Configuring Timer Per-VSAN

You can also issue the 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.

<strong>Caution	&nbsp;&nbsp;&nbsp;</strong>
</td>
<td>
<p>You cannot perform a nondisruptive downgrade to any earlier version that does not support per-VSAN 
FC timers.
</p>
</td>

</p>
<a name="wp1073232"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> This configuration must be propagated to all switches in the fabric&#8212;be sure to configure the same value 
in all switches in the fabric.

</p>
<a name="wp1073233"> </a><p class="pBody">
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. Refer to the <em class="cEmphasis">Cisco MDS 9000 
Family Troubleshooting Guide</em>.
