I am monitoring a Cisco 2960G switch with Nagios. I am getting green (OK) for ping, port 1 link status and uptime. Port 3 link status is orange with the error: SNMP problem  No data received from host. If I unplug the network cable in port 1 on the switch the port stays green in Nagios so it is not monitoring port 1.  The switch has an IP address on the vlan and SNMP is enabled read only. What do I have configured wrong?
define host{

	use		generic-switch		; Inherit default values from a template

	host_name	switch			; The name we're giving to this switch

	alias		Cisco Switch		; A longer name associated with the switch

	address		10.100.10.8		; IP address of the switch

	hostgroups	switches		; Host groups this switch is associated with
 

	}
 

define hostgroup{

	hostgroup_name		switches

	alias			Network Switches

	members			netware1,netware2,netware3,netware4

	}
 
 

define service{
 

	use			generic-service	; Inherit values from a template

	host_name		switch		; The name of the host the service is associated with

	service_description	PING		; The service description

	check_command		check_ping!200.0,20%!600.0,60%	; The command used to monitor the service

	normal_check_interval	5		; Check the service every 5 minutes under normal conditions

	retry_check_interval	1		; Re-check the service every minute until its final/hard state is determined
 

	}
 
 

define service{
 

	use			generic-service	; Inherit values from a template

	host_name		switch

	service_description	Uptime	

	check_command		check_snmp!-C public -o sysUpTime.0
 

	}
 
 

define service{
 

	use			generic-service	; Inherit values from a template

	host_name		switch

	service_description	Port 1 Link Status

	check_command		check_snmp!-C public -o ifOperStatus.1 -r 1 -m RFC1213-MIB
 

	}
 

define service{
 

	use			generic-service	; Inherit values from a template

	host_name		switch

	service_description	Port 2 Link Status

	check_command		check_snmp!-C public -o ifOperStatus.2 -r 1 -m RFC1213-MIB
 

	}

Used snmpwalk to find out correct interface. Command should be ifOperStatus.10101, ifOperStatus.10102, ifOperStatus.10103.
