snmpwalk -v 1 -c <community> <target-host> .1.3.6.1.2.1.2.2.1.2 -Oqn
This will print a bunch of strings looking something like this (taken 
from a Cisco 1605R);
.1.3.6.1.2.1.2.2.1.2.1 Ethernet0
.1.3.6.1.2.1.2.2.1.2.2 Ethernet1
.1.3.6.1.2.1.2.2.1.2.3 Null0
.1.3.6.1.2.1.2.2.1.2.4 Loopback0
.1.3.6.1.2.1.2.2.1.2.5 Tunnel1

The first part is the OID. The second part is the interface description.
The last section (the part after the last dot) of the OID is the 
interface index number. This is what you need to pass to check_traffic.

Note that on some particularly evil devices, the interface index number 
can change after a reboot. If you get some really weird values, this 
might be the case for you.
