Connectivity problem with Cisco 4948
Hi Cacti experts,
I'm new to Cacti and the forum. Please excuse if the issue has been discussed before, but I wasn't able to find any answers so far.
I'd like to use Cacti to monitor a number of Cisco 4948 Switch interfaces. The Cacti installation has been up and running for a while and is being used successfully to monitor several other network components.
Now I've added the Cisco Switches and keep encountering the same problem: Some of them are identified as "down" or at least intermittently have no SNMP connection. After adding a device, the SNMP info is displayed correctly and the TCP ping is successful. When I list the associated data queries, I also get a correct result, which allows me to create the graphs for the interfaces I need. So far, so good.
However, when listing the devices, some of them are consistently reported as "down" and their graphs are not created. When I click on a device to check the details, the SNMP info and ping results are fine. Some of the switches I added work just fine - they are "up" and graphs are drawn. I can see no pattern as to which devices work and which don't. They have identical configurations (as far as SNMP is concerned) and the same IOS version. When deleting a group of devices and adding them again, other switches than before might be "up" or "down". When I change downed device detection to "Ping or SNMP", the device is detected as "up" and a graph created. However, it only contains "NaN" values.
I worked my way through gandalf's debugging tutorial (http://docs.cacti.net/manual:087:4_help.2_debugging). This is what I found:
- Hosts are detected as "down" (or get SNMP timeouts if I change down detection setting)
- Scripts / Permissions are OK, they work for some devices
- RRD files are either not created or contain "NaN"s, depending on down detection setting
- Minimum & Maximum settings are OK, results should be within bounds
- No problems found in the rrdtool graph statement
- When using snmpwalk from my Cacti-Server, I can reliably retrieve all values from all devices
- Tried setting Maximum SNMP OID's Per SNMP Get Request to 1 -> no difference
My system:
Cacti Version: 0.8.7e
Cacti OS: unix
SNMP Version: NET-SNMP version: 5.3.0.1
RRDTool Version: RRDTool 1.2.x
Poller: spine
I would really appreciate any pointers as to where I should be looking for the problem. Thank you very much!
Cheers,
Matt

Sorry this took a while - some other projects came up and I had to get root access for the Cacti-Server.
Anyways, here's what tcpdump is telling me.
This is a poll cycle for a switch that is working:
And a cycle for one of those that isn't working:
Switch_2 does seem to be answering all requests, but maybe not correctly. Any ideas what to look for now?
Thank you very much for your help.

Switch_2 does seem to be answering all requests, but maybe not correctly. Any ideas what to look for now?
Thank you very much for your help.
Now you mentioned it, I decided to try setting up SNMP v2. Graphing seems to work without a problem with SNMP v2. Now I feel kind of stupid for not testing this before.
So the problem is definitely with SNMP v3. Do you have any further info on the "rumors" around v3 problems?
I'm trying to use v3 with AuthPriv, MD5 and DES.

What spine poller are you using. Can you please test the latest SVN and see if that helps with the random connectivity problems.

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?

Hi experts,
I have the same problem, as matt85 described. But in contrast to him, I HAVE to use SNMPv3. Could you please inform me about the rootcause of this situation and how I can fix it?
tcpdump output:
IP x.x.x.x.port > y.y.y.y.snmp F=apr U=snmp [|snmp][|snmp]
IP y.y.y.y.snmp > x.x.x.x.port F= U=sn [|snmp][|snmp]
I use the following command:
snmpget -v 3 -l authPriv -u someuser -c somecommunity -a SHA -A somepass1 -x DES -X somepass2 -e someEngineId y.y.y.y:161 system.sysUpTime.0
Regards, artmik

I am using spine 0.8.7e.
I only just discovered the patches at http://cacti.net/spine_download_patches.php
Since I don't have a backup of the Cacti server (and can't easily pull one), I'd like to try the patches before the latest SVN. However, I've run into some trouble updating autoconf. I'll have to resolve that first and then try the patches. I'll keep you posted.
