Description
Use the bridge mac-address command to manually configure a static address table
entry of bridge.
Use the undo bridge mac-address command to delete the static address entry.
Normally, a bridge can automatically create dynamic address map entry after obtaining
associations between MAC addresses and interfaces. You can however
administratively create static address map entries, which will never age out.
