Intra-Cell Blocking Group Rules
The following rules apply to Intra-Cell Blocking Groups:
• One SU can be assigned to more than one group.
• An SU that has not been assigned to any group cannot communicate to any other SU connected to the same
or different Base Station Unit.
Example of Intra-Cell Blocking Groups
Four Intra-Cell Blocking Groups have been configured on one Base Station Unit. SUs 1 through 6 are registered
to Base Station Unit 1. SUs 7 through 9 are registered to Base Station Unit 2.
Intra-Cell Blocking Group Example
Group 1 Group 2 Group 3 Group 4
SU 1 SU 2 SU 6 SU 8
SU 4 SU 3 SU 1 SU 9
SU 5 SU 8 SU 3 SU 2
In this example, SU 1 belongs to two groups, Group 1 and Group 3. Therefore, packets from SU 1 destined to SU
4, SU 5, SU 6, and SU 3 are not blocked. However, SU 9 belongs to group 4 only and packets from SU 9 are
blocked unless sent to SU 8 or SU 2.
Achieving Communication Between Two SUs
In a multipoint configuration, an SU can communicate with another SU through the BSU when in Bridge mode by
default. Use the intra-cell blocking feature if this is not desired. In a routing configuration, each of the SUs must
have a different subnet on their Ethernet port to distinguish traffic for each SU, and each subnet must be entered
into a routing rule in the BSU as well as into an upstream router. The wireless side of all SUs must share the
same subnet with the BSU wireless interface. These IP addresses must be used as next hop when creating the
routes for the SU subnets.
10) Configure VLAN Parameters
Virtual LAN (VLAN) implementation in the Tsunami MP.11 products:
• Lets the BSU and SU be used in a VLAN-aware network.
• Processes IEEE 802.1Q VLAN-tagged packets.
Network resources behind the BSU and SU can be assigned to logical groups.
VLAN Modes
Transparent Mode
Transparent mode applies to both the SU and the BSU. This mode is equivalent to NO VLAN support and is the
default mode. It is used when the devices behind the SU and BSU are both VLAN aware or unaware. The
SU/BSU transfers both tagged and untagged frames received on Ethernet or WORP interface. Both tagged and
untagged management frames can access the device.
Trunk Mode
Trunk mode VLAN applies to both the SU and the BSU. It is used when all devices behind the SU and BSU are
VLAN aware. The SU and BSU transfer only tagged frames received on Ethernet or WORP interface.
