DES-7200 Configuration Guide Chapter 6 Super VLAN Configuration
6-7
6.8.3 Configuration tips
1. Achieve layer-2 isolation on access switches (Switch B, Switch C and
Switch D) through VLAN division (VLAN 10, VLAN 20 and VLAN 30).
2. Configure Super VLAN (VLAN 2) on the convergence device (Switch A),
and configure the VLANs (VLAN 10, VLAN 20 and VLAN 30) to
Sub-VLANs on the access device.
3. Configure SVI (192.168.1.1/24) for Super VLAN, and assign IP address
ranges for respective Sub-VLANs (as shown above).
6.8.4 Configuration Steps
The following configurations are performed on Switch A; VLAN divisions on
Switch B, Switch C and Switch D won't be further described.
z Configure Switch A
Step 1: Enter the global configuration mode and create VLAN 2, VLAN 10,
VLAN 20 and VLAN 30.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)#vlan 2
DES-7200(config-vlan)#exit
DES-7200(config)#vlan 10
DES-7200(config-vlan)#exit
DES-7200(config)#vlan 20
DES-7200(config-vlan)#exit
DES-7200(config)#vlan 30
DES-7200(config-vlan)#exit
Step 2: Configure VLAN 2 as the Super VLAN; the corresponding Sub-VLANs
are VLAN 10, VLAN 20 and VLAN 30.
DES-7200(config)#vlan 2
DES-7200(config-vlan)#supervlan
DES-7200(config-vlan)#subvlan 10,20,30
DES-7200(config-vlan)#exit
Step 3: Configure the corresponding layer-3 virtual interface for Super VLAN 2,
and users belonging to Sub-VLANs associated to Super VLAN 2 will achieve
layer-3 communication through this interface.
DES-7200(config)#interface vlan 2
DES-7200(config-if-VLAN 2)#ip address 192.168.196.1 255.255.255.0
Step 4: Configure the IP address range of 192.168.196.10-192.168.196.50 for
Sub-VLAN 10, 192.168.196.60-192.168.196.100 for Sub-VLAN 20, and
192.168.196.110-192.168.196.150 for Sub-VLAN 30.
