157Step Command Remarks1. Enter system view. system-view N/A2. Enter VLAN view. vlan vlan-id If the VLAN does not exist, this command creates theVLAN and leads into VLAN view.3. Configure the VLAN as asuper VLAN. supervlan By default, a VLAN is not a super VLAN.4. Associate the super VLANwith the specified subVLANs.subvlan vlan-id-listBy default, a super VLAN is not associated with anysub VLANs.Make sure the sub VLANs already exist beforeassociating them with a super VLAN.Configuring a super VLAN interfaceH3C recommends not configuring VRRP for the VLAN interface of a super VLAN, because theconfiguration affects network performance. For more information about VRRP, see High AvailabilityConfiguration Guide.To configure a VLAN interface for a super VLAN:Step Command Remarks1. Enter system view. system-view N/A2. Create a VLANinterface and enter itsview.interface vlan-interfacevlan-interface-idThe vlan-interface-id argument must bethe super VLAN ID.3. Configure an IPaddress for the VLANinterface of the superVLAN.• Configure an IPv4 address:ip address ip-address{ mask-length | mask } [ sub ]• Configure an IPv6 address:ipv6 address { ipv6-addressprefix-length |ipv6-address/prefix-length }By default, no IP address is configuredfor a VLAN interface.4. (Optional.) ConfigureLayer 3 communicationbetween sub VLANs.• Enable local proxy ARP for devicesthat run IPv4 protocols:local-proxy-arp enable• Enable local proxy ND for devicesthat run IPv6 protocols:local-proxy-nd enableBy default:• Sub VLANs cannot communicatewith each other at Layer 3.• Local proxy ARP or ND is disabled.For more information about localproxy ARP and proxy ND functions,see Layer 3—IP Services ConfigurationGuide.For more information aboutlocal-proxy-arp enable andlocal-proxy-nd enable commands, seeLayer 3—IP Services CommandReference.
