Configure 3750 Duplex and Speed via SNMP

[DrittesBinom]

Hello,

i need to set the Port Speed and Duplex via SNMP on a Cisco 3750 - the problem is that i cannot find out which OIDs i have to use here.

I already made a snmpwalk and checked the file for any entries that would lead to "Duplex" and "Speed", but couldnt find any... (i.e. i found the "ifSpeed", but you cannot write into this)

So I'm quite stuck now. How can i find out how to change Duplex/Speed over SNMP?

Thanks in advance!

Ah ok, i thought this was just a "restriction" from the CLI...

jclarke, unfornunately i got a new problem (and as it seems i still didnt recognize the schematic behind the "find OIDs for properties"-problem).

Now i got a 65xx Switch, and need to do set the same Properties(Speed, Duplex, VLAN) like before on the 3750. And what I've found are the supported MIBs for this switch on the Cisco website. As supposed, the OIDs i had before (portAdminSpeed, portDuplex, vmVlan..) do not exists in these MIBs. How do I find the equivalent OIDs for this switch now? :(

Imho the online documentation isnt sufficient enough, or i cant find anything useful.

Seems as if the OIDs/MIBs are supported, even though they are not listed under "supported MIBs" on this website...*grml*

Sorry for the confusion
