Timer Configuration Per-VSAN

You can also issue an fctimer for a specified VSAN to configure different TOV values for VSANs with
special links like FC or IP tunnels. 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.
Caution You cannot perform a nondisruptive downgrade to any earlier version that does not support per-VSAN
FC timers.
Note This configuration must be propagated to all switches in the fabric—be sure to configure the same value
in all switches in the fabric.
If a switch is downgraded to Cisco MDS SAN-OS Release 1.2 or 1.1 after the timer is configured for a
VSAN, an error message is issued to warn against strict incompatibilities.
To configure per-VSAN FC timers using Fabric Manager, follow these steps:
Step 1 Choose the VSAN for timer configuration from the Logical Domains pane. If a VSAN is not specified
when you change the policies, the changed value is applied to all VSANs in the switch.
Step 2 Expand Switches, expand FC Services and select Timers & Policies in the Physical Attributes tree.
You see timeouts for only switches in the selected VSAN shown in the Information pane.
Step 3 Click Change Timeouts to configure the time-out values.
