Gigabit Ethernet Line Card

The Gigabit Ethernet line card provides Cisco 12000 series routers with an optical Ethernet interface on a single card that operates faster than 1-Gbps. The card interfaces with the switch fabric in the Cisco 12000 series router and provides one Gigabit Ethernet SC single-mode or multimode connection. This connection is concatenated, which provides for increased efficiency by eliminating the need to partition the bandwidth.

For more information on the Gigabit Ethernet line card, refer to the Gigabit Ethernet Line Card Installation and Configuration note. For more information on the Cisco 12000 series, refer to the Cisco 12012 Gigabit Switch Router Installation and Configuration Guide and the Cisco 12008 Gigabit Switch Router Installation and Configuration Guide.

Document Conventions

Command descriptions use these conventions:

Boldface indicates commands and keywords that are entered literally as shown.
Italics indicate arguments for which you supply values; in contexts that do not allow italics, arguments are enclosed in angle brackets ( >).
Square brackets ([ ]) indicate optional elements.
Braces ({ }) group required choices, and vertical bars ( | ) separate alternative elements.
Braces and vertical bars within square brackets ([{ | }]) indicate a required choice within an optional element.

Gigabit Ethernet Command Reference

This section documents new or modified commands that support the Gigabit Ethernet line card. All other commands used with this feature are documented in the Cisco IOS Release 11.2 command references.

ip accounting mac-address
loopback
mac-address
negotiation auto
show controller (Gigabit Ethernet)
show controller gigabitethernet
show controller gigabitethernet cam
show controller gigabitethernet gbic
show controller gigabitethernet mac
show controller gigabitethernet rewrite
show controller gigabitethernet rx_trans
show controller gigabitethernet sop

To use the show commands on a line card, you can use the execute-on privileged EXEC command or you can connect to the Cisco IOS image running on the line card by using the attach privileged EXEC command.

ip accounting mac-address

To enable IP accounting on a LAN interface based on the source and destination MAC address, use the ip accounting mac-address interface configuration command. To disable IP accounting based on the source and destination MAC address, use the no form of this command.

ip accounting mac-address {input | output}
no ip accounting mac-address {input | output}

Syntax Description


input	Perform accounting based on the source MAC address on received packets.
output	Perform accounting based on the destination MAC address on transmitted packets.

Default

Disabled

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.1 CC. It was modified for Cisco IOS Release 11.2GS.

This feature is supported on Gigabit Ethernet, FastEthernet, and FDDI interfaces and subinterfaces.

To display the MAC accounting information, use the show interface mac EXEC command.

When MAC address accounting is enabled, header compression is turned off. This is done so the MAC information can be extracted from the header. When MAC address accounting is turned off, header compression is enabled.

Note Performance on the Gigabit Ethernet line card is degraded when MAC address accounting is turned on.

The MAC address accounting feature provides accounting information for IP traffic based on the source and destination MAC address on LAN interfaces. This feature calculates the total packet and byte counts for a LAN interface that receives or sends IP packets to or from a unique MAC address. It also records a timestamp for the last packet received or sent. With this feature you can determine how much traffic is being sent to and/or received from various peers at NAPS/peering points.

Examples

The following example enables IP accounting based on the source and destination MAC address for received and transmitted packets:

router# configure terminal

router(config)# interface gigabitethernet 4/0

router(config-if)# ip accounting mac-address input

router(config-if)# ip accounting mac-address output

router(config-if)# end

router#

loopback

To set a loopback mode for the Gigabit Ethernet line card, use the loopback interface configuration command. To remove loopback mode, use the no form of the command.

loopback [ internal | external ]
no loopback

Syntax Description


internal	(Optional) Perform the loopback at the internal MAC controller.
external	(Optional) Perform the loopback using an external loopback connector.

Default

This command has no default.

Command Mode

Interface configuration

Usage Guidelines

This command was modified in Cisco IOS Release 11.2 GS to support the Gigabit Ethernet line card on the Cisco 12000 series Gigabit Switch Routers.

Examples

The following example defines an external loopback mode for the Gigabit Ethernet line card:

router# configure terminal

router(config)# interface gigabitethernet 4/0

router(config-if)# loopback external

router(config-if)# end

router#

Related Commands

mac-address

To assign a MAC address to the Gigabit Ethernet line card, use the mac-address interface configuration command. To remove the MAC address, use the no form of the command.

mac-address xx.xx.xx
no mac-address xx.xx.xx

Syntax Description


xx	A two-byte hexadecimal value.

Default

This command has no default.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 10.0.

Examples

The following example defines a MAC hardware address for the Gigabit Ethernet line card:

router# configure terminal

router(config)# interface gigabitethernet 4/0

router(config-if)# mac-address 6000.0001.0003

router(config-if)# end

router#

Related Commands

negotiation auto

To configure auto negotiation on a Gigabit Ethernet line card, use the negotiation auto interface configuration command. To remove the auto negotiation, use the no form of the command.

negotiation auto
no negotiation auto

Syntax Description

This command has no keywords or arguments.

Default

This command has no default.

Command Mode

Interface configuration

Usage Guidelines

This command was added in Cisco IOS Release 11.2 GS to support the Cisco 12000 series Gigabit Switch Routers.

Note This command is not implemented in the initial versions of Cisco IOS Release 11.2 GS.

Examples

The following example defines a MAC hardware address for the Gigabit Ethernet line card:

router# configure terminal

router(config)# interface gigabitethernet 4/0

router(config-if)# negotiation auto

router(config-if)# end

router#

Related Commands

show controller (Gigabit Ethernet)

To display all available information about the Gigabit Ethernet line card, use the show controller privileged EXEC command.

show controller

Syntax Description

This command has no keywords or arguments.

Command Mode

Privileged EXEC

Usage Guidelines

This command was added in Cisco IOS Release 11.2 GS to support the Cisco 12000 series Gigabit Switch Routers.

You must first use the attach privileged EXEC command to access the Cisco IOS software image on a line card before using line card-specific show commands. Alternatively, you can use the execute-on privileged EXEC command to execute a show command on a specific line card.

show controller gigabitethernet

To display information for the Gigabit Ethernet line card, use the show controller gigabitethernet privileged EXEC command.

Syntax Description


cam	Display CAM information.
gbic	Display Gigabit Ethernet interface information.
mac	Display MAC information.
rewrite	Display the local MAC rewrite table.
rx_trans	Display the receiver GigaTranslator information.
sop	Display certain POS-specific information.

Command Mode

Privileged EXEC

Usage Guidelines

This command was added in Cisco IOS Release 11.2 GS to support the Cisco 12000 series Gigabit Switch Routers.

To display all information about the Gigabit Ethernet line card, use the show controller privileged EXEC command.

Sample Display

Refer to the individual command reference pages for each form of the show controller gigabitethernet output.

Syntax Description

This command has no keywords or arguments.

Command Mode

Privileged EXEC

Usage Guidelines

This command was added in Cisco IOS Release 11.2 GS to support the Cisco 12000 series Gigabit Switch Routers.

The CAM hardware acts as a destination address filter. In some instances, such as when enabling IP multicast, the CAM is put in multicast promiscuous mode. A non-zero CAM mask indicates a series of contiguous entries, starting from the indicated MAC address. For example, the following shadow CAM entry indicates a range of MAC addresses from 0100.5e00.0000 to 0100.5e00.00FF inclusive:

MAC addr: 0100.5e00.0000, mask: 0000.0000.00ff
