Can you do a simple snmpwalk to the device to double-check that SNMP is
running and configured correctly? I've run into that.

I can understand that.
I got th econfig via cfgmaker, when I run cfgmaker, I get a config for each
port on the switch. Not only this, but all ports that don't exist.
How the PowerConnect switches work is that you can stack up to I think 5.
When they are stacked and you try snmp, it will respond back with all
*possible* ports. So if you only have two, you will have ports for all 5 in
the config, which means you will have a lot of cleaning up. The port I used
for an example is an active port so I should see no reason for it to work.
The cfgmaker line I used is similar to that of what I used on the other
switch that is working as well as all other devices.
**
/usr/bin/cfgmaker --ifref=descr --global 'WorkDir: /home/mrtg/html'
--global 'Options[_]: bits,growright' --output /home/mrtg/cfg/mrtg.test.cfg
foo at 172.20.100.200
**
Doing this gives me all ports and all are remarked out, so I have to go
through the list and unremark the ones that are actually live. Some of
these ports are assigned to other VLANS, but the system I am running the
cfgmaker has access to all VLANS, this wouldn't possibly be the problem
would it? That is the only other thing that I can think of. I can reach
anything plugged into each of these ports so I should be able to get data
from these ports, or is my theory all wet?

When using the interface number, that is given by default when running
cfgmaker, the syntax 2:foo at 172.20.100.200: is correct IF there is an
interface 2 AND it is active on the device. That is not always the case.
For
instance I have a switch with slots for GIG uplinks, that are my interfaces
1 & 2, so to monitor the ETHERNET ports, I have to watch 3-26, not 1-24.
Did you get the cfg file by running cfgmaker or did you create it by hand?
If you did it by hand, try running cfgmaker foo at 172.20.100.200 and see if
that gives you the interfaces you are looking for.

Now I am confused. If that is the case, why does the other switch work with
this config?
Target[172.20.100.200_2]: 2:foo at 172.20.100.200:

The bit you are talking about in front of the comm string increments with
the ports on the switch, so that also confuses me, so port 1 it would be
1:foo, 2:foo, 3:foo, etc....

MRTG needs 2 OIDs in the target line. You have this
Target[172.20.100.202_1]: 1:foo at 172.20.100.202:
You need something like this
Target[172.20.100.202_1]: 1&1:foo at 172.20.100.202:
I'm not 100% sure of the syntax since I always explicitly list whatever OIDs
I am trying to get. I would do it like this:
Target[172.20.100.202_1]:
ifInOctets.1&ifOutOctets.1:foo at 172.20.100.202:::::
Not sure of the mrtg shorthand.
But for sure one of your issues is that you need to collect two metrics.

I am trying to setup another Dell switch for SNMP polling. I have one switch
working but am running into problems with another similar switch.
I ran debug and I see it running through the config lines:

But I don't see any snpo lines, such as the ones below:
--snpo: simple If: .100
--snpo: simple If: .100
--snpo: SNMPGet from foo at 172.20.100.200: --
ifInOctets.100,ifOutOctets.100,sysUptime,sysName
--snpo: SNMPfound -- 'undef', 'undef', '32 days, 21:17:52', 'undef'
I am trying to get this to work via Big Brother and I wonder if this is my
overall problem.
