MIB for PC-Engines Alix

[swiri]

Hi all,

I am new to SNMP and this might be a silly question so apologies in advance. I spent most of the day Googling but couldn't find an answer.

I have an Alix from PC Engines and I have SNMP installed. I want to query the interface status so I understand the device needs to support RFC 1213 (IF-MIB)

If I run on the device itself: snmpwalk -v1 -c public localhost

I get the contents of the devices MIB which is very basic and doesnt seem to contain anything related to interface status:

I can't seem to find a new MIB from the manufacturer. Is there anything I can do to query the interface status via snmp on this device?

Thanks

Looks like that is all it supports.

There is a chance that they have limited the -v1 public view, to only see part of the supported MIB objects.

You would need look at their documentation for more info.

Thanks Bill. It looks like you are right. The default snmpd.conf file was limiting what I could see when using snmpwalk via public view.

rocommunity public  default    -V systemonly

This was the culprit right here. Once adjusted it works fine and gives me all the info I need.

Thanks again
Swiri

Interesting. Little surprised they would do that by default, but there it is.

Glad to see things are working for you.
