About fctimer Distribution
You can enable per-VSAN fctimer fabric distribution for all Cisco SAN switches in the fabric. When you
perform fctimer configurations, and distribution is enabled, that configuration is distributed to all the switches
in the fabric.
You automatically acquire a fabric-wide lock when you enter the first configuration command after you
enabled distribution in a switch. The fctimer application uses the effective and pending database model to
store or commit the commands based on your configuration.

Step 3
Committing fctimer Changes
When you commit the fctimer configuration changes, the effective database is overwritten by the configuration
changes in the pending database and all the switches in the fabric receive the same configuration. When you
commit the fctimer configuration changes without implementing the session feature, the fctimer configurations
are distributed to all the switches in the physical fabric.
To commit the fctimer configuration changes, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Distributes the fctimer configuration changes to all
switches in the fabric and releases the lock. Overwrites
