[mrtg] Packet monitoring construct - CISCO 3640

I'm attempting to expand our basic monitoring of our equipment. I'm running 
mrtg-2.9.10. What I want to do is to now monitor how many packets (not just 
bandwidth) that a particular router is dealing with (since we just had a 
packet limiting situation, this only makes sense :)

I basically took the "interface 2" definition and modified the Target line 
to reflect the OIDs I want to monitor. However, I don't seem to be having 
any luck. Here is the definition I generated:

### Interface 3 >> Descr: 'FastEthernet1/0' | Name: 'Fa1/0' | Ip: 
' | Eth: '00-02-fd-51-23-10' ###

MaxBytes[]: 1250000
Title[]: FastEthernet1/0 External to Qwest  -- 
PageTop[]: <H1>FastEthernet1/0 External to

    <TR><TD>Ip:</TD>         <TD> 

Additionally, since I am now monitoring packets and not bandwidth, are 
their any other "appicable" changes that should be made (such as, Max Speed 
or MaxBytes, which doesn't seem to be applicable, and the max packet value 
for the CISCO 3640 is someone of a guess).
