The following example shows the show spanning-tree rstp command.
The bold section displays the RSTP state of port channels in the VLT domain. Port channel 100 is used in the VLT interconnect
trunk (VLTi) to connect to VLT peer2. Port channels 110, 111, and 120 are used to connect to access switches or servers (vlt).

Additional VLT Sample Configurations

To configure VLT, configure a backup link and interconnect trunk, create a VLT domain, configure a backup link and
interconnect trunk, and connect the peer switches in a VLT domain to an attached access device (switch or server).
Review the following examples of VLT configurations.
Configuring Virtual Link Trunking (VLT Peer 1)
Enable VLT and create a VLT domain with a backup-link and interconnect trunk (VLTi).
