SNMP Cisco Problem

[Jan Scholten]

Don't try to check the Admnin status (that is wheter the port is shutdown  
or no shutdown in the configs).

Try a snmpget -v 1 -c nagios 172.16.0.23 IF-MIB::ifOperStatus -w :1 -c:1
or if you have a different port to check on some routers:

# 'check_if_status' command definition
define command{
         command_name    check_if_status
         command_line    $USER1$/check_snmp -H $HOSTADDRESS$ -C $USER3$ -P  
1 -o .1.3.6.1.2.1.2.2.1.8.$ARG1$ -m ALL -l $ARG2$ -w $ARG3$ -c $ARG4$
         }
and call it with:check_snmp!1!Port Status for Port 1 is:!:1!:1

.1.3.6.1.2.1.2.2.1.8. is IfOperStatus (for the submittet Port $ARG1$)
$ARG2$ is a custom string
$ARG3$ and $ARG4$ are warning and critical ranges here it means : critical  
(as it has the same value as warning it will override warning) if Port  
Status is above. snmp returns 1 for up and 2 for down.

Hope that helps!
