Enabling and Disabling Bridging
When you disable a bridge, you disconnect all its port networks from the bridge
entirely. Its bridge ports do not forward any packets, nor do they participate in
Spanning Tree operations. Nodes connected to the networks can still
communicate with each other, but they canÕt communicate with the bridge and
other networks connected to the bridge. When you enable bridge ports, they
move from the Disabled state through the Learning and Listening states to the
Forwarding or Blocking state (as determined by Spanning Tree).

When you disable bridging across the device, you simultaneously disable
bridging at all ports supported by the device.
