For example, the following illustration shows an IA with traffic being sent from port A to
port B, port B to port A, port B to port C, and port A to port C.
The corresponding bridge tables for address-based and flow-based bridging are shown in
the following table. The bridge table contains more information on the traffic patterns
when flow-based bridging is enabled compared to address-based bridging.
Address-Based Bridge Table
A (source)
B (source)
C (destination)
With the IA 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 based on Layer-2 traffic flows.
To enable flow-based bridging on a port, enter the following command in Configure
mode.
Configure a port for flow-based
bridging.
To change a port from flow-based bridging to address-based bridging, enter the following
command in Configure mode:
Change a port from flow-based
bridging to address-based bridging.
