VLAN Aggregation Example

The follow example illustrates how to configure VLAN aggregation. The VLAN vsuper is created as a superVLAN, and subVLANs, vsub1, vsub2, and vsub3 are added to it.

  1. Create and assign an IP address to a VLAN designated as the superVLAN. Be sure to enable IP forwarding and any desired routing protocol on the switch.
    create vlan vsuper
    configure vsuper ipaddress
    enable ipforwarding
    enable ospf
    configure ospf add vsuper area 0
  2. Create and add ports to the subVLANs.
    create vlan vsub1
    configure vsub1 add port 10-12
    create vlan vsub2
    configure vsub2 add port 13-15
    create vlan vsub3
    configure vsub3 add port 16-18
  3. Configure the superVLAN by adding the subVLANs.
    configure vsuper add subvlan vsub1
    configure vsuper add subvlan vsub2
    configure vsuper add subvlan vsub3
  4. Optionally, disable communication among subVLANs.
    disable subvlan-proxy-arp vlan all


    The above command has no impact on Layer 3 traffic.
