I've monitoring some Cisco Catalyst Switch, whats'up received the traps, the map change color but nothing is display on trap name.  

The following is an example (the trap should be linkdown)

%a=10.10.20.11

%u=EVENT SNMP Trap/Unsolicited

%m= Int:1 ****

%(CommunityName)=****

%(EventName)=Unsolicited

%(EventType)=SNMP Trap

%(LogicalSource)=0.0.0.0

%(Object)=

%(PhysicalSource)=10.10.20.11

%(Timetick)=:1 ****

%(TrapMajor)=9999

%(TrapMinor)=0

%(TrapName)=

What's the problem?

Thank you for your help!
