Limit on number of Virtual IP's attached to an interface?

[Adam Garsha]

Bandwidth utilization aside, is there a hard-limit on the number of Virtual IP's that can be tied to a single interface?

I am looking for any gotcha's with adding VIP #4.

Thanks.

As far as I know there is no limit on the number of virtual IP addresses that you can use on any given physical interface. Especially in such low number of 4th 5th and so on

I think you can use 200+ VIP's

oh forgot to add that: only limitation is that all your IP addresses need to be on the same subnet. So, your limitation is not from hpux box but from the networking perspective.

Hi Adam

256 is the maxium amount of ip address that can be bound to a single nic

Hi Adam,

I agree with the posts above. The limits is not atleast upto 100 atleast. We have sometimes used upto 56 Virtual IP's on a single interface.

Does anyone know if the limit is still(?) 256 with 11.23?

Thanks.
