Assigning An Ip Address To The Vlanif Interface Of A Super-Vlan; Optional) Enabling Proxy Arp On The Vlanif Interface Of A Super-Vlan - Huawei Quidway S7700 Configuration Manual - Ethernet

Quidway S7700 Smart Routing Switch
Configuration Guide - Ethernet
VLAN 1 cannot be configured as a super-VLAN.
Step 4 Run:
access-vlan { vlan-id1 [ to vlan-id2 ] } &<1-10>
A sub-VLAN is added to a super-VLAN.
Before adding sub-VLANs to a super-VLAN in batches, ensure that these sub-VLANs are not
configured with VLANIF interfaces.
The S7700 supports 256 sub-VLANs in a super-VLAN.

3.6.4 Assigning an IP Address to the VLANIF Interface of a Super-
VLAN
The IP address of the VLANIF interface of a super-VLAN must contain the subnet segments
where users in sub-VLANs reside. All the sub-VLANs use the IP address of the VLANIF
interface of the super-VLAN, thus saving IP addresses.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface vlanif vlan-id
A VLANIF interface is created for a super-VLAN, and the view of the VLANIF interface is
displayed.
Step 3 Run:
ip address ip-address { mask | mask-length } [ sub ]
An IP address is assigned to the VLANIF interface.

3.6.5 (Optional) Enabling Proxy ARP on the VLANIF Interface of a
Super-VLAN
PCs in different sub-VLANs cannot directly communicate with each other. To allow these PCs
to communicate with each other at Layer 3, enable proxy ARP on the VLANIF interface of the
super-VLAN.
Context
VLAN aggregation allows sub-VLANs to use the same subnet address, but prevents PCs in
different sub-VLANs from communicating with each other at the network layer.
PCs in ordinary VLANs can communicate with each other at the network layer by using different
gateway addresses. In VLAN aggregation, PCs in a super-VLAN use the same subnet address
and gateway address. As PCs in different sub-VLANs belong to one subnet, they communicate
