I had a problem with sonicwall's XPRS2 firewall a few years ago.
Although they said they supported SNMP, their counters didn't seem to do
It took several firmware updates (about a year's worth) before they
decided to fix this, which was highly annoying.

Could this be the case with yours?

Another problem I have come across with devices is a Netgear GS724T
switch, which logs traffic properly for about a week or so, then seems
to give up.
After a power cycle, it starts logging again. Very annoying. We were
thinking of replacing all our switches with this model, but I'm not
going to bother now.

It seems that not everyone can implement SNMP properly....
