The commands in this section are only applicable to the dual switch with VLT topology.
The show vlt domain_id command validates the VLT configuration status. The Role for one switch in the VLT pair is primary, and its peer switch (not shown) is assigned the secondary role. Make sure that Peer-Routing is set to Enabled. The VLTi Link Status and VLT Peer Status must both be up.

The show vlt domain_id backup-link command is used to verify VLT peers are communicating on the backup link over the OOB management network. The Destination is the management IP address of the peer. The Peer Heartbeat status must be Up.
