Specifies the list of domain IDs that are allowed in the VSAN, and the configuration has different meanings in different scenarios:

1. Principal switch: Can only assign domains IDs within the allowed domain ID list. If the allowed domain ID list configured does not include any of the already assigned domain IDs or manually configured domain IDs, the configuration will fail.

2. Non-principal switch: The manually configured domain ID must be within the allowed domain ID list, or the configuration will fail. Besides, the domain ID assigned by principal switch must within the allowed domain ID list, or the switch will refuse the assigned domain ID and isolate the upstream interface. If the runtime domain ID for a switch is beyond the new configured ID list, the configuration will fail. The default value is a zero-length octet string. If This value is set with zero-length, the configuration will be cancelled in this VSAN.
