You can replace a member switch of a virtual chassis configuration without disrupting network service for the other members. You can retain the existing configuration of the member switch and apply it to a new member switch, or you can free up the member ID and make it available for assignment to a new member switch.
To replace a member switch, use the procedure that matches what you need to accomplish:
If you need to repair a member switch, you can remove it from the virtual chassis without disrupting network service for the other members. The master stores the configuration of the member ID so that it can be reapplied when the member switch (with the same base MAC address) is reconnected.
If you are unable to repair a member switch, you can replace it with a different member switch and retain the old configuration. The master stores the configuration of the member that was removed. When you connect a different member switch, the master assigns a new member ID. But the old configuration is still stored under the previous member ID of the previous member switch.
Note: If you have used a preprovisioned configuration, use the replace command to change the serial number in the virtual-chassis configuration file. Substitute the serial number of the replacement member switch (on the back of the switch) for the serial number of the member switch that was removed.
When you remove a member switch from the virtual chassis, the master keeps its member ID on reserve. To make that member switch’s member ID available for reassignment, use the request virtual-chassis recycle command.
