Chapter 2: Bridging Configuration Guide
The corresponding bridge tables for address-based and flow-based bridging are shown
below. As shown, the bridge table contains more information on the traffic patterns when
flow-based bridging enabled compared to address-based bridging.
With the SSR configured in flow-based bridging mode, the network manager has “per
flow” control of layer-2 traffic. The network manager can then apply Quality of Service
(QoS) policies or security filters based layer-2 traffic flows.
To enable flow-based bridging on a port, enter the following command in Configure
Mode.
To change a port from flow-based bridging to address-based bridging, enter the following
command in Configure mode:
Configuring Spanning Tree
The SSR supports only one spanning tree process per SSR. By default, spanning tree is
disabled on the SSR. To enable spanning tree on the SSR, you perform the following task
on the ports where you want spanning tree enabled.
