System Configuration
Mode – The wireless bridge is set to operate as a Slave or Master
unit:
•
Master Mode: In a point-to-multipoint network configuration,
only one wireless bridge unit must be a Master unit (all others
must be Slave units). A Master wireless bridge provides
support for up to 16 MAC addresses in the WDS forwarding
table. The MAC addresses of all other Slave bridge units in the
network must be configured in the forwarding table.
•
Slave Mode: A Slave wireless bridge provides support for only
one MAC address in the WDS forwarding table. A Slave bridge
communicates with only one other wireless bridge, either
another Slave bridge in a point-to-point configuration, or to the
Master bridge in a point-to-multipoint configuration.
Port Number (Master bridge only) – The wireless port identifier.
