Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

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:

Procedure

PurposeCommand or Action

Enters configuration mode.switch# configuration terminal

Step 1

Discards the fctimer configuration changes in the

pending database and releases the fabric lock.

switch(config)# fctimer abort

Step 2

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.

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:

◦ 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.

The number of pending fctimer configuration operations cannot be more than 15. After 15 operations,

you must commit or abort the pending configurations before performing any more operations.
