A physical network can be partitioned into multiple, isolated distinct broadcast domains called virtual LANs or VLANs. The NAS server supports a maximum of 256 VLANs with a range of VLAN IDs from 1 to 4094 (0 and 4095 are invalid).

A server can provide access to a VLAN using a VLAN interface on an aggregate interface. Administrators can create a VLAN interface for each tagged VLAN for each aggregate interface over which the NAS server needs to communicate. For example, VLAN 1 on ag1 is different from VLAN 1 on ag2.

Note: If an address is assigned to a VLAN interface, the server discards untagged packets for that address. Therefore, do NOT create a VLAN interface for the native or otherwise untagged VLAN, as it can result in a loss of connectivity.
