[mrtg] DHCP Sessions not returning via snmpget

[Jeff Daugherty]

Hello,

This is my first post so if im doing something wrong please let me know.

I have a number of Juniper 1440 and 320s in MRTG. On the same server i'm
trying to retrieve the PPPOE and DHCP sessions via snmpget. I know this is
infromation MRTG is currently polling from these devices but I need them for
a different report. The PPPOE (.1.3.6.1.4.1.4874.2.2.11.1.7.2.0) is an
integer type and works fine. However, the DHCP
(.1.3.6.1.4.1.4874.2.2.22.1.3.1.2.0) type is a Counter32 and returns the
following error:

snmpget -v 2c -c <COMMUNITY STRING> <DEVICE IP ADDRESS> AGENT OID
.1.3.6.1.4.1.4874.2.2.22.1.3.1.2.0

SNMPv2-SMI::enterprises.4874.2.2.22.1.3.1.2.0 = No Such Instance currently
exists at this OID
I got both of these oids from MRTG (via the SNMP Check link). Is there
another oid i should be trying to use or is there something special that
needs to be done to poll a counter32 oid?

Any help or input would be greatly appreciated!
