I have a question regarding the giga port o catalyst 4500 switches.
I read that for giga links, auto-negociation is the best (speed, duplex, pause frame). Then what happens if the speed is forced, with a cat2960 switch, even with not crossed cable and using the mdix-auto fonction ? (the link is ok)
speed 1000, duplex full on both side (cat4500, cat2960)
I found the the mdix-auto fonction run with auto-negociation. Then the speed is forced (the duplex too) with the mdix-auto and a not-cross cable. The link seems to be ok anyway.
So is the fixed configuration really used ?
the card on the cat4510 is a WS-X4448-GB-RJ45; On the remote side we have a cat2960 using the giga port (gi 0/1).
I would think that the only reason you would want auto on any link is if you think there will be a slower speed connected. On gb links, chances are a host is connecting at 100mb, and if you set to 1000/full, the host won't connect because the port won't negotiate a slower speed. If you have two gb ports connected and hard coded and the link is up, you're fine.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
