[cacti-user] Using Cacti to SNMP query a Cisco

[elsif <ja...@el...>]

I'm trying to query a Cisco 5300 for total ports in use.

The object ID for this is: .1.3.6.1.4.1.9.10.19.1.1.3

An SNMPwalk completes fine...
cacti:/home/cactiuser/public_html/scripts# snmpwalk -v2c -c <snip> 209.197.<snip> .1.3.6.1.4.1.9.10.19.1.1.3
SNMPv2-SMI::enterprises.9.10.19.1.1.3.0 = Gauge32: 20

Yet for some reason, when I try to graph this I get no data, and my graph 
items are all N/A.

So my questions are, I guess, as follows:

I see no obvious errors in the cacti.log for this host.  What should I be 
looking for?

Is there some other secret to getting certain Cisco OID's to work 
properly?

Thanks all,
-Jake
