Discarding fctimer Changes

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.
SUMMARY STEPS
1. configure terminal
2. fctimer abort
DETAILED STEPS
Command or Action
Step 1 configure terminal
Example:
switch# configure terminal
switch(config)#
Step 2
fctimer abort
Example:
switch(config)# fctimer abort

Overriding the Fabric Lock

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 administrator
performs this task, your changes to the pending database are discarded and the fabric lock is released.
The changes are only available in the volatile directory and are subject to being discarded if the switch is
restarted.
To use administrative privileges and release a locked fctimer session, use the clear fctimer session command.
switch# clear fctimer session

Fabric Database Merge Guidelines

When merging two fabrics, follow these guidelines:
• Be aware of the following merge conditions:
OL-27583-01
◦ The merge protocol is not implemented for distribution of the fctimer values. You must manually
merge the fctimer values when a fabric is merged.
◦ The per-VSAN fctimer configuration is distributed in the physical fabric.
◦ The fctimer configuration is only applied to those switches containing the VSAN with a modified
fctimer value.
