3. From the Spanning Tree pull-down menu, select to Enable or
Disable spanning tree protocol on this port.
4. From the Fast Start pull-down menu, select to Enable or
Disable. When enabled, Fast Start mode ports begin forwarding
traffic without waiting for the spanning tree negotiation to
complete. Fast start eliminates the waiting time of listen and
learn states. Ports immediately enter the forward state.
5. From the Known Mode pull-down menu, select to Enable or
Disable. Selecting Enable limits the packets with unknown
unicast destination addresses flooded to this port. For example, if
a known end-station or file server is connected to the port,
there’s no need to flood unknown unicasts to that port. You
must manually enter a static MAC address for the station
actually attached to the port.
6. From the 3Com Mapping Table pull-down menu, select an
assignment to specify how incoming tagged frames from 3Com
equipment are mapped to Lucent VLANs. Refer to “Creating
3Com Mapping Tables”, in
the Cajun P550/P220 Switch Operation
Guide , for more information on 3Com Mapping Tables.
7. Click APPLY to save your changes, or CANCEL to restore
