Thanks for your help, Adam. I know about Dell’s snmp shortcomings. At one point I found a bug in one of their switches that had to do with them using a signed int instead of unsigned int for their counters. Really threw MRTG for a loop.
Anyway, I knew MRTG used to work with these switches, but I was dumb and decided to upgrade them to the “latest” firmware (6.1.2). That’s what broke it. I’ve downgraded back to 6.0.4, and the switches are returning ifDescr values again.

This device isn't returning an ifDescr or an ifName for its ports, which is invalid.
Typical Dell. There isn't really a workaround for this.

All of the ports seem to be being ignored :
Ports : XXXXXXXXXXXXXXXXXXXXXXXXXX
Run the ports poller in debug :
./poller.php -h 29 -m ports -d

Hello. I'm having trouble getting Observium (CE 0.14.4.5229) to recognize ports on my Dell PowerConnect 3048 and 3024 switches.
It appears these switches only support SNMP v1. Observium connects and grabs SNMP contact, location, etc. but doesn't see ports. Here's output from add and discovery for my 3024 switch:
# ./add_device.php switch-ne Observium v0.14.4.5229 Add Device(s)
Try to add switch-ne: Trying v2c community public ... No reply on community public using v2c. Could not reach switch-ne with given SNMP community using v2c. Trying v1 community public ...

I can do a snmpwalk on these switches from the same machine that Observium is running on and can see all the interface information. Is there something I need to tweak in Observium to get these switches discovered correctly?
Thanks!
