System Overview Tsunami MP.11 5012-SUR Installation and Management
Virtual Local Area Networks (VLANs)
For example, consider the above diagram which has a Radius Server at its back-end with two different BSU’s: BSU1 and
BSU2 and one SU in roaming. Let's assume that user has pre-configured SU VLAN configuration on Radius Server as:
SU in Access Mode & its Access VLAN ID as 100 and Access VLAN Priority as 5.
During the registration of SU with BSU1, BSU1 sends SU information in the form of Access-Request frame to the Radius
Server. The Radius Server validates SU’s MAC address and if the SU is authorised, it sends an Access-Accept frame
with Vendor Specific Attributes to BSU1 which has VLAN configuration on it. Thus, BSU1 receives VLAN configuration for
SU with the SU’s Access VLAN ID as 100 and access VLAN priority as 5.
When SU moves from the range of BSU1 to BSU2, a similar process takes place and the Radius Server provides the
same VLAN ID to the SU through BSU2. Thus the SU has same VLAN ID and Priority throughout its roaming. This
ensures a centralized management of SU’s VLAN configuration via the Radius Server.
When there is no VLAN configuration via Radius Server, BSU-SU follows the normal procedure of working.
NOTE: When SU VLAN Status is enabled, SU ignores the VLAN configuration from the Radius Server and BSU as SU
VLAN status has the highest priority.
