Hi Mark,What I mean is, amber light no equal to error. Let's say your upstream device is a 10/100 switch, but your 3750's port is Giga port. auto / auto configuration will learn the speed / duplex as 100 / full & the light of that port become amber.I...
Hi Mark,If the port status is up/up, the port should be working. Amber light may indecate the port not running at it's best speed / duplex mode only. Also, you should check on the error counter on that interface & logs.
