Port-Based VLAN Stacking Configuration Example
This section provides a tutorial for configuring the sample application, as illustrated on page 6-31, using
port-based VLAN Stacking. This tutorial assumes that both provider edge switches (PE1 and PE2) are
operating in the VLAN Stacking legacy mode.
Configure Port 1/1 as a User-Customer Port for Customer A on PE1 and PE2
Port 1/1 is a VLAN Stacking user-customer port that connects to customer A’s network. All BPDU pack-
ets ingressing on that port are to be tunneled on the SVLAN.
1 Create SVLAN 100 with a name using the vlan svlan command as shown in the example below:
-> vlan svlan 100 name "Customer A"
2 Configure port 1/1 as a user-customer port and assign SVLAN 100 as the default SVLAN for the port
using the vlan svlan port command as shown in the example below:
-> vlan svlan port 1/1 user-customer-port default-svlan 100
3 Configure port 1/1 to flood all BPDU packets ingressing on port 1/1 using the vlan svlan port bpdu-
treatment command as shown in the example below:
-> vlan svlan port 1/1 bpdu-treatment flooded
Configure Port 2/1 as a User-Customer Port for Customer B on PE1 and PE2
Port 2/1 is a VLAN Stacking user-customer port that connects to customer B’s network. All BPDU pack-
ets ingressing on that port are to be filtered/dropped. Packets tagged with CVLAN 10 are to be tunneled
using SVLAN 200. Other VLAN-tagged packets are to be dropped.
1 Create SVLAN 200 with a name using the vlan svlan command as shown in the example below:
-> vlan svlan 200 name "Customer B"
2 Configure port 2/1 as a user-customer and assign SVLAN 200 as the default SVLAN for the port using
the vlan svlan port command as shown in the example below:
-> vlan svlan port 2/3 user-customer-port default-svlan 200
3 Configure port 2/1 to drop all BPDU packets ingressing on the port using the vlan svlan port bpdu-
treatment command as shown in the example below:
-> vlan svlan port 2/1 bpdu-treatment dropped
4 Configure port 2/1 to accept only tagged frame types using the vlan svlan port accept-frame-type
command as shown in the example below:
-> vlan svlan port 2/1 accept-frame-type tagged
5 Associate SVLAN 200 with CVLAN 10 on port 2/1 using the vlan svlan port svlan command as
shown in the example below:
-> vlan svlan port 2/1 double-tag cvlan 10 svlan 200
6 Configure port 2/1 to drop packets ingressing on the port that trigger a VLAN lookup miss using the
vlan svlan port lookup-miss command as shown in the example below:
-> vlan svlan port 2/1 lookup-miss drop
