Configuring IEEE 802.1Q Tunneling

20

Example

This example sets the SVID to 99 in the outer tag for egress packets exiting port 1 when the
packet’s CVID is 2.

Console(config)#interface ethernet 1/1

Console(config-if)#switchport dot1q-tunnel service 99 match cvid 2

Console(config-if)#

The following example maps C-VLAN 10 to S-VLAN 100, C-VLAN 20 to S-VLAN 200 and C-VLAN 30
to S-VLAN 300 for ingress traffic on port 1 of Switches A and B.

Mapping QinQ Service VLAN to Customer VLAN

Step 1. Configure Switch A and B.

1. Create VLANs 100, 200 and 300.

Console(config)#vlan database

Console(config-vlan)#vlan 100,200,300 media ethernet state active

2. Enable QinQ.

Console(config)#dot1q-tunnel system-tunnel-control

3. Configure port 2 as a tagged member of VLANs 100, 200 and 300 using uplink mode.

Console(config)#interface ethernet 1/2

Console(config-if)#switchport allowed vlan add 100,200,300 tagged

Console(config-if)#switchport dot1q-tunnel mode uplink

4. Configures port 1 as an untagged member of VLANs 100, 200 and 300 using access mode.

Console(config)#interface ethernet 1/1

Console(config-if)#switchport allowed vlan add 100,200,300 untagged

Console(config-if)#switchport dot1q-tunnel mode access

5. Configure the following selective QinQ mapping entries.

Console(config)#interface ethernet 1/1

Console(config-if)#switchport dot1q-tunnel service 100 match cvid 10

Console(config-if)#switchport dot1q-tunnel service 200 match cvid 20

Console(config-if)#switchport dot1q-tunnel service 300 match cvid 30

6. Configures port 1 as member of VLANs 10, 20 and 30 to avoid filtering out incoming frames

tagged with VID 10, 20 or 30 on port 1

Console(config)#interface ethernet 1/1

Console(config-if)#switchport allowed vlan add 10,20,30
