Hi All
I have setup up the Whatsup Professional to work with a Cisco Catalyst 2950.
the Catalyst is able to send SNMP trap and the Whatsup Professional is also able to receive the traps
however, it is found that the trap messages is changed in pattern all the time.
When I unplug and insert the one of the LAN connection, the debug message in SNMP report together with the pass out parameter %PassiveMonitor.Loggedtext is not fixed. please find below examples. You can find the pattern is not the same.
Is there any way to resolve?
