Configuration Guide - Ethernet Switching

S7700 and S9700 V200R011C10

This document describes the configuration of Ethernet services, including configuring link aggregation, VLANs, Voice VLAN, VLAN mapping, QinQ, GVRP, MAC table, STP/RSTP/MSTP, SEP, and so on.

(Optional) Enabling Proxy ARP on the VLANIF Interface Corresponding to a Super-VLAN


VLAN aggregation allows sub-VLANs to use the same subnet address, but prevents PCs in different sub-VLANs from communicating with each other over Layer 3.

PCs in common VLANs can communicate with each other over Layer 3 using different gateway addresses. VLAN aggregation enables PCs in a super-VLAN to use the same subnet address and gateway address. Because PCs in different sub-VLANs belong to one subnet, they can only communicate with PCs in their sub-VLAN. PCs in different sub-VLANs cannot communicate with each other.

Proxy ARP is required to enable PCs in a sub-VLAN to communicate with PCs in another sub-VLAN or PCs on other networks. After a super-VLAN and its VLANIF interface are created, proxy ARP must be enabled to allow the super-VLAN to forward or process ARP Request and Reply packets.


After proxy ARP is enabled on the VLANIF interface corresponding to a super-VLAN, PCs in all sub-VLANs of the super-VLAN can communicate. If PCs in some sub-VLANs of the super-VLAN need to communicate, see How Do I Implement Communication Between Specific Sub-VLANs in a Super-VLAN.

VLAN aggregation simplifies configurations for networks where many VLANs are configured and PCs in different VLANs need to communicate with each other.


  1. Run system-view

    The system view is displayed.

  2. Run interface vlanif vlan-id

    The view of the VLANIF interface corresponding to the super-VLAN is displayed.

  3. Run arp-proxy inter-sub-vlan-proxy enable

    Proxy ARP is enabled between sub-VLANs.
