Cisco Switch Naming Convention

痴心VS绝对

　　From : https://supportforums.cisco.com/discussion/10697231/cisco-model-naming-convention
　　Does anyone know where to find a posting of what the parts of a cisco model name mean?
　　ex. WS-C3560G-24TS
　　==================================================================
　　I've never seen an official doc on it, but as a partner, I occasionally see a quote that has something regarding it. For your example,
　　WS=Workgroup Switch
　　C=Cisco
　　3560=Hardware Platform
　　G=Gigabit
　　24=Number of ports (not always accurate because it doesn't always count uplink ports. It's usually the number of ports for access.)
　　T=Ethernet I think, however there is also P which is for PoE.
　　S=Standard Image
　　These can sometimes vary so don't take this as gospel, but it should be pretty close.
　　Hope it helps.
　　=============================================================
　　Ex: WS-C2960X-48FPS-L     (这个示例更加准确）
　　WS = Switch
　　C = Catalyst
　　2960= Model
　　X = Series ( X *OR* XR )
　　48 = How many Ethernet 10/100/1000 ports (24 or 48 )

　　FP =>
　　S = number of SFPs  ( it is used to>　　-L = IOS Feature set ( for X series :  -L = LAN BASE *OR* -LL = LAN lite ) , ( For XR : -IL = IP lite)
　　NOTE: We have 2 Exceptions for this concept:
　　=============================================================
　　1- WS-C2960X-24PSQ-L : Watt not mentioned,S=4SFP , Q is a new symbol.
　　This Switch have only 2 SFP and 2 1000BASE-T , Its is also have POE on just 8 ports with 92w.

　　2- WS-C2960X-48TS-LL :>　　=============================================================
