dmAllowedDomainIDListTable
This table contains list of allowed domain IDs in the local VSANs. So in a VSAN, domain IDs can be assigned only from the allowed list. All the domain IDs which are not allowed are reserved. Note that this is possible in a VSAN only if the local device is the principal switch in that VSAN.
This OID is also declared by other modules:
CISCO-DM-MIB
