Configuration Guide Configuring Transparent Transmission of Protocol Frames
Configuring Transparent
Transmission of Protocol Frames
Overview
The protocol frame transparent transmission function enables protocol frames to be forwarded to other
network devices when a specific protocol is enabled.
The protocols that support transparent transmission include BPDU, GVRP, 802.1X, reserved multicast
protocol, and Cisco private STP (PVST) protocol. The protocol frames are described as follows:
BPDU frames: Frames used in spanning tree protocols, including frames stipulated by the IEEE
standards and Ruijie private protocol frames. This document configures transparent transmission for
Ruijie's BPDU frames, which are identified by the Layer 2 destination MAC address 01D0:F800:0000.
GVRP frames: Frames used for VLAN registration, including frames stipulated by the IEEE standards
and Ruijie private protocol frames. This document configures transparent transmission for Ruijie private
GVRP frames, which are identified by the Layer 2 destination MAC address 01D0:F800:0021.
802.1X frames: Standard frames developed by the IEEE for authentication of users accessing the
network, including frames stipulated by the IEEE standards and private protocol frames of Ruijie. The
frames are identified by the Layer 2 destination MAC address, which is 0180:C200:0003 for standard
protocol frames and 01D0:F800:0003 for Ruijie 802.1X frames.
Reserved multicast protocol frames: Reserved multicast addresses stipulated by the IEEE. These
reserved multicast addresses are identified by the Layer 2 destination MAC addresses. The multicast
addresses that support transparent transmission range from 0180:C200:0000 to 0180:C200:FFFF in this
document. If these addresses conflict with those of the 802.1X frames, the addresses in the 802.1X
frames are prior to use.
PVST frames: Cisco’s spanning tree protocol frames. These frames are identified by the destination MAC
address 0100:0CCC:CCCD.
Configuring Transparent Transmission of Protocol Frames
The default setting of transparent transmission of protocol frames are listed below. When the relevant
protocol is disabled, these protocol frames are regarded as Layer 2 multicast addresses.
