Super Vlan Configuration; Configuring Super Vlan - HP 5820X series Configuration Manual

Super VLAN configuration

Super VLAN, also called "VLAN aggregation," was introduced to save the IP address space.
A super VLAN is associated with multiple sub-VLANs. Create a VLAN interface for a super VLAN and
assign an IP address for the VLAN interface. However, you cannot create a VLAN interface for a sub-
VLAN. Assign a physical port to a sub-VLAN, but not to a super VLAN. All ports of a sub-VLAN use the
VLAN interface IP address of the associated super VLAN. Packets cannot be forwarded between sub-
VLANs at Layer 2.
To enable Layer 3 communication between sub-VLANs, create a super VLAN and the VLAN interface,
and enable local proxy ARP or local proxy ND on the VLAN interface depending on the VLAN interface
IP address type (IPv4 or IPv6) as follows:
In an IPv4 network, enable local proxy ARP on the VLAN interface. The super VLAN can use local
•
proxy ARP to forward and process ARP requests and replies.
In an IPv6 network, enable local proxy ND on the VLAN interface. The super VLAN can use local
•
proxy ND to forward and process the NS messages and NA messages.

Configuring super VLAN

To configure super VLAN, complete the following tasks:
Configure sub-VLANs.
1.
Configure a super VLAN, and associate the super VLAN with the sub-VLANs configured earlier.
2.
Configure a VLAN interface for the super VLAN. The VLAN interface enables communication
3.
among hosts and sub-VLANs.
Configuring sub-VLANs
To configure a sub-VLAN:
To do...
1. Enter system view
2. Create a sub-VLAN and enter
VLAN view
To configure more sub-VLANs, repeat these steps.
Configuring a super VLAN
To configure a super VLAN:
To do...
1. Enter system view
2. Enter VLAN view
Use the command...
system-view
vlan vlan-id
Use the command...
system-view
vlan vlan-id

Remarks
—
Required.
If the specified VLAN already exists,
this command enters VLAN view only.
Remarks
—
Required.
If the specified VLAN does not exist,
this command creates the VLAN first,
and then enters VLAN view.
