Chapter 3: 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 is 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 on 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:
