Step 3 Click the Apply Changes icon to save these changes.
About Allowed Domain ID Lists
By default, the valid range for an assigned domain ID list is from 1 to 239. You can specify a list of
ranges to be in the allowed domain ID list and separate each range with a comma. The principal switch
assigns domain IDs that are available in the locally configured allowed domain list.
Use allowed domain ID lists to design your VSANs with non-overlapping domain IDs. This helps you
in the future if you need to implement IVR without the NAT feature.
Tip If you configure an allowed list on one switch in the fabric, we recommend you configure the same list
in all other switches in the fabric to ensure consistency or use CFS to distribute the configuration.
An allowed domain ID list must satisfy the following conditions:
• If this switch is a principal switch, all the currently assigned domain IDs must be in the allowed list.
• If this switch is a subordinate switch, the local runtime domain ID must be in the allowed list.
• The locally configured domain ID of the switch must be in the allowed list.
• The intersection of the assigned domain IDs with other already configured domain ID lists must not
be empty.
Configuring Allowed Domain ID Lists
To configure the allowed domain ID list using Fabric Manager, follow these steps:
Step 1 Expand Fabricxx > VSANxx > Domain Manager and then select Allowed in the Logical Domains pane
for the fabric and VSAN for which you want to set the allowed domain ID list.
You see the CFS configuration in the Information pane (see Figure 25-8).

Step 2
Set the Admin drop-down menu to enable and set the Global drop-down menu to enable.
