Chapter 8 Configuring IEEE 802.1Q Tunneling and Layer 2 Protocol Tunneling on the ML-Series Card
Configuring Layer 2 Protocol Tunneling
Configuring Layer 2 Tunneling Per-VLAN
Beginning in privileged EXEC mode, follow these steps to configure a VLAN as a Layer 2 tunnel
VLAN:
Monitoring and Verifying Tunneling Status
Table 8-3 shows the privileged EXEC commands for monitoring and maintaining IEEE 802.1Q and
Layer 2 protocol tunneling.
Command Purpose
Step 1
ML_Series# configuration terminal
Enters global configuration mode.
Step 2
ML_Series(config)# bridge
bridge-group-number
protocol
type
Creates a bridge group number and specifies a protocol.
Step 3
ML_Series(config)# l2protocol-tunnel
cos
cos-value
Associates a CoS value with the Layer 2 tunneling VLAN. Valid
numbers for cos-value range from 0 to 7.
Step 4
ML_Series(config)# interface
type
number.subinterface-number
Enters subinterface configuration mode and the subinterface to be
configured as a tunnel VLAN.
Step 5
ML_Series(config-subif)# encapsulation
dot1q
bridge-group-number
Sets the subinterface as an IEEE 802.1Q tunnel VLAN.
Step 6
ML_Series(config-subif)# bridge-group
bridge-group-number
Specifies the default VLAN, which is used if the subinterface stops
trunking. This VLAN ID is specific to the particular customer.
Step 7
ML_Series(config-subif)# end
Returns to privileged EXEC mode.
Step 8
ML_Series# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
