Hi John,
To dump the cache information on 9.2.1, you can use the following action codes. You may need to run these on BOTH the trap directory and/or the remote box depending on what you are looking for.
0x00010247
This action will dump the alert tables, so that you can check which trap OIDs are registered for (by what model types), which events are generated for them, and which varbinds will be included
0x00010248
This action will show you which IP addresses are registered for, so you will be able to check on which model(s) traps from these addresses will end up.
0x0001011c
This action will dump statistics about remote models found during trap/event forwarding, and counters about how many items were forwarded to them.
0x00010291
Dump alert manager statistics, like how many traps received/processed, plus some more counters covering remote trap forwarding
In Spectrum 9.2.3 and above, you can actually turn on the Alert Manager Debug via the Dynamic Debugging on the VNM and you can print the contents of the cache from the Trap Management subview off the VNM:
Hope that helps
Jay
