SNMP Query for Ethernet Duplex Settings

Steve Bonds — Mon, 15 Oct 2001 16:06:50 GMT

We have a bunch of systems that seem to like to come up in half-duplex mode even though the switches are set to full duplex. I'm looking to find an easy way to check all the systems on a network periodically to make sure that they are set properly.

Does the HP-UX SNMP agent provide any way to check the ethernet duplex settings? I didn't see anything on this in the HP-UNIX MIB. Is it hidden away in another MIB?

Hi Steve:

Nail the full duplex setting in the appropriate network configuration files:

You can verify the settings with:

# lanadmin -x

Have you gone into sam and set them specifically to full-duplex? After doing that, they should not come back up any other way.

Hope this helps
Chris

Thanks for the quick replies on how to set the duplex!

However, I'm still looking for a way to *check* the settings via SNMP to confirm that everything is good. This will help me identify systems that have the wrong settings for whatever reason. (Fresh install, new NIC added, lost in a corner and recently powered on, sysadmin error, etc. etc.)

I found the spot-- the duplex settings appear in the text of the MIB-2 ifDescr field (mib-2.interfaces.ifTable.ifEntry.ifDescr).
