After making the configuration changes, you can choose to discard the changes by discarding the
changes instead of committing them. In either case, the lock is released.
To discard the fctimer configuration changes, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# fctimer abort

Fabric Lock Override

If you have performed a fctimer fabric task and have forgotten to release the lock by either committing
or discarding the changes, an administrator can release the lock from any switch in the fabric. If the

The changes are only available in the volatile directory and are subject to being discarded if the switch

To use administrative privileges and release a locked fctimer session, use the clear fctimer session
command.
switch# clear fctimer session

configuration is distributed in the physical fabric.
The fctimer configuration is only applied to those switches containing the VSAN with a
