WEB OPERATION & CONFIGURATION
4.3.24 Ethernet Services
4.3.24.1 Ports
Port:
The port number. Port * rule applies to all ports.
DEI Mode:
The DEI mode for an NNI port determines whether frames transmitted on the port will have the DEI field in
the outer tag marked based on the color of the frame. The allowed values are:
Coloured:
The DEI is 1 for yellow frames and 0 for green frames.
Fixed:
The DEI value is determined by ECE rules.
4.3.24.2 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.
