I have been trying for a couple of days now to get mrtg to give me graphs of
Channel Usage for my PRI's.  I have 8 PRI's in a Cisco 2821 Router.  I have
tried the following oid's to give me the graphs that I want:

1.3.6.1.4.1.9.10.19.1.1.9.1.3 

but I am not getting the value that I want.  I did do a snmpwalk within mrtg
and still no luck.  This is what it tells me:

E:\Mrtg\bin>snmpwalk -v1 -c xxxxxxxxx X.X.X.X 1.3.6.1.4.1.9.10.19.1.1.9.1.3
SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.3.0.0 = Gauge32: 6
SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.3.0.1 = Gauge32: 23

I have also tried 1.3.6.1.4.1.9.10.19.1.1.9.1 and this is what I get:

E:\Mrtg\bin>snmpwalk -v1 -c xxxxxxxxxxx X.X.X.X 1.3.6.1.4.1.9.10.19.1.1.9.1
SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.3.0.0 = Gauge32: 11
SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.3.0.1 = Gauge32: 22
SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.4.0.0 = Counter32: 21
SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.4.0.1 = Counter32: 23

To my understanding is that after the 9.1.3. the next entry is the slot and
the last entry is the port.  The interfaces in the 2821 are numbered as
T0/0/0 etc.....The cards are VWIC2-2MFT-T1/E1.  

I want to monitor DS0's in each DS1 but I am unable to successfully.  If
someone can please assist me in letting me know what I am doing wrong I
would greatly appreciate it.  

Cisco 2821 IOS version: c2800nm-spservicesk9-mz.124-15.T3.bin
MRTG version: mrtg-2.12.2
