Configuring IEEE 802.1Q Tunneling

E XAMPLE
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.
Figure 485: 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
