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.

Configuring Q-in-Q Tunnels and Layer 2 Protocol Tunneling
Purpose
Enters global configuration mode.
Specifies a global CoS value on all Layer 2 protocol
tunneling ports. The default cos-value is 5.
(Optional) Sets the global CoS value to default.
Exits configuration mode.
(Optional) Copies the running configuration to the
startup configuration.
