IP configuration on HP 11

[Daniel Fourie]

I would like to know how can I configure one IP addresses on HP-UX11 with two network cards. Meaning that the two network cards must have the same IP address [ Floating address ]

Hi Daniel:

Have a look at the Auto-Port Aggregation Software product for this:

Hi daniel,

IF you are asking this question for bandwidth reasons, yes then you have to look at Auto port aggregation.

But if you are asking from MC-Service Guard perspective, where the packagage IP address (floating address) gets assigned to primary/standby NICs then its the MC/SG software which takes care of it.

For more information on MC/SG check

Hello Daniel,

and if you want a floating ip-address without MC/SG, then you have to use commands like
ifconfig lan0:1 1.2.3.4 up
to add the address (1.2.3.4 in this example) and
ifconfig lan0:1 0.0.0.0 down
to get rid of it.

AND make damn sure you NEVER EVER have it active concurrently!!!!!!

HTH,

Sounds like you want Autoport Aggregation. Unfortunately, its an optional addon, i.e. costs money...roughly $1,000 per server.

If you want those two interfaces to behave as one, the suggestions to get APA are the way to go.

It is possible to assign an alias to the lo0 interface. This is done for virtual IP support behind some load balancers. Not sure if that is what you were talking about but thought I'd mention it.

There isn't any other way than APA to achieve what you need.

However, there are some limitations on the equipment that the Auto Port Aggregation is supported. Check this release notes before you go further.
