3.2 ENABLING BRIDGING
The LCM bridge command allows you to set bridging options for a single
port or a range of ports. The options include:
• off
• on (the default with BPDU enabled)
• no BPDU
BPDU (Bridge Protocol Data Unit) is a data unit transmitted as part of the
IEEE 802.1d Spanning Tree protocol. The exchange of BPDUs allows
bridges within a network to logically configure the network as a single
spanning tree.
Using LCM to enable bridging for a port or port range, at the LCM
prompt:
1. Type bridge [PORT-RANGE [{off|on|noBPDU}]]
For example, bridge 2 on would enable bridging on port 2.
LCM responds:
NOTE
When you change the subnet mask for a port, you must also
enter the IP address for that port. Make sure you enter the IP
address for the port correctly; whatever you enter becomes the
IP address.
NOTE
Selecting the noBPDU option could make your network
inoperable because the FN10 would be unable to detect loops.
