The follow example illustrates how to configure VLAN aggregation. The VLAN vsuper
is created as a super-VLAN, and sub-VLANs, vsub1, vsub2, and vsub3 are added to it.
1 Create and assign an IP address to a VLAN designated as the super-VLAN. This
VLAN should have no member ports. Be sure to enable IP forwarding, and any
desired routing protocol, on the switch.
create vlan vsuper
config vsuper ipaddress 192.201.3.1/24
enable ipforwarding
enable ospf
config ospf add vsuper
2 Create and add ports to the sub-VLANs.
create vlan vsub1
con vsub1 add port 10-12
create vlan vsub2
config vsub2 add po 13-15
create vlan vsub3
config vsub3 add po 16-18
3 Configure the super-VLAN by adding the sub-VLANs.
config vsuper add subvlan vsub1
config vsuper add subvlan vsub2
config vsuper add subvlan vsub3
4 Optionally, disable communication among sub-VLANs.
disable subvlan-proxy-arp <super-VLAN name>

The following commands can be used to verify proper VLAN aggregation
configuration.
•
show vlan
— Indicates the membership of a sub-VLANs in a super-VLAN.
•
show iparp
— Indicates an ARP entry that contains sub-VLAN information.
Communication with a client on a sub-VLAN must have occurred in order for an
entry to be made in the ARP table.
