L2 protocol packet handling

The following content has been modified in the Multi-Chassis Trunking (MCT) chapter in the “L2

protocol packet handling” section.

If the no cluster-l2protocol-forward command is configured on global basis or

cluster-l2protocol-forward disable is configured on a port, the STP protocol packets coming on the

ICL ports of MCT VLANs are dropped.

All other L2 protocol packets will be flooded on the MCT VLANs or dropped. The

cluster-l2protocol-forward command is not applicable to these protocol packets. It only applies to

STP or RSTP BPDU packets on the ICL ports only.

OpenFlow configuration considerations

After you enable OpenFlow on a device, you can configure, generate, and monitor flows on the

ports configured on the device from a controller on OpenFlow-enabled ports. The Brocade device

flow table is entirely under the control of the OpenFlow Controller. Keep in mind the following when

you configure and monitor OpenFlow features on the devices:

• OpenFlow action can duplicate traffic to 16 ports.

• It supports Administratively down (OFPPC_PORT_DOWN) through Port Modification Message.
