We have been having network issues lately, and the only issues i see on our 4510R switch is with port flapping on a few ports.... my question to you is, would
port flapping on a few ports cause the network slowness for everyone? for example data transfer speeds going from 10 Mb per sec to 1 Mb per sec?......
Also, is it best practice to leave the autonegotiate enabled on Gb connections.... and not to force them to gigabit?..... ..
