What would cause a MIB walk to stop before all the interfaces have been found?

[John_W]

I'm using a template that has 24 actions. One of them is just called "SNMP walk Network Interfaces" . The walk includes a handful of OIDs. The issue is when I use this template on a switch with 48 ports, it only discovers 24. It finds all types of ports on the switch, but never past the ones named x/x/24.

What would cause this?

Some more info:

If I go to Monitoring -> Latest Data the tags show all the ports. However, if I scroll through all the data below the tags it still stops after 24 ports. If I check the Host -> Items from any menu it shows me only 24 ports.
