Usage Guidelines

Adding a secondary IP address to a VLAN enables multinetting. Secondary addresses are added to support legacy stub IP networks.

Once you have added a secondary IP address to a VLAN, you cannot unconfigure the primary IP address of that VLAN until you delete all the secondary addresses. Delete secondary address with the following command:

configure [ {vlan} vlan_name |vlan vlan_id] delete secondary-ipaddress [ip_address | all]

Example

The following example configures the VLAN multi to support the 10.1.1.0/24 subnet in addition to its primary subnet:

configure vlan multi add secondary-ipaddress 10.1.1.1/24
