Use this procedure to verify the operational status and configuration of the management interface using show commands.

Procedure

Enter the show interfaces mgmtEth instance command to display the management interface configuration.

The output shows that the management interface is administratively down.

You can also use the show interfaces summary or show interfaces brief commands in the Cisco IOS XR EXEC mode to verify the management interface status.

This example shows sample output from the show interfaces summary command.

This example shows sample output from the show interfaces brief command.

What to do next

Perform these steps if the management interface is administratively down.

Check the Ethernet cable connection.
Verify the IP address configuration of the management interface. For details on configuring the management interface, see Configure Management Interface.

Use the show running-config interface mgmtEth command to verify whether the management interface is in the no shut state.

This example shows sample output from the show running-config interface mgmtEth command.


RP/0/RP0/CPU0:ios# show running-config interface mgmtEth 0/RP0/CPU0/0                        
Wed Mar  4 06:17:33.833 UTC
interface MgmtEth0/RP0/CPU0/0
 ipv4 address dhcp
!


RP/0/RP0/CPU0:ios# show running-config interface mgmtEth 0/RP0/CPU0/0                       
Fri May  8 04:46:29.582 UTC
interface MgmtEth0/RP0/CPU0/0
 ipv4 address 10.105.57.103 255.255.255.128
!

The output shows that the management interface is in the no shut state.
