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 |
Enters interface configuration mode for the Management Ethernet interface. |
show interfaces |
Displays statistics for all interfaces configured on the router. |
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
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. |
Defaults
No default behavior or values

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
value1. |
High 2 bytes of the MAC address in hexadecimal. Range is from 0 to ffff. |
value2. |
Middle 2 bytes of the MAC address in hexadecimal. Range is from 0 to ffff. |
value3 |
Low 2 bytes of the MAC address in hexadecimal. Range is from 0 to ffff. |
Defaults
The default MAC address is read from the hardware burned-in address (BIA).

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

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.

no speed
Syntax Description

If you need assistance with your task group assignment, contact your system administrator.

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.
