Command History
Usage Guidelines You can enter a keyword to identify a Layer 2 control protocol. If you do not enter a protocol, all Layer 2

support these protocols.
peer Configures the EFP to allow Layer 2 protocols to peer with a neighboring switch on an
EFP-enabled interface. PDUs are processed locally.
tunnel Configures the EFP to tunnel Layer 2 control packets. Overwrites the PDU-destination
