Virtual Local Area Networks (VLANs)

The management VLAN ID and management VLAN priority may be applied in any mode. The management stations tag
the management frames they send to the BSU or SU with the management VLAN ID configured in the device. The BSU
and SU tag all the management frames from the device with the configured management VLAN and priority.
BSU and SU in Transparent Mode
When the BSU is in Transparent mode, all associated SUs must be in Transparent mode.
How the BSU and SUs function in Transparent mode is described in the following table.
BSU in Trunk Mode and SU in Trunk/Access Mode
When the BSU is in Trunk mode, the associated SUs must be in either Trunk mode or Access mode. When an SU
associates to a BSU that is in Trunk mode, it gets the VLAN mode from the BSU.
How the BSU and SU function in Trunk mode, and the SU in Access mode, is described in the following table.
