Verify management interface status

Updated: September 10, 2026

Want to summarize with AI?

Verify the configuration and operational status of the management Ethernet interface on Cisco NCS 1014 using the appropriate show commands.

Use this task to confirm that the management Ethernet interface of Cisco NCS 1014 is up and to view its configuration and traffic counters.

Checking the management Ethernet interface status helps ensure the device is reachable for management and operating as expected. You can also view detailed configuration and traffic counters during troubleshooting.

Procedure

Run the show interfaces mgmtEth instance command to display the configuration of the management Ethernet interface, including the IP address, the MTU, the bandwidth, the duplex mode, and the traffic counters.

In the previous output, the management interface is administratively up.

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

Optionally, run the show interfaces summary and show interfaces brief commands in Cisco IOS XR EXEC mode to verify the management interface status.

The following example shows sample output from the show interfaces summary command:

RP/0/RP0/CPU0:ios#show interfaces summary

You can confirm whether the management Ethernet interface is administratively and operationally up and review its configuration and traffic counters.

What to do next

If the management interface is administratively down, perform the following actions:

Check the Ethernet cable connection.
Verify the IP configuration of the management interface. For details about configuring the management interface, see Configure a management interface.
Verify that the management interface is in the no shut state by running the show running-config interface mgmtEth command.

The following 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
interface MgmtEth0/RP0/CPU0/0
 ipv4 address 10.105.57.37 255.255.255.128
