I find it useful to standardize on 10/100 Ethernet ports with RJ-45 jacks for Ethernet and Fast Ethernet connectivity. Then use media converters, either standalone or rack-mount, to put these speeds onto MMF (up to 2km) or SMF (up to 80km). Avoid switches with built-in 100FX ports, or chassis modules with all-100FX ports, unless they make sense in your design.
Also, standardize on GBICs for Gigabit Ethernet connectivity, if you can. Lets you customize how many TX, SX, LX/LH, and ZX ports you have. Don't go with all-1000BASE-SX or 1000BASE-T modules, or fixed ports of same, unless they make sense in your design.
10/100/1000 ports with RJ-45 jacks are kind of neat; too bad they don't come in a single 48-port switch or chassis module yet.
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...
