Try this as it gives a matched pair
 
Target[tower001.ap101]: 1.3.6.1.4.1.161.19.3.1.7.1.0&
1.3.6.1.4.1.161.19.3.1.7.1.0:Canopy at 10.254.1.101:::::2

Hello everyone, 

Hopefully I have a simple problem.  I am trying to pull the number of
clients from a Motorola Cyclone Access Point.  I have figured out the
OID number to use, it is: 1.3.6.1.4.1.161.19.3.1.7.1.0.  

I can snmpwalk from the machine that mrtg is running on and get the
expected response.  Here it is:
snmpwalk -v 2c -c Canopy 10.254.1.101 1.3.6.1.4.1.161.19.3.1.7.1.0
SNMPv2-SMI:: enterprises.161.19.3.1.7.1.0 = INTEGER: 28

Here is my cfg file for this:
#
# File: /etc/mrtg/registered_SM_count.cfg
#
# Configuration file for gathering number of registered SM's on AP's
statistics 
#

#
# Define global options
#

WorkDir: /var/www/mrtg/
# Refresh brower window very 5 minutes
Refresh: 300
LoadMIBs: /usr/share/snmp/mibs/SNMPv2-MIB.txt,
/usr/share/snmp/mibs/SNMPv2-SMI.txt 

#
# Registered SM Monitoring
#

Target[tower001.ap101]:
1.3.6.1.4.1.161.19.3.1.7.1.0:Canopy at 10.254.1.101:::::2
Title[tower001.ap101]: SM Count Tower 001 AP 101
MaxBytes[tower001.ap101]: 200
PageTop[ tower001.ap101]: <H1>SM Count for Tower 001 Access Point
10.254.1.101</H1>


The error I get is:
2007-02-09 12:20:38: ERROR: Target[tower001.ap101][_IN_]
'1.3.6.1.4.1.161.19.3.1.7.1 . $target->[0]{$mode} ' (warn): Use of
uninitialized value in concatenation (.) or string at (eval 15) line 1.
2007-02-09 12:20:38: ERROR: Target[tower001.ap101][_OUT_]
'1.3.6.1.4.1.161.19.3.1.7.1. $target->[0]{$mode} ' (warn): Use of
uninitialized value in concatenation (.) or string at (eval 16) line 1. 


I notice that the OID number is one digit short, it is missing the last
0.

I am thinking that I may need to use WaLK prepended to the OID.  Just
not sure how to do that.  I cannot find a decent example of its use. 

Any ideas?

Thanks,
