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 192.201.3.1/24
    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.
