Configuring Enhanced-Fabric-Inband Interface (eth2) Post DCNM Installation
During the DCNM installation, you can configure the In-Band Management interface. You must associate this network with the port group that corresponds to a fabric in-band connection. The In-Band Network provides reachability to the devices via the front-panel ports.
Note |
You cannot use Endpoint Locator and Telemetry features if the eth2 interface is not configured. |
To configure the eth2 interface for the in-band management network, use the appmgr setup inband command.
The following example shows a sample output for the appmgr setup inband command for a Cisco DCNM Standalone Appliance.
[root@dcnm]# appmgr setup inband
