At the University of Fulda I had a similar case: Our Cisco AGS router
said that line speed is set to T1 (1.544 Mbps), but it was actually 2xS0
(128 Kbps). But this is just the nominal bandwith.

The DESCRIPTION for the ifSpeed object descriptor (MIB-II) says:

An estimate of the interface's current bandwidth
in bits per second. For interfaces which do not
vary in bandwidth or for those where no accurate
estimation can be made, this object should contain
the nominal bandwidth.

So maybe your interface vary in bandwidth.

Best regards

Jan.
