Does check_ifoperstatus (part of nagios-plugins) not do what you need?

Here's an example against a BNT switch, but IF-MIB is standard, it
should work just fine against a Cisco:

- Using ifIndex:

  $ /usr/lib64/nagios/plugins/check_ifoperstatus -H bntsw1 -k 145
  OK: Interface EXT1 (index 145) is up.
  $ 

- Using ifDescr:

  $ /usr/lib64/nagios/plugins/check_ifoperstatus -H bntsw1 -d EXT1
  OK: Interface EXT1 (index 145) is up.
  $ 

- against a down port:

  $ /usr/lib64/nagios/plugins/check_ifoperstatus -H bntsw1 -d INT6A
  CRITICAL: Interface INT6A (index 139) is down.
  $ 

- ifOperStatus:

  $ snmpget -v 2c -c <somecommunity> bntsw1 ifOperStatus.145
  IF-MIB::ifOperStatus.145 = INTEGER: up(1)
  $ snmpget -v 2c -c <somecommunity> bntsw1 ifOperStatus.139
  IF-MIB::ifOperStatus.139 = INTEGER: down(2)
  $ 

This is on a CentOS 5.x box with nagios-plugins-1.4.15-2.el5.rf from
RPMforge.
