Step Command Remarks
1. Enter system view. system-view N/A
2. Create a VLAN interface, and
enter VLAN interface view.
interface vlan-interface
vlan-interface-id The value of vlan-interface-id must
be the ID of the super VLAN.
3. Configure the IP address of
the VLAN interface. ip address ip-address { mask |
mask-length } [ sub ]
By default, the IP address of a
VLAN interface is not configured.
This step configures an IP address
for the VLAN interface
corresponding to the super VLAN.
4. Enable local proxy ARP. local-proxy-arp enable
By default, local proxy ARP is
disabled.
For more information about the
local proxy ARP function, see Layer
3—IP Services Configuration
Guide. For more information about
the local-proxy-arp enable
command, see Layer 3—IP
Services Command Reference.
Displaying and maintaining super VLAN
Task Command Remarks
Display the mapping between a
super VLAN and its sub-VLANs.
display supervlan [ supervlan-id ] [ |
{ begin | exclude | include }
regular-expression ]
Available in any view.
Super VLAN configuration example
IMPORTANT:
By default, Ethernet interfaces, VLAN interfaces, and aggregate interfaces are in DOWN state. Before
configuring these interfaces, use the undo shutdown command to bring them up.
Network requirements
As shown in Figure 10 :
• Create super VLAN 10, and configure its VLAN interface IP address as 10.0.0.1/24.
• Create the sub-VLANs VLAN 2, VLAN 3, and VLAN 5.
• Assign GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2 to VLAN 2, GigabitEthernet 3/0/3
and GigabitEthernet 3/0/4 to VLAN 3, and GigabitEthernet 3/0/5 and GigabitEthernet 3/0/6
to VLAN 5.
• The sub-VLANs are isolated at Layer 2 but connected at Layer 3.
