Pro Curve 8212zl secondary subnet on a vlan

[gschneegass]

Is it possible to add a secondary subnet to a vlan interface. If so what would be the command structure? It is possible on Cisco by giving you secondary option, not seeing that type of option on HP.

Hello,

A VLAN that can have IP interfaces in different IP subnets is called multinetted VLAN.

See this document.

Multinetting: Assigning Multiple IP Addresses to a VLAN.

For a given

VLAN you can assign one primary IP address and up to seven secondary IP

addresses. This allows you to combine two or more subnets on the same

VLAN, which enables devices in the combined subnets to communicate

normally through the network without needing to reconfigure the IP addressing

in any of the combined subnets.

The exact configuration is explained on page 8-9 but it is really straightforward.

Correction: The 8212zl supports 32 IP addresses per VLAN
