Firstly, yes I know this is a really fundamental question but his forum is the fastest and most trusworthy source of cisco knowledge Ive found to date!
What exactly do the following colours on the port LED's mean:
Thanks in advance.Matt
Lemme try and depending on the model of your switch ...
no light - no remote connection or port in shutdown (except for 6500)
solid orange - port in error disable, spanning-tree negotiation, Trunk to access port mismatch or switch may have a faulty port. Port is shutdown for a 6500.
flashing orange - Depending on your switch, 2900/3500 means duplex mismatch error.
flashing green - port working fine.
Hope this helps. Please rate when applicable.
