L2CP
L2CP stands for Layer 2 Control Protocol and contains Ethernet control protocols such as Spanning Tree BPDUs,
LACP, Pause frames, etc. A L2CP frame has a specific destination address (DA) belonging to reserved multicast MAC
address ranges. MEF defines L2CP processing rules for Ethernet Frames carrying a MAC destination address (DA)
within the range of 01-80-C2-00-00-00 through 01-80-C2-00-00-0F and 01-80-C2-00-00-20 through 01-80-C2-00-00-2F.
Therefore, if a vendor defines L2CP frames outside the specified MAC DA ranges, the L2CP handling rules do not apply
to these frames.
