About fctimer Distribution
You can enable per-VSAN fctimer fabric distribution for all Cisco MDS 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 issue 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.
See
Enabling or Disabling fctimer Distribution
To enable or disable fctimer fabric distribution, follow these steps:
Command
Step 1
switch# config t
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.
