Configuring IPv4 Multinetting

You configure IP multinetting by adding a secondary IP address to a VLAN.

Use the following command to add a secondary IP address:
configure vlan vlan_name add secondary-ipaddress [ip_address {netmask} | ipNetmask]

After you have added a secondary IP address, you cannot change the primary IP address of a VLAN until you first delete all the secondary IP addresses.
To delete secondary IP addresses, use the following command:
configure vlan vlan_name delete secondary-ipaddress [ip_address | all]
