Allied Telesis stacked switches problem

Hi,

I have got 2 AT-9448s/XP switches configured in a stack, where one of them is having a role as master while other is member.

In Oputils 5, on switch port mapper, it shows only 48 ports, and it should map all 96 ports from both switches.

Also, Oputils groups by the hosts from desired port on both switches.

Example: on port 1.2 I have 2 hosts (host a, and host b), and on port 2.2 I have 3 hosts (host c, host d, host e). On Switch port mapper I can find 5 hosts under port 2. Which means that it recognized hosts from both switches, but did not distinct these two ports as separate ones.

Do you have any idea what might help me here?

Thanks,

Srecko
