IOS SNMP port speed (ifHighSpeed)

[trush]

Hi, Does anyone know how to return the SNMP ifSpeed/ifHighSpeed on a e10/100/1000 port (portType=61). I find that ifHighSpeed returns 1GB no matter what the port speed is set to.

MIB portAdminSpeed does return the correct speed however this doesn't help when the port is autoconfigured as the value of 1 is returned and not the port speed.

IOS: 12.2(17d)SX

Device: WS-C6509

Any Ideas.

For switches running IOS, the ifSpeed didn't return the right value on all the Gigabit ports of a Cat6000 with SUP720. The operation speed is higher then what is configured on the switch.

OK, sort of stumbled on a win situation (I hope). I found if you use OID portAdminSpeed to return the speed it worked on non autoconfigured ports. If it is autoconfigured it returns one(1). If I get a return value of one(1) I then check OID ifHighSpeed and it seems to give the correct autoconfigured speed. Fingers crossed. Sorry, I didn't mention it is a SUP720.
