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.
To discard the fctimer configuration changes, perform this task:
Command
Step 1
switch# configuration terminal
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
administrator performs this task, your changes to the pending database are discarded and the fabric lock
is released.
Tip 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

Database Merge Guidelines

When merging two fabrics, follow these guidelines:
•
•
The number of pending fctimer configuration operations cannot be more than 15. After 15 operations,
Note
you must commit or abort the pending configurations before performing any more operations.
See the
Cisco Nexus 5000 Series Switch CLI Software Configuration Guide
43-4
Be aware of the following merge conditions:
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.
The global fctimer values are not distributed.
–
Do not configure global timer values when distribution is enabled.
