[Nagiosplug-help] check_snmp_int.pl on a cisco 6500

Thanks for replying so fast. What I'd like to do exactly is to monitor
(and get and alert) when an interface goes down or comes up.

I've played a little with the switches and I found that this works:

[root at ccc-nagios plugins]# ./check_snmp_int.pl -H 10.0.0.X -C string -n

1 :DOWN, A :UP, 14:DOWN, CPU:UP, 20:UP, 16:DOWN, 18:DOWN, 12:DOWN,
17:DOWN, PortChannel:DOWN, 3 :DOWN, AUI:UP, 2 :DOWN, 19:DOWN, 22:DOWN, 7
:DOWN, 9 :DOWN, 13:DOWN, 23:DOWN, 6 :DOWN, 4 :DOWN, B :DOWN, 10:UP,
15:DOWN, 21:UP, 8 :DOWN, 24:DOWN, 5 :DOWN, 11:UP: 22 int NOK : CRITICAL

Now, how do I include it into the files and which files? I'm guessing
probably service.cfg and checkcommands.cfg? Am I on the right track
considering my goal? Thanks.

 From the output you can see that you need to provide a "-n <name in
desc_oid>" Check the help for 
more info.

If you only want to check if a specific interface is up a check like:

$USER1$/check_snmp -H $HOSTADDRESS$ -C $USER3$ -P 1 -o
. -w 1:1 -c 1:1

Replace X with your Port to check (is the numeric oid for
IF-MIB::ifOperStatus.X) it will return ok 
if the port is up and critical if the port is down.
