Verifying VCS Fabric configuration and RBridge ID
For the ISL to function correctly, the following criteria must be true:
• Both switches must have VCS Fabric mode enabled.
• Both switches must have the same VCS ID.
• Each switch must have a unique RBridge ID.
To check the criteria, complete the following steps.
1. Enter the show vcs command on each switch.
2. Depending on the output, proceed as follows:
• If the VCS Fabric mode is not enabled on either switch, enter the vcs enable command to enable
it.

vcsid command to correct the VCS ID on the switch that is in error.
