Interconnect ports on FAS3240 / N6240 (IBM)

We have a FAS3240 (IBM N6240 actually) and are wanting to trunk in a
network and give ourselevs a new vif on subnet 192.168.3.0/24 (as an
example).

However, we see that the interconnect interfaces (c0a/c0b) have an IP
in this same range (192.168.3.x). It seems as those these are internal
only, and as such I'm guessing if we add a vif for serving data in the
same subnet, there won't be any conflicts?

Can anyone confirm?

Thanks,
Ray

This is covered in one of the FAQ/SE tech presos on field portal. Can't remember which one, but it was pretty easy to find.

Whoops, didn't notice I was responding externally. From the tech FAQ:

WHAT HAPPENS IF A CUSTOMER WANTS TO USE THE SAME TCP/IP ADDRESSES AND SUBNET AS THE HA PORTS ARE USING?
The on-board HA ports have their own private IP space along with their own routing table. Given this, other Ethernet ports on the FAS/V3200 can use the same subnet and addresses as the HA ports without any issues.

Sorry for the confusion!

Peter

Thanks for the pointer, Peter. Had missed this, but makes perfect
sense.
