configure an Etherchannel link over the port (no LACP running over the port).
  • passive —Use the mode passive keywords to run LACP in passive mode over the port. When you specify passive , LACP packets are sent only if the other end of the link is using active LACP. The link joins the bundle and is activated if LACP packets are exchanged and the port is compatible.

Command Default

The default setting is mode on.

Usage Guidelines

If you enter the bundle id command and specify a port that is already bound to a bundle, the port unbinds from the original bundle and becomes attached to the new bundle. If the bundle numbers are the same, then the port does not unbind, but the mode changes to mode you specified with the bundle id command.

This example shows how to add an active LACP port onto an aggregated interface (or bundle):


RP/0/RP0/CPU0:router(config)# interface HundredGigabitEthernet 0/6/5/7
RP/0/RP0/CPU0:router(config-if)# bundle id 5 mode active
   

bundle maximum-active links

To designate one active link and one link in standby mode that can take over immediately for a bundle if the active link fails, use the bundle maximum-active links command in interface configuration mode. To return to the default maximum active links value, use the no form of this command.

bundle maximum-active links links [hot-standby]

Syntax Description

links

Number of active links you want to bring up in the specified bundle, up to the maximum supported on the platform. The range is 1 to 64.

hot-standby

Modifies some default timeouts, such as wait-while timer and suppress-flaps, to avoid bundle-level flaps when the highest priority link fails or recovers.

Command Default

No default behavior or values

Command Modes

Interface configuration

Command History

Release

Modification

Release 7.0.12

This command was introduced.

Usage Guidelines

Misconfiguration or inconsistent configuration with a remote side can be causing traffic loss even though the bundle is up. We recommend that you use LACP protocol to better protect against the misconfiguration.

If the bundle maximum-active links command is issued, then only the highest-priority link within the bundle is active . The priority is based on the value from the bundle port-priority command, where a lower value is a higher priority. Therefore, we recommend that you configure a higher priority on the link that you want to be the active link.

  • Another Cisco IOS XR device using the same option.
  • Another device using an IEEE standard-based switchover. (Cisco does not recommend using this option because unexpected behavior, such as the peer sending traffic on the standby link, can occur.)

When you configure the hot-standby keyword, if the partner device is not XR, you may have to further modify the timeouts. Use the commands that are used for refining the timeouts on the partner device as well. For best performance, do not configure with bundle-maximum-active links command on the partner device.

The bundle maximum-active links hot-standby command can be configured at both ends. However, this will impact the switchover times.

lacp cisco enable

To enable use of Cisco-specific TLVs in addition to standard TLVs for negotiating and exchanging LACP information on link bundles, use the lacp cisco enable command in interface configuration mode. To return to the default, use the no form of the command.

lacp cisco enable [link-order signaled]

Syntax Description

link-order signaled

(Optional) Includes link order numbering as part of the LACP processing.

Command History

Release

Modification

Release 7.0.12

This command was introduced.

Usage Guidelines

The lacp cisco enable link-order signaled command is required on bundle interfaces supporting deployment of Multi-Gigabit Service Control Point (MGSCP), and must be configured symmetrically on both the access and core bundle. When link order signaling is enabled, then only one set of Link Ordering Numbers (LONs) are used for the bundle, and LACP processing of LONs is enabled for load balancing tables.

The LONs from the highest priority LACP system take precedence. Where both systems have the same LACP system ID (for example, with MGSCP where both ends of the bundle terminate on the same device), the LONs from the bundle interface with the numerically lowest bundle ID take precedence.

When lacp cisco enable command is configured without link order signaling, then links are assigned ordering numbers as they become active and keep them until the link goes inactive. The numbers are exchanged using LACP, but they are not used.

{lacp packet-capture [bundle-ether bundle-id] [hundredgigabitethernet interface-path-id] [tengige interface-path-id] clear | stop}

Syntax Description

bundle-ether

Ethernet bundle interface specified by bundle-id .

TenGigE

Ten Gigabit Ethernet interface specified by interface-path-id .

interface-path-id

Physical interface or virtual interface.

Note

 

Use the show interfaces command to see a list of all interfaces currently configured on the router.

For more information about the syntax for the router, use the question mark (? ) online help function.

bundle-id

Number specifying the bundle interface. The range is 1 to 65535.

number-of-packets

Number of packets to capture.

clear

Clears all currently captured packets.

stop

Stops capturing packets.

Command Default

The default (no parameters) executes globally for all interfaces on the line card.

Command Modes

XR EXEC mode

Command History

Release

Modification

Release 7.0.12

This command was introduced.

Usage Guidelines

The lacp packet-capture command captures transmitted and received LACP packets on a single bundle member interface. The contents of these packets can then be displayed by the show lacp packet-capture command. If the lacp packet-capture command is not issued, the show lacp packet-capture command does not display any information.

The lacp packet-capture command continues capturing LACP packets until the stop keyword is issued for that port or that bundle. Captured packets are stored and continue to be displayed until the clear keyword is issued for that port or that bundle.

LACP packets can only be captured for one port on a line card at a time. Starting a packet capture on a port implicitly stops and clears all packet-captures on all other ports on that line card.

To stop capturing LACP packets before the specified number of packets have been captured, issue the stop keyword.

If stop is specified for a single interface, packet capturing is stopped only on that interface.

If stop is specified for a bundle interface, packet capturing is stopped on all members of that bundle.

If stop is specified globally (the default - no parameters), packet capturing is stopped on all bundle interfaces on the router.

To clear all captured LACP packets that are stored for an interface, issue the clear keyword.

If clear is specified for a single interface, packets are cleared only on that interface.

If clear is specified for a bundle interface, packets are cleared on all members of that bundle.

If clear is specified globally (the default - no parameters), packets are cleared on all bundle interfaces on the router.

lacp period short

To enable a short period time interval for the transmission and reception of Link Aggregation Control Protocol (LACP) packets, use the lacp period short command in interface configuration mode. To return to the default short period, use the no form of this command.

lacp period short [receive interval] [transmit interval]

Syntax Description

receive interval

Time interval (in milliseconds) for receiving LACP packets when LACP short period is enabled. The range is 100 to 1000 and must be multiples of 100, such as 100, 200, 300, and so on.

transmit interval

Time interval (in milliseconds) for transmitting LACP packets when LACP short period is enabled. The range is 100 to 1000 and must be multiples of 100, such as 100, 200, 300, and so on.

Command Default

The default is 1000.

Command Modes

Interface configuration

Command History

Release

Modification

Release 7.0.12

This command was introduced.

Usage Guidelines

When you configure a custom LACP short period transmit interval at one end of a link, you must configure the same time period for the receive interval at the other end of the link.


Note


You must always configure the transmit interval at both ends of the connection before you configure the receive interval at either end of the connection. Failure to configure the transmit interval at both ends first results in route flapping (a route going up and down continuously). When you remove a custom LACP short period, you must do it in reverse order. You must remove the receive intervals first and then the transmit intervals.

Note


Starting with Cisco IOS XR Software Release 7.1.1, the lacp period short receive and lacp period short transmit commands are deprecated. Use the lacp period <time in milliseconds> command to configure LACP receive and transmit time. Before using this command, you must first execute lacp cisco enable command in the bundle interface mode. Without lacp cisco enable command, the members may still transmit at the standard interval of 1 second.

Minimum active links / bandwidth:

Displays the following information in the format

x / y kbps, with the following values:

  • x—Minimum number of active links (from 1 to the maximum number of links supported on the bundle) that are required for the bundle to be operative.

  • y—Minimum total bandwidth on active links (in kbps) that is required for the bundle to be operative.

  • (partner)—Shows that the peer system's value is in use.

Maximum active links:

Maximum number of links (from 1 to the maximum supported on a bundle) that can be active on the bundle.

Wait-while timer:

Amount of time (in milliseconds) that the system allows for the Link Aggregation Control Protocol (LACP) to negotiate on a "working"link, before moving a "protect"or backup link to Standby state.

Load balancing:

Type of load balancing in use on the bundle, with the following possible values:

  • Default—The default load balancing method for the system is used on the bundle, and the load balancing sub-fields are not displayed.

  • No value—Another load balancing method is in use on the bundle, with information shown in the related sub-fields of the display.

LACP:

Displays whether or not Link Aggregation Control Protocol (LACP) is active on the bundle, with the following possible values:

  • Operational—All required configuration has been committed and LACP is in use on active members.

  • Not operational—LACP is not working because some mandatory configuration is missing on the bundle or on the active members of the bundle.

  • Not configured—None of the mandatory configuration for LACP has been committed on the bundle, and the LACP sub-fields are not displayed.

Flap suppression timer:

Displays the status of the flap suppression timer, with the following possible values:

  • Off—The flap suppression timer is not configured using the lacp switchover suppress-flaps command.

  • x ms—Amount of time allowed (in milliseconds) for standby links to activate after a working link fails, before putting the link in Down state.

Cisco extensions:

Displays whether or not the Cisco-specific TLVs for LACP are enabled. The possible values are "Enabled" and "Disabled".

Non-revertive:

Displays whether non-revertive behavior for the bundle interface is enabled or not. The possible values are "Enabled" and "Disabled".

mLACP:

Displays whether or not the bundle is operating using Multichassis Link Aggregation (MC-LAG), with the following possible values:

  • Operational—All required configuration has been committed for MC-LAG and mLACP is in use on the bundle.

  • Not operational—mLACP is not working because some mandatory configuration for MC-LAG is missing on the bundle or on the active members of the bundle.

  • Not configured—None of the mandatory configuration for MC-LAG has been committed on the bundle, and the mLACP sub-fields are not displayed.

ICCP group:

Number of the Interchassis Communication Protocol group (if configured) in which the bundle participates. Otherwise, "Not configured" is displayed.

Role

ICCP redundancy role of the local device for this mLACP bundle, with the following possible values:

  • Standby—Bundle is a backup locally.

Foreign links <active/configured>:

The number of links on the remote device in the format x / y , with the following values:

  • x—Number of links in Active state on the remote bundle.

  • y—Total number of links configured on the remote bundle.

Switchover type:

Method of performing an mLACP switchover on the bundle with the following possible values:

  • Brute force— Trigger the failover by marking member(s) as Not Aggregatable instead of using dynamic priority management. This is the only possible method of control when the dual-homed device (DHD) is the higher-priority system. Only applies to mLACP bundles.

  • Non-revertive—This is the default. Dynamic priority management is used, where the bundle does not fail back to the originally active point of attachment (PoA) except when a subsequent failure occurs.

  • Revertive—Dynamic priority management is used, but the higher-priority device (based on the configured port priorities for the bundle) is always Active unless it has encountered a failure. This means that if a failure is encountered triggering a switchover, once the failure condition is cleared the initially-active links become active again.

  • The switchover type can be changed from the default behavior using the mlacp switchover type command,

Recovery delay:

Number of seconds (s) to delay becoming the active mLACP device after recovering from a failure, using the mlacp switchover recovery delay command. "None" is displayed when the mlacp switchover recovery delay command is not configured.

Maximize threshold:

Threshold value below which mLACP switchovers are triggered to allow the bundle to reach the configured maximum number of active links or bandwidth (using the mlacp switchover maximize command), with the following possible values:

  • x links—Number of active links used as the maximum threshold target to be maintained as a trigger for an mLACP switchover on a bundle.

  • y kbps—Bandwidth in kilobits per second used as the target threshold to be maintained as a trigger for an mLACP switchover on a bundle.

  • Not configured—The mlacp switchover maximize command is not configured. mLACP switchovers are based on the minimum active links or bandwidth for the bundle.

IPv4 BFD:

Displays whether or not IPv4-based bidirectional forwarding (BFD) is operating on the bundle interface, with the following possible values:

  • Operational—All required configuration has been committed for IPv4 BFD, and it is in use on the bundle.

  • Not operational—IPv4 BFD is not working because some mandatory configuration is missing on the bundle or on the active members of the bundle.

  • Not configured—None of the mandatory configuration for IPv4 BFD has been committed on the bundle, and the BFD sub-fields are not displayed.

State:

When BFD is enabled, displays the state of BFD sessions on the bundle from the sessions running on bundle members that is communicated to interested protocols, with the following possible values:

  • Down—The configured minimim threshold for active links or bandwidth for BFD bundle members is not available so BFD sessions are down.

  • Off—BFD is not configured on bundle members.

  • Up—BFD sessions on bundle members are up because the minimum threshold for the number of active links or bandwidth is met.

Fast detect:

Displays whether or not BFD fast detection is configured on the bundle, with the following possible values:

  • Enabled—Thebfd fast-detect command is configured on the bundle.

  • Disabled—The bfd fast-detect command is not configured on the bundle.

Start timer:

Displays status of the BFD start timer that is configured using the bfd address-family ipv4 timers start command, with the following possible values:

  • x s—Number of seconds (from 60 to 3600) after startup of a BFD member link session to wait for the expected notification from the BFD peer to be received, so that the session can be declared up. If the SCN is not received after that period of time, the BFD session is declared down.

  • Off—The start timer is not configured, and a BFD session is only declared Down upon notification from the BFD server.

Neighbor-unconfigured timer:

Displays status of the BFD start timer that is configured using the bfd address-family ipv4 timers nbr-unconfig command, with the following possible values:

  • x s—Number of seconds (from 60 to 3600) to wait after receipt of notification that the BFD configuration has been removed by a BFD neighbor, so that any configuration inconsistency between the BFD peers can be fixed. If the BFD configuration issue is not resolved before the specified timer is reached, the BFD session is declared down.

  • Off—The neighbor-unconfigured timer is not configured, and a BFD session is only declared Down upon notification from the BFD server.

Preferred min interval:

Number of milliseconds (in the format x ms) as the minimum control packet interval for BFD sessions. The range is 15 to 30000.

Preferred multiple:

Value of the multiplier (from 2 to 50) that is used for echo failure detection, which specifies the maximum number of echo packets that can be missed before a BFD session is declared Down.

Destination address:

Destination IP address for BFD sessions on bundle member links that is configured using the bfd address-family ipv4 destination command. "Not configured" is displayed when no destination IP address is configured.

Port

Device

Label Distribution Protocol (LDP) address of the device where the interface port is located, with the following possible values:

  • address—IP address of the device.

  • Local—Interface port is on the local device.

State

Status of the port, with one of the following possible values

  • Active—Link can send and receive traffic.

  • BFD Running—Link is inactive because BFD is down or has not been fully negotiated.

  • Configured—Link is not operational or remains down due to a configuration mismatch. The link is not available for switchover from failure of an active link.

  • Hot Standby—Link is ready to take over if an active link fails and can immediately transition to Active state without further exchange of LACP protocol data units (PDUs).

  • Negotiating—Link is in the process of LACP negotiation and is being held in a lower LACP state by the peer (for example, because the link is Standby on the peer.)

  • Standby—Link is not sending or receiving traffic, but is available for swithchover from failure of an active link.

Port ID

ID of the interface port in the format x/y, with the following values:

  • x—Port priority as a 2-byte hexadecimal value.

  • y—Link ID as a 2-byte hexadecimal value.

B/W, kbps

Bandwidth of the interface port in kilobits per second.

State reason

Text string that is displayed beneath the bundle member listing explaining why a link has not reached Active state.

Table 3. State Reasons
Reason Description

BFD session is unconfigured on the remote end

The link is in BFD Running state because LACP is negotiated but the BFD session from the remote device has been unconfigured.

BFD state of this link is Down

The link is in BFD Running state because LACP is negotiated but the BFD session between the local system and the remote device is Down.

Bundle has been shut down

The link is in Configured state because the bundle it is configured as a member of is administratively down.

Bundle interface is not present in configuration

The link is in Configured state because the bundle it is configured as a member of has not itself been configured.

Bundle is in the process of being created

The link is in Configured state because the bundle it is configured as a member of is still being created.

Bundle is in the process of being deleted

The link is in Configured state because the bundle it is configured as a member of is being deleted.

Bundle is in the process of being replicated to this location

The link is in Configured state because the bundle it is configured as a member of is still being replicated to the linecard where the link is located.

Forced switchover to the mLACP peer

The link is in Configured state because it has been brought down as part of a forced switchover to the mLACP peer PoA. This happens only when brute force switchovers are configured.

ICCP group is isolated from the core network

The link is in Configured state because there is no connectivity through the network core for the ICCP group that the link and its bundle are part of. Therefore, the link has been brought down to prevent any traffic being sent by the LACP partner device.

Incompatible with other links in the bundle (bandwidth out of range)

The link is in Configured state because its bandwidth is incompatible with other links configured to be in the same bundle. The bandwidth may be too high or too low.

LACP shutdown is configured for the bundle

The link is in Standby state because the bundle is configured with LACP shutdown.

Incompatible with other links in the bundle (LACP vs non-LACP)

The link is in Configured state because its use of LACP is incompatible with other links configured in the same bundle. Some links might be running LACP while others are not.

Link is Attached and has not gone Collecting (reason unknown)

The link is in Negotiating state because the mLACP peer PoA has not indicated that the link has gone Collecting in the Mux machine. This could be because of an issue between the mLACP peer and its LACP partner or because this state has not been communicated to the local system.

Link is Collecting and has not gone Distributing (reason unknown)

The link is in Negotiating state because the mLACP peer PoA has not indicated that the link has gone Distributing in the Mux machine. This could be because of an issue between the mLACP peer and its LACP partner or because this state has not been communicated to the local system.

Link is being removed from the bundle

The link is being removed from the bundle and remains in Configured state while this happens.

Link is Defaulted; LACPDUs are not being received from the partner

The link is in Configured state because no LACPDUs are being received from the LACP partner device. Either the partner is not transmitting or the packets are getting lost.

Link is down

The link is in Configured state because it is operationally or administratively down.

Link is Expired; LACPDUs are not being received from the partner

The link is in Negotiating state because no LACPDUs have been received from the LACP Partner device in the Current-While period and the link is now marked as Expired in the Receive machine.

Link is in the process of being created

The link is in Configured state because the member configuration is still being processed.

Link is marked as Standby by mLACP peer

The link is in Standby state because this has been indicated by the mLACP peer PoA.

Link is Not Aggregatable (reason unknown)

The link is in Configured state because it is marked as an Individual link by the mLACP peer PoA.

Link is not forwarding viable and in standby state

The link is not available for data transmission and is configured forwarding-unviable.

Link is not operational as a result of mLACP negotiations

mLACP negotiations with the peer have led to this link being kept in Configured state. This is likely to indicate a misconfiguration between the two peer devices.

Link is Standby; bundle has more links than are supported

The link is in Standby state because the number of links in Selected state has already reached the hard platform limit on the number of active links.

Link is Standby due to maximum-active links configuration

The link is in Standby state because the number of links in Selected state has already reached the configured maximum active links threshold.

Link is waiting for BFD session to start

The link is in BFD Running state because LACP is negotiated but the BFD session has not started from the remote device.

Loopback: Actor and Partner have the same System ID and Key

The link is in Configured state because a loopback condition has been detected on the link—two links configured to be members of the bundle are actually connected to each other.

Not enough links available to meet minimum-active threshold

The link is in Standby state because there are not enough selectable links (i.e. links which meet the criteria to be marked Selected within the bundle) to meet the minimum active links/bandwidth threshold.

Partner has marked the link as Not Aggregatable

The link is in Configured state because it is marked as an Individual link by the LACP partner device.

Partner has not advertised that it is Collecting

The link is in Negotiating state because the LACP partner device has not advertised that the link is in Collecting state in its LACPDUs.

Partner has not echoed the correct parameters for this link

The link is in Negotiating state because the LACP partner device has not correctly echoed the local system's port information in the LACPDUs it is sending.

Partner is not Synchronized (Waiting, not Selected, or out-of-date)

The link is in Negotiating state because the mLACP peer PoA has not indicated that its LACP partner device is Synchronized. This could be because the devices are genuinely not Synchronized or because this state has not been communicated to the local system.

Partner is not Synchronized (Waiting, Standby, or LAG ID mismatch)

The link is in Negotiating state because the LACP partner device has not indicated that it is Synchronized in the LACPDUs it is sending. On the partner device the link could still be waiting for the Wait-While timer to expire, it could be held in Standby state, or there could be a misconfiguration leading to a LAG ID mismatch between links configured to be within the same bundle.

Partner System ID/Key do not match that of the Selected links

The link is in Configured state because the System ID or Operational Key specified by the LACP partner device does not match that seen on other Selected links within the same bundle. This probably indicates a misconfiguration.

Wait-while timer is running

The link is in Configured state because the Wait-While timer is still running and the new state has not yet been determined.

Table 5. show lacp bundle Field Descriptions

Field

Description

Flags

Describes the possible flags that may apply to a device or port, under the “Flags” field.

State

Describes the possible flags that may apply the port state, under the “State” field.

Port

Port identifier, in the rack/slot/module/port notation.

State

Provides information about the state of the specified port. Possible flags are:

  • 0—Port is not aggregatable.
  • 1—Port is out of sync with peer.
  • 2—Port is in sync with peer.
  • 3—Port is collecting.
  • 4—Port is collecting and distributing.

Flags

Provides information about the state of the specified device or port. Possible flags are:

  • A—Device is in Active mode.
  • P—Device is in Passive mode.
  • S—Device requests peer to send PDUs at a slow rate.
  • F—Device requests peer to send PDUs at a fast rate.
  • D—Port is using default values for partner information.
  • E—Information about partner has expired.

Port ID

Port identifier, expressed in the format Nxnnnn. N is the port priority, and nnnn is the port number assigned by the sending router.

Key

Two-byte number associated with the specified link and aggregator. Each port is assigned an operational key. The ability of one port to aggregate with another is summarized by this key. Ports which have the same key select the same bundled interface. The system ID, port ID and key combine to uniquely define a port within a LACP system.

System-ID

System identifier. The system ID is a LACP property of the system which is transmitted within each LACP packet together with the details of the link.

Field

Description

LACPDUs

Provides the following statistics for Link Aggregation Control Protocol data units (LACPDUs):

  • Port
  • Sent
  • Received
  • Last Cleared
  • Excess
  • Pkt Errors

Marker

Provides the following statistics for marker packets:

  • Received
  • Resp. Sent
  • Last Cleared
  • Excess
  • Pkt Errors

Note

 

The Marker Protocol is used by IEEE 802.3ad bundles to ensure that data no longer is transmitted on a link when a flow is redistributed away from that link.

Timeouts

Provides the following statistics for LACP timeouts:

  • Last LACP Timeout—The timestamp indicates the time of the last state change of a LACP timeout. The state change is both a timeout event and when the timeout event is no longer active.

  • LACP Timeout Transition—The number of times the LACP state has transitioned with a timeout since the time the device restarted or the interface was brought up, whichever is most recent. The state change is both a timeout event and when the timeout event is no longer active.

show lacp packet-capture

To display the contents of Link Aggregation Control Protocol (LACP) packets that are sent and received on an interface, use the show lacp packet-capture command in XR EXEC mode.

show lacp packet-capture [decoded] [in | out] {HundredGigabitEthernet | TenGigE} interface-path-id

Syntax Description

decoded

(Optional) Displays packet information in decoded form for the specified interface.

in

(Optional) Displays packet information for ingress packets only.

out

(Optional) Displays packet information for egress packets only.

HundredGigabitEthernet

Displays packet information for the Hundred Gigabit Ethernet interface specified by interface-path-id .

TenGigE

Displays packet information for the Ten Gigabit Ethernet interface specified by interface-path-id .

interface-path-id

Physical interface or virtual interface.

Note

 
Use the show interfaces command to see a list of all interfaces currently configured on the router.

For more information about the syntax for the router, use the question mark (? ) online help function.
