Description
The
port
flow-bridging
command changes the specified ports from using address-
based bridging to using flow-based bridging. A port can use only one type of bridging
at a time.
Each port has an L2 lookup table where MAC address or flows are stored.
If the port is configured for address-based bridging (default), each L2 table entry
consists of a MAC address and a VLAN ID.
If the port is configured for flow-based bridging, each L2 table entry consists of a
source MAC address, a destination MAC address, and a VLAN ID.
Suppose that a port on the SSR is connected to a hub that is connected to three
workstations, A, B, and C. If each workstation is talking to one another and sending
broadcast traffic, the L2 table on the SSR’s port would contain the following entries
for the workstations. Assume that the VLAN ID is “1” for all entries.
If the ports are configured for address-based bridging:
MAC address A
MAC address B
MAC address C
MAC broadcast address
