Orion shows 3750 port speed changes - is it normal?
We use Orion for monitoring. We recently started monitoring a workstation switch and find many occurances of port speed changes indicated. Our workstation ports are configured with auto speed and duplex. Is it normal that we are detecting speed changes on the ports? Do workstations running XP automatically adjust their speed for traffic management or power save? Perhaps something like speeds changing when PC goes to sleep mode but has wake on LAN enabled? Is it possible that the MIB is misreporting?
I realize that there are many different NIC vendors/drivers that might act differently. Just wondering (in others experience) if it is somewhat normal or if there is anything on network I should be looking into as to why speeds are changing? We plan to not monitor workstation ports (only uplinks) on the switch.. but before we do, I thought I would see if what we are detecting needs to be addressed?
Here is an example from Orion of a speed changing. Seems always off hours:
