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

If a VSAN is not specified when you change the timer value, the changed value is applied to all VSANs
in the switch.
Note
To configure Fibre Channel timers across all VSANs, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Configures the R_A_TOV timeout value for all VSANs.
The units is milliseconds.
switch(config)# fctimer R_A_TOV
timeout
Step 2
This type of configuration is not permitted unless all
VSANs are suspended.
Timer Configuration Per-VSAN
You can also issue the fctimer for a specified VSAN to configure different TOV values for VSANs with
special links such as Fibre Channel. You can configure different E_D_TOV, R_A_TOV, and D_S_TOV
values for individual VSANs. Active VSANs are suspended and activated when their timer values are changed.
This configuration must be propagated to all switches in the fabric. Be sure to configure the same value
in all switches in the fabric.
Note
To configure per-VSAN Fibre Channel timers, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Configures the D_S_TOV timeout value (in
milliseconds) for the specified VSAN. Suspends the
switch(config#)# fctimer D_S_TOV
timeout vsan vsan-id
Step 2
VSAN temporarily. You have the option to end this
command, if required.
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
