Can't monitor Up/Down port state with Prime Infrastructure3.1

[petpkcui1]

Hi everyone

I've problem with  Cisco Prime Infrastructure 3.1 . When a port of a switch goes down, the cisco Prime Infrastructre doesn't generates  Critical Alarm for that (this is a problem happen with all port) although Interface alarm policy is set by default (generates for all devies and group).

Please help me fix this issue.

Tks all

 - Check, wether you have log forwarding and snmp trap forwarding set to cisco prime (also) for the particular set of switches.

  - The latter are configuration changes which must be applied on the switches ; such as for instance:

                logging host ip-address-of-prime-server

               snmp-server host ip-address-of-prime-server

If  you are not familiar with these (IOS)  commands ; study there documentation first

But i think my problem isn't snmp. Because i can still monitor devices with though snmp (include reachability, snmp status)

  - That is true, but my suggestions still apply ; the notification forwarding makes prime aware of an issue otherwise prime would need continuous polling about interfaces statuses to generate correct notifications which would be a burden both for prime and the switches (in resource terms).. Hence the notification forwarding for the discussed components (snmp traps , and syslogging) from the switches -> Prime is still needed.
