The following example configures the timer value for VSAN 2:
switch(config#)# fctimer D_S_TOV 6000 vsan 2
Warning: The vsan will be temporarily suspended when updating the timer value This
configuration would impact whole fabric. Do you want to continue? (y/n) y
Since this configuration is not propagated to other switches, please configure the same value
in all the switches

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.

Enabling or Disabling fctimer Distribution

To enable or disable fctimer fabric distribution, perform this task:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# fctimer distribute
switch(config)# no fctimer distribute

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:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# fctimer commit

Purpose
Enters configuration mode.
Enables fctimer configuration distribution to all
switches in the fabric. Acquires a fabric lock and
stores all future configuration changes in the pending
database.
Disables (default) fctimer configuration distribution to
all switches in the fabric.
Purpose
Enters configuration mode.
Distributes the fctimer configuration changes to all
switches in the fabric and releases the lock. Overwrites
the effective database with the changes made to the
pending database.
