Changing an RBridge ID on a switch within a fabric
It may become necessary to change the RBridge ID number on a switch that rebooted and has become orphaned from the cluster.
- Backup the global configuration before changing the RBridge ID, because the local configuration will be reset to default values. Refer to Backing up configurations.
On the rebooted switch, execute the
chassis disable command.
switch# chassis disable
From the fabric principal switch, execute the
no vcs enable rbridge-id
rbridge-id command, where
rbridge-id is the switch that was orphaned.
switch# no vcs enable rbridge-id 3
- On the rebooted switch, execute the vcs rbridge-id rbridge-id command, where rbridge-id is the RBridge you want to use.
- The VCSID should already be set, if it's not set it with the vcs rbridge-id rbridge-id.
Reboot the orphaned switch.
The following behavior will take effect after the switch reboots:
- All interfaces will be in shutdown state. You must perform a no shutdown command on ISL interfaces before the switch will rejoin the cluster.
- The original configuration will be lost and the switch will have a default configuration when it rejoins the cluster with the new RBridge ID.
show vcs detail command to verify that the switch is in the fabric.
