Cisco IOS XR Commands by Software Package, Release 3.8.0

Management Ethernet Interface Commands on Cisco IOS XR Software

This module describes the Cisco IOS XR commands used to configure the Management Ethernet interfaces.

duplex (Management Ethernet)

To configure duplex mode operation on a Management Ethernet interface, use the duplex command in interface configuration mode. To return the interface to autonegotiated duplex mode, use the no form of the duplex command.

duplex {full | half}

no duplex

Syntax Description

Defaults

Autonegotiates duplex operation

Command Modes

Interface configuration

Command History

Usage Guidelines

To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.

Examples

The following example shows how to configure the Management Ethernet interface to operate in full duplex mode:

RP/0/RP0/CPU0:router(config)# interface MgmtEth 0/RP0/CPU0/0

RP/0/RP0/CPU0:router(config-if)# duplex full

The following example shows how to configure the Management Ethernet interface to operate in half duplex mode:

RP/0/RP0/CPU0:router(config)# interface MgmtEth 0/RP0/CPU0/0

RP/0/RP0/CPU0:router(config-if)# duplex half

The following example shows how to return a Management Ethernet interface to autonegotiated duplex mode:

RP/0/RP0/CPU0:router(config)# interface MgmtEth 0/RP0/CPU0/0

RP/0/RP0/CPU0:router(config-if)# no duplex

Related Commands

interface MgmtEth

To enter interface configuration mode for the Management Ethernet interface, use the interface MgmtEth command in global configuration mode. To delete a Management Ethernet interface configuration, use the no form of this command.

interface MgmtEth interface-path-id

no interface MgmtEth interface-path-id

Syntax Description

Defaults

No default behavior or values

Command Modes

Global configuration

Command History

Usage Guidelines

To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.

For the interface-path-id argument, use the following guidelines:

•If specifying a physical interface, the naming notation is rack/slot/module/port. The slash between values is required as part of the notation. An explanation of each component of the naming notation is as follows:

–rack: Chassis number of the rack.

–slot: Physical slot number of the line card.

–module: Module number. A physical layer interface module (PLIM) is always 0.

–port: Physical port number of the interface.

•If specifying a virtual interface, the number range varies, depending on interface type.

Examples

The following example shows how to enter interface configuration mode for a Management Ethernet interface:

RP/0/RP0/CPU0:router(config)# interface MgmtEth 0/RP0/CPU0/0

RP/0/RP0/CPU0:router(config-if)#

Related Commands

mac-address (Management Ethernet)

To set the MAC layer address of a Management Ethernet interface, use the mac-address command in interface configuration mode. To return the interface to its default MAC address, use the no form of the mac-address command.

mac-address value1.value2.value3

no mac-address

Syntax Description

Defaults

The default MAC address is read from the hardware burned-in address (BIA).

Command Modes

Interface configuration

Command History

Usage Guidelines

To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.

The MAC address must be in the form of three 4-digit values (12 digits in dotted decimal notation).

Examples

The following example shows how to set the MAC address of the Management Ethernet interface located at 0/RP0/CPU0/0:

RP/0/RP0/CPU0:router(config)# interface MgmtEth 0/RP0/CPU0/0 

RP/0/RP0/CPU0:router(config-if)# mac-address 0001.2468.ABCD

Related Commands

speed (Management Ethernet)

To configure the speed for a Management Ethernet interface, enter the speed command in interface configuration mode. To return the system to autonegotiate speed, use the no form of the speed command.

speed {10 | 100 | 1000}

no speed

Syntax Description

Defaults

Interface speed is autonegotiated.

Command Modes

Interface configuration

Command History

Usage Guidelines

To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.

Note Keep in mind that both ends of a link must have the same interface speed. A manually configured interface speed overrides any autonegotiated speed, which can prevent a link from coming up if the configured interface speed at one end of a link is different from the interface speed on the other end.

Table 76 describes the performance of the system for different combinations of the duplex and speed modes. The specified duplex command configured with the specified speed command produces the resulting system action.

Examples

The following example shows how to configure the Management Ethernet interface to transmit at one gigabit:

RP/0/RP0/CPU0:router(config)# interface MgmtEth 0/RP0/CPU0/0

RP/0/RP0/CPU0:router(config-if)# speed 1000
