Depends on a few things. I've seen some devices (Cisco 3700?) with that report the speed of auto-negotiate ports with nothing connected as 10 MB. Then when you connect a 100 MB or 1 GB device to the port, the router starts reporting the port speed as 100 MB or 1 GB. So that could be what you're seeing.
thanks for the reply.
yes, i believe you may be right. that sure seems logical it would be doing that. and it may actually be a good thing to detect something like a server which has 'auto nego' settings on.
because we try to turn off 'auto nego' and fix the speed...fewer issues with the switch ports with doing that setting.
