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.
If you configure an allowed list on one switch in the fabric, we recommend you configure the same list
Tip
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.

Purpose
Enters configuration mode.
Configures the switch in VSAN 8 to request a
preferred domain ID 3 and accepts any value
assigned by the principal switch. The domain is
range is 1 to 239.
Resets the configured domain ID to 0 (default) in
VSAN 8. The configured domain ID becomes 0
preferred.
Configures the switch in VSAN 237 to accept
only a specific value and moves the local
interfaces in VSAN 237 to an isolated state if the
requested domain ID is not granted.
Resets the configured domain ID to factory
defaults in VSAN 237. The configured domain ID
becomes 0 preferred.
