use check_ifoperstatus for individual interfaces (one service for each 
interface)

Before you start - you need to run snmpwalk on the routers and get the 
ifIndex values for the interfaces you are interested in. Then supply the 
value to the -k parameter of check_ifoperstatus. Also be sure to have the 
IOS configuration nail down the ifIndex values...
"snmp-server ifindex persistent"

If you were interested in monitoring "all" the admin up interfaces on a 
router, then you can use "check_ifstatus" instead.  It covers all 
interfaces that are supposed to be up - summary results report 
up/down/dormant interfaces.
