SNMP Continued

I worked with LT on the SNMP issue for about an hour, but was not able to get it resolved.  At this point I am not sure if it is our testing methodology or LT.  LT has been making changes to the SNMP Trap monitoring, so this could just be some side-effects of being on a release candidate.

For anyone that is interested, there is a good tool out there for sending SNMP traps.  It is called TrapGen and is a free download from NCT.

To send a trap to a trap receiver, you simply use the command TRAPGEN -D xxx.xxx.xxx.xxx .

It will send a static SNMP trap to the device and is very useful for testing.  You can override the static trap info by using additional command line options.

I also did some packet captures to identify the SNMP traffic to ensure that it was being formatted correctly.
