Management Ethernet Interface Commands on the Cisco ASR 9000 Series Router

Management Ethernet Interface Commands on the Cisco ASR 9000 Series Router

This module provides command line interface (CLI) commands for configuring Management Ethernet interfaces on the Cisco ASR 9000 Series Router.

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

full

Configures the Management Ethernet interface to operate in full duplex mode.

half

Configures the Management Ethernet interface to operate in half duplex mode.

Command Default

Autonegotiates duplex operation

Examples

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

RP/0/RSP0/CPU0:router(config)# interface MgmtEth 0/RSP0/CPU0/0
RP/0/RSP0/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/RSP0/CPU0:router(config)# interface MgmtEth 0/RSP0/CPU0/0
RP/0/RSP0/CPU0:router(config-if)# duplex half
   

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

RP/0/RSP0/CPU0:router(config)# interface MgmtEth 0/RSP0/CPU0/0
RP/0/RSP0/CPU0:router(config-if)# no duplex

Command

Description

interface MgmtEth

Enters interface configuration mode for the Management Ethernet interface.  

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.

Command

Description

duplex (Management Ethernet)

Configures duplex mode operation on a Management Ethernet interface.  

mac-address (Management Ethernet)

Sets the MAC layer address of a Management Ethernet interface.  

speed (Management Ethernet)

Configures the speed for a Management Ethernet interface.  

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.

Command Default

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

Command Modes

Interface configuration

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

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

Examples

This example shows how to set the MAC address of the Management Ethernet interface located at 0/RSP0 /CPU0/0:

RP/0/RSP0/CPU0:router(config)# interface MgmtEth 0/RSP0/CPU0/0
RP/0/RSP0/CPU0:router(config-if)# mac-address 0001.2468.ABCD

Command

Description

interface MgmtEth

Enters interface configuration mode for the Management Ethernet interface.  

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

10

Configures the interface to transmit at 10 Mbps.

100

Configures the interface to transmit at 100 Mbps.

1000

Configures the interface to transmit at 1000 Mbps (1 Gbps).

Command Default

Interface speed is autonegotiated.

Command Modes

Interface configuration

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines


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 1 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.
