Have you found a solution to this problem? I'm about to monitor lots of pix 501s and would be nice to get the interface data! Someone mentioned that the pix cannot be monitored as it thinks it's under attack...
Could this somehow be the case?
I didn't think of that possibility.
I haven't been able to solve my problem at the moment... but all I can say is that I'm currently replacing my 501s and 506s with ASA 5505 and they work like a charm.
I'll check with the 506 I have left here in the office and let you know this later today.
EDIT : If I look at the syslog debug information on my 506, it doesn't drop anything regarding SNMP... I just think it's a bad implementation of SNMP in this IOS...
Changing poll to 30 sec doesn't change anything. The interfaces still appear and disappear. The odd thing is that you can get the graphics when you click on the link...
PLEASE... Release source code to the community and start developing The Dude again....
