Hello
I'm out of Ip's in some VLAN and I want to add more ip's to the VLAN with adding more subnet to the VLAN.
In Cisco there is option to write for example:
vlan 10
ip add 10.7.4.1 255.255.252.0
ip add 10.7.76.1 255.255.252.0 secondary
the secondary gives the ability to combine few subnet in one vlan.
How i can make it in HP switches? I have procurve 5406.
note: i know that its not the best solution but i cant damage the vlan, i most increase the ip's in someway..
Multiple ip's in one vlan is not a new thing, but how i can do it in HP?
Thank you!

SolutionYou would simply enter:
vlan 10
ip add 10.7.4.1 255.255.252.0
ip add 10.7.76.1 255.255.252.0
Same funtionallity as Cisco, but you dont need to specify "secondary"
It's called Multinetting.
"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."
