Canopy SM and Monitoring with SNMP

We are trying to use Cacti to graph RSSI and Jitter on a Canopy SM. What’s strange is that if I do an snmpwalk from my server, I get values for .1.3.6.1.4.1.161.19.3.2.2.2 I get a result just fine, but if I try the same thing with snmpget, then I get this error: “WHISP-SM-MIB::rssi = No Such Instance currently exists at this OID”. What the heck is going on here? Has anybody got a graphing working with Cacti/MRTG?

Here’s some output:

# snmpwalk -v 2c -c ctisnmpread 63.250.228.93 .1.3.6.1.4.1.161.19.3.2.2.2
WHISP-SM-MIB::rssi.0 = INTEGER: 927

# snmpget -v 2c -c ctisnmpread 63.250.228.93 .1.3.6.1.4.1.161.19.3.2.2.2
WHISP-SM-MIB::rssi = No Such Instance currently exists at this OID

Wulfhere,
The SNMPGET operation is used to retrieve a specific OBJECT (leaf object). In this case, since RSSI and Jitter are scalar variables, you will need to add the instance in the end. So you use .1.3.6.1.4.1.161.19.3.2.2.2.0 instead.

Let us know if this helps.

That did it. Thank you very much?
