Hi, i have a problem when i want to monitoring a Cisco device (Switch 2960).
Qhen i configured Nagios, never show the CRITICAL state, when the port /
interface is down, because always receibe a message for SNMP, that it´s Ok.

Doing a research, i see this. When i use the terminal of Linux Server the
command with the string that use Nagios "hardcoded" vía snmp the devide send
me this message, and nagios don´t know how understand this.

root at NAGIOS:# /usr/local/nagios/libexec/check_snmp -C COMUNIDAD -o
ifOperStatus.10001 -r 1 -m RFC1213-MIB -H IP_HOST

If the interface it´s Ok:
SNMP OK - 1 | RFC1213-MIB::ifOperStatus.10001=1

But if the interface is down:
SNMP OK - 2 | RFC1213-MIB::ifOperStatus.10002=2

So, i understand the 1 is "Ok" and the 2 id "down", how evener, nagios
understand "ok" in both cases.

Thanks in advance for the help, and sorry for my english.
