Chapter 9 Configuring Q-in-Q VLAN Tunnels
Configuring Q-in-Q Tunnels and Layer 2 Protocol Tunneling
DETAILED STEPS
This example shows how to specify a global CoS value for the purpose of Layer 2 protocol tunneling:
switch# configure terminal
switch(config)# l2protocol tunnel cos 6
switch(config)# exit
Configuring the Rate Limit for Layer 2 Protocol Tunnel Ports
You can specify the hardware rate limiter configuration for Layer 2 protocol tunneling. The default is set
to 500 packets per second. Depending on the load or the number of VLANs to be tunneled for a customer,
you may need to adjust this value to prevent STP errors on the customer’s network.
SUMMARY STEPS
1. configure terminal
2. hardware rate-limiter layer-2 l2pt packets-per-sec
3. no hardware rate-limiter layer-2 l2pt
Command Purpose
Step 1
configure terminal
Example:
switch# configure terminal
Enters global configuration mode.
Step 2
l2protocol tunnel cos cos-value
Example:
switch(config)# l2protocol tunnel cos 6
Specifies a global CoS value on all Layer 2 protocol
tunneling ports. The default cos-value is 5.
Step 3
no l2protocol tunnel cos
Example:
switch(config)# no l2protocol tunnel cos
(Optional) Sets the global CoS value to default.
Step 4
exit
Example:
switch(config)# exit
Exits configuration mode.
Step 5
copy running-config startup-config
Example:
switch# copy running-config startup-config
(Optional) Copies the running configuration to the
startup configuration.
