Enabling Bridging

3.3 ENABLING BRIDGING

Use the LCM bridge command to set bridging options for a single port or

a range of ports. The options include:

• off

• on (the default with BPDU enabled)

• noBPDU

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.

Use the

bridge <PORTS <{off|on|noBPDU}>> command to enable bridging

for a port or port range. For example, to turn on bridging for port 2:

FN100 > bridge 2 on

LCM responds:

Port 2 Sw1 bridging: Transparent Bridging

3.4 DISABLING BRIDGING

Use the bridge <PORTS> off command to turn off the bridging function

for a port or port range. For example, to turn off bridging for port 2:

FN100 > bridge 2 off

LCM responds:

Port 2 Sw1 bridging: Off

3.5 DISPLAYING BRIDGING FUNCTIONS

Use the bridge command to display the bridging functions that are

enabled for all ports.

NOTE

Selecting the noBPDU option could make your network

inoperable because the FN100 would be unable to detect

loops.
