Chapter 8 Configuring IEEE 802.1Q Tunneling and Layer 2 Protocol Tunneling on the ML-Series Card

Configuring IEEE 802.1Q Tunneling

	Command	Purpose
Step 4
Step 4	ML_Series(config-if)# bridge-group	Assigns the tunnel port to a VLAN. All traffic from the port (tagged
	vlan-number	and untagged) will be switched based on this bridge-group. Other
		members of the bridge-group should be VLAN subinterfaces on a
		provider trunk interface.
Step 5
Step 5	ML_Series(config-if)# mode	Sets the interface as an IEEE 802.1Q tunnel port to enable QinQ.
	dot1q-tunnel
Step 6
Step 6	ML_Series(config)# end	Returns to privileged EXEC mode.
Step 7
Step 7	ML_Series# show dot1q-tunnel	Displays the tunnel ports on the switch.
Step 8
Step 8	ML_Series# copy running-config	(Optional) Saves your entries in the configuration file.
	startup-config

Note The VLAN ID (VID) range of 2 to 4095 is recommended for IEEE 802.1Q tunneling on the ML-Series card.

Note If VID 1 is required to be used as a metro tag, use the VLAN dot1Q tag native global configuration command.

Use the no mode dot1q-tunnelinterface configuration command to remove the IEEE 802.1Q tunnel from the interface.

The following examples show how to configure the example in Figure 8-1 on page 8-2. Example 8-1applies to ML_Series A, and Example 8-2applies to ML_Series B.
