Chapter 38. Layer 2 Tunnel Protocol
Configuration
Configuring Layer-2 Protocol Tunnel
38.1
38.1.1 Introduction
Layer-2 protocol tunnel allows users between two sides of the switch to transmit the specified layer 2 protocol
on their own network without being influenced by the relevant layer 2 software module of the switch. The
switch is a transparent media for users.
38.1.2 Configuring Layer-2 Protocol Tunnel
Use the command line on the interface of the switch to configure tunnel function of the layer 2 protocol. The
configuration steps are as follows:
Command Description
configure Enters global configuration mode.
interface <intf_name>
Enters interface configuration mode of the switch.
Only the switch port supports layer 2 protocol
tunnel (including physical port and aggregation
port).
[no] l2protocol-tunnel [stp]
Enables layer 2 protocol of the tunnel function.
Currently we only support tunnel function of stp
protocol.
[CTRL] + Z Returns to EXEC mode.
write Saves configuration.
38.1.3 Configuration Example of Layer 2 Protocol Tunnel
Network environment is as follows:
C1 C2
GatherA1 A2
F0/1
F0/2F0/1
F0/1
F0/1
F0/1
F0/2
F0/2
A1/A2/Gather belong to core network, C1/C2 are switches distributed in two places. Customer wants to
combine two of its network to one , that is, the core network is a transparent transmission channel for the
customer. If user wants to realize the transparent transmission of STP, then the following configurations
should be configured on each switch:
