Step 5
Set the Domain ID in the range of 97 (0x61) through 127 (0x7F).
a. Click the Configuration tab.
b. Click in the Config Domain ID column under the Configuration tab.
c. Click the Running tab and verify that the change has been made.
Note The domain ID range limit is to accommodate McData switches.
Note When changing the domain ID, the FC IDs assigned to N ports also change.
Step 6 Change the Fibre Channel timers (if they have been changed from the system defaults).
Note The Cisco, Brocade, and McData FC error detect (ED_TOV) and resource allocation (RA_TOV)
timers default to the same values. They can be changed if needed. The RA_TOV default is 10
seconds, and the ED_TOV default is 2 seconds. Per the FC-SW2 standard, these values must be
the same on each switch within the fabric.
a. Expand Switches > FC Services, and then choose Timers and Policies.
You see the timer settings in the Information pane.
b. Click Change Timeouts to modify the time-out values.
c. Click Apply to save the new time-out values.
Step 7 (Optional) Choose VSANxxx > Domain Manager, click the Configuration tab, and choose disruptive
or nonDisruptive in the Restart drop-down list to restart the domain.
