Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration Guide, Releases 9.0, 9.1, 9.2, and 9.2.1

Configuring Interfaces

The "Configuring Interfaces" chapter applies to the ML-Series (ML100T-2, ML100X-8, ML1000-2 cards. This chapter describes basic interface configuration for the ML-Series card to help you get your ML-Series card up and running. Advanced packet-over-SONET/SDH (POS) interface configuration is covered in Chapter 8 "Configuring POS." For more information about the Cisco IOS commands used in this chapter, refer to the Cisco IOS Command Reference publication.

This chapter contains the following major sections:

•General Interface Guidelines

•Basic Interface Configuration

•Basic Fast Ethernet, Gigabit Ethernet, and POS Interface Configuration

•CRC Threshold Configuration

•Monitoring Operations on the Fast Ethernet and Gigabit Ethernet Interfaces

Note Complete the initial configuration of your ML-Series card before proceeding with configuring interfaces.

General Interface Guidelines

The main function of the ML-Series card is to relay packets from one data link to another. Consequently, you must configure the characteristics of the interfaces that receive and send packets. Interface characteristics include, but are not limited to, IP address, address of the port, data encapsulation method, and media type.

Many features are enabled on a per-interface basis. Interface configuration mode contains commands that modify the interface operation (for example, of an Ethernet port). When you enter the interface command, you must specify the interface type and number.

The following general guidelines apply to all physical and virtual interface configuration processes:

•All interfaces have a name that is composed of an interface type (word) and a Port ID (number). For example, FastEthernet 2.

•Configure each interface with a bridge-group or IP address and IP subnet mask.

•VLANs are supported through the use of subinterfaces. The subinterface is a logical interface configured separately from the associated physical interface.

•Each physical interface, including the internal POS interfaces, has an assigned MAC address.

MAC Addresses

Every port or device that connects to an Ethernet network needs a MAC address. Other devices in the network use MAC addresses to locate specific ports in the network and to create and update routing tables and data structures.

To find MAC addresses for a device, use the show interfaces command, as follows:

Router# sh interfaces fastEthernet 0

FastEthernet0 is up, line protocol is up

  Hardware is epif_port, address is 0005.9a39.6634 (bia 0005.9a39.6634)

     0 output buffer failures, 0 output buffers swapped out

Interface Port ID

The interface port ID designates the physical location of the interface within the ML-Series card. It is the name that you use to identify the interface that you are configuring. The system software uses interface port IDs to control activity within the ML-Series card and to display status information. Interface port IDs are not used by other devices in the network; they are specific to the individual ML-Series card and its internal components and software.

The ML100T-12 port IDs for the twelve Fast Ethernet interfaces are Fast Ethernet 0 through 11. The ML100X-8 port IDs for the eight Fast Ethernet interfaces are Fast Ethernet 0 through 7. The ML1000-2 port IDs for the two Gigabit Ethernet interfaces are Gigabit Ethernet 0 and 1. Both ML-Series cards feature two POS ports, and the ML-Series card port IDs for the two POS interfaces are POS 0 and POS 1. You can use user-defined abbreviations such as f0 to configure the Fast Ethernet interfaces, gi0 or gi1 to configure the two Gigabit Ethernet interfaces, and POS0 and POS1 to configure the two POS ports.

You can use Cisco IOS show commands to display information about any or all the interfaces of the ML-Series card.

Basic Interface Configuration

The following general configuration instructions apply to all interfaces. Before you configure interfaces, develop a plan for a bridge or routed network.

To configure an interface, do the following:

Step 1 Enter the configure EXEC command at the privileged EXEC prompt to enter global configuration mode.

Router> enable

Password:

Router# configure terminal

Router(config)#

Step 2 Enter the interface command, followed by the interface type (for example, fastethernet, gigabitethernet, or pos), and its interface port ID (see the "Interface Port ID" section).

For example, to configure a Gigabit Ethernet port, enter this command:

Router(config)# interface gigabitethernet number

Step 3 Follow each interface command with the interface configuration commands required for your particular interface.

The commands that you enter define the protocols and applications that will run on the interface. The ML-Series card collects and applies commands to the interface command until you enter another interface command or a command that is not an interface configuration command. You can also enter end to return to privileged EXEC mode.

Step 4 Check the status of the configured interface by entering the EXEC show interface command.

Router# sh interface fastEthernet 0

FastEthernet0 is up, line protocol is up

 Hardware is epif_port, address is 0005.9a39.6634 (bia 0005.9a39.6634)

Basic Fast Ethernet, Gigabit Ethernet, and POS Interface Configuration

ML-Series cards support Fast Ethernet, Gigabit Ethernet, and POS interfaces. This section provides some examples of configurations for all interface types.

To configure an IP address or bridge-group number on a Fast Ethernet, Gigabit Ethernet, or POS interface, perform the following procedure, beginning in global configuration mode:

Router(config)# interface type number

Router(config-if)# {ip address ip-address 
subnet-mask | bridge-group 
bridge-group-number}

Router(config-if)# no shutdown

Router(config)# end

Router# copy running-config startup-config

Configuring the Fast Ethernet Interfaces for the ML100T-12

To configure the IP address or bridge-group number, speed, duplex, and flow control on an ML100T-12 Fast Ethernet interface, perform the following procedure, beginning in global configuration mode:

Router(config)# interface fastethernet 
number

Router(config-if)# {ip address ip-address 
subnet-mask | bridge-group 
bridge-group-number}

Router(config-if)# [no] speed {10 | 100 | 
auto}

Router(config-if)# [no] duplex {full | half 
| auto}

Router(config-if)# flowcontrol send {on | 
off | desired}

Router(config-if)# no shutdown

Router(config)# end

Router# copy running-config startup-config

Example 6-1 shows how to do the initial configuration of an ML100T-12 Fast Ethernet interface with an IP address and autonegotiation.

Example 6-1 Initial Configuration of a ML100T-12 Fast Ethernet Interface

Router(config)# interface fastethernet 1

Router(config-if)# ip address 10.1.2.4 255.0.0.0

Router(config-if)# negotiation auto

Router(config-if)# no shutdown

Router(config-if)# end

Router# copy running-config startup-config

Configuring the Fast Ethernet Interfaces for the ML100X-8

The ML100X-8 supports 100BASE-FX full-duplex data transmission. You cannot configure autonegotiation or speed on its Fast Ethernet interfaces.

To configure the IP address or bridge-group number, or flow control on a Fast Ethernet interface, perform the following procedure, beginning in global configuration mode:

Router(config)# interface fastethernet 
number

Router(config-if)# {ip address ip-address 
subnet-mask | bridge-group 
bridge-group-number}

Router(config-if)# flowcontrol send {on | 
off | desired}

Router(config-if)# no shutdown

Router(config)# end

Router# copy running-config startup-config

Configuring the Gigabit Ethernet Interface for the ML1000-2

To configure IP address or bridge-group number, autonegotiation, and flow control on an ML1000-2 Gigabit Ethernet interface, perform the following procedure, beginning in global configuration mode:

Note The default setting for the negotiation mode is auto for the Gigabit Ethernet and Fast Ethernet interfaces. The Gigabit Ethernet port always operates at 1000 Mbps in full-duplex mode.

Router# interface gigabitethernet number

Router(config-if)# {ip address ip-address 
subnet-mask | bridge-group 
bridge-group-number}

Router(config-if)# [no] negotiation auto

Router(config-if)# flowcontrol {send | 
receive} {on | off | desired}

Router(config-if)# no shutdown

Router(config)# end

Router# copy running-config startup-config

Example 6-2 shows how to do an initial configuration of a Gigabit Ethernet interface with autonegotiation and an IP address.

Example 6-2 Initial Configuration of a Gigabit Ethernet Interface

Router(config)# interface gigabitethernet 0

Router(config-if)# ip address 10.1.2.3 255.0.0.0

Router(config-if)# negotiation auto

Router(config-if)# no shutdown

Router(config-if)# end

Router# copy running-config startup-config

Configuring the Gigabit Ethernet Interface for the ML-MR

Note Introducing a new section for configuring the Gigabit Ethernet Interface on the ML-MR card.

Configuring Gigabit Ethernet Remote Failure Indication (RFI)

Remote Failure Indication (RFI) is part of the IEEE 802.3z standard and is sent to exchange failure information as part of link negotiation. This feature improves communication between non-Cisco equipment and the ML1000-2. RFI is not on by default but can be turned on by the user. Disabling RFI is sometimes necessary when a non-Cisco piece of equipment does not support the IEEE 802.3z standard implementation of RFI.

RFI on the ML-Series card supports bidirectional RFI. When there is a a local fault on the ML-Series card, the ML-Series card will raise a local CARLOSS alarm and send its link partner an RFI. If an ML-Series card receives an RFI from its link partner, it raises the AUTONEG-RFI alarm and shuts down the Gigabit Ethernet port.

To enable RFI on a Gigabit Ethernet interface, perform the following procedure, beginning in global configuration mode:

Router (config)# interface gigabitethernet 
number

Router(config-if)# [no] rfi auto

Router(config)# end

Router# copy running-config startup-config

Example 6-3 shows how to do an initial configuration of RFI on a Gigabit Ethernet interface.

Example 6-3 RFI Configuration of a Gigabit Ethernet Interface

Router(config)# interface gigabitethernet 0

Router(config-if)# rfi auto

Router(config-if)# end

Router# copy running-config startup-config

Monitoring and Verifying Gigabit Ethernet Remote Failure Indication (RFI)

After RFI is configured, you can verify that RFI is enabled by using the global command show running configuration. Example 6-4 shows the output from this command, and the "rfi auto" line under each of the Gigabit Ethernet port's output signifies RFI is enabled on these ports.

More specific RFI information is revealed with the global show controller gigabit ethernet [ 0 | 1] command:

•Example 6-5 shows the full output from this command on a near-end ML-Series card when no faults are detected at the near-end or far-end. The Remote Fault Indication is 00 or no error, and the Local Fault Indication is 00 or no error.

•Example 6-6 shows the partial output from this command on a near-end ML-Series card when a fault is detected at the near-end. The Remote Fault Indication is 00 or no error, but the Local Fault Indication is 01 or link error.

•Example 6-7 shows the partial output from this command on a far-end ML-Series card when a fault is detected at the near-end. The Remote Fault Indication is 01 or link error, and the Local Fault Indication is 00 or no error.

Note If the far-end link partner resets within approximately two minutes of the near-end ML-Series card sending an RFI signalling link error, the link partner will not display the RFI link error indication when back up.

Example 6-4 show run Command Output for RFI

Configuring the POS Interfaces (ML100T-12, ML100X-8, ML1000-2, and ML-MR-10)

Encapsulation changes on POS ports are allowed only when the interface is in a manual shutdown (ADMIN_DOWN). For advanced POS interface configuration, see Chapter 8 "Configuring POS."

To configure the IP address, bridge group, or encapsulation for the POS interface, perform the following procedure, beginning in global configuration mode:

Router(config)# interface pos number

Router(config-if)# {ip address ip-address 
subnet-mask | bridge-group 
bridge-group-number}

Router(config-if)# shutdown

Router(config-if)# encapsulation type

Router(config-if)# no shutdown

Router(config)# end

Router# copy running-config startup-config

CRC Threshold Configuration

You can configure a span shutdown when the ML-Series card receives CRC errors at a rate that exceeds the configured threshold and configured soak time. ML-Series cards support CRC threshold configuration functionality on FE/GE/POS and RPR-IEEE interfaces. For configuration sample for RPR-IEEE interfaces, see Chapter 30 "Configuring IEEE 802.17b Resilient Packet Ring on the ML-MR-10 Card."

To enable and configure the triggers for CRC errors on POS, perform the following procedure, beginning in global configuration mode:

Router(config)# int pos0

Router(config-if)# trigger crc-error

threshold threshold_value

Router(config-if)# no trigger crc-error 
threshold threshold_value

Router(config)# int pos0

Router(config-if)# trigger crc-error delay 
soak_time_in_minutes

Router(config-if)# no trigger crc-error 
delay soak_time_in_minutes

Router(config)# int pos0

Router(config-if)# trigger crc-error action

Router(config-if)# no trigger crc-error 
action

Monitoring Operations on the Fast Ethernet and Gigabit Ethernet Interfaces
