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 nonoverlapping domain IDs. This helps you in the
future if you need to implement IVR without the NAT feature.
If you configure an allowed list on one switch in the fabric, we recommend that you configure the same list
in all other switches in the fabric to ensure consistency or use CFS to distribute the configuration.

Configuring Allowed Domain ID Lists

You can configure the allowed domain ID list.
OL-27583-01

granted. The domain ID range is 1 to 239. The VSAN ID range
is 1 to 4093.
Resets the configured domain ID to factory defaults in the
specified VSAN. The configured domain ID becomes 0 preferred.
Configures the switch in the specified VSAN to request a
preferred domain ID 3 and accepts any value assigned by the
principal switch. The domain ID range is 1 to 239. The VSAN
ID range is 1 to 4093.
