ㄟ.....最近被問到兩次有沒有推薦的 L2/L3 switch, 後來我發現我還滿愛推薦 cisco 的, 我分別推薦了 2960, 3560 跟 3750.....(我的工作跟 cisco 無關阿~~~)然後又被問到具體要買的型號~ 順便來整理一下吧.....:)

2960/2960S

首先是 2960(2960S), 有兩種 IOS 可以選: Lan lite 跟 Lan base, 在選的時候就要選好了, Lan lite 是無法升級至 Lan base 的, 差別的話最簡單的就是 Lan base 可以用 SVI (Switch Virtual Interface) 實現 L3 的功能. (印象最多好像是 16 筆)
以下表列 Lan lite 跟 Lan base 不同的地方及型號列表.

3560-X, 3750-X

3560 有兩種 IOS 可以選: Lan base 跟 IP base, 而 3750 有三種可以選: Lan base, IP base, IP services.
