I'm trying to use Cacti to monitor several SSGs and an ISG, and I've come across an issue with subinterfaces on the ISG.
I created a host template here that works great for the SSG series. I can monitor VPN tunnels, subinterfaces, etc. However, when I try to apply the same template to the ISG, the values are all wrong. I notice that when I snmpwalk the ISG the interfaces only increment up to .7 (i.e. ifInOctets.1-7) when this device has at least 14 subinterfaces.
I've attached graphs between two interconnected interfaces on an ISG and an SSG. Traffic should be inversely mirrored on these graphs, but the ISG graph just seems to be all wrong. The SSGs are all running 6.1 and the ISG is running 6.0. Is there something different between the two hardware platforms or is the difference in the ScreenOS version or both that would be causing this?
