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
Note
in all switches in the fabric.
You can configure per-VSAN Fibre Channel timers.
