Generally speaking, the first box switch number of 1 and Huasan is 1, so 9 ports are generally 1/9, and 14 ports are generally114. As for G or E, it's up to you to switch.

2.g stands for Gigabit port and E stands for 100M port. As for FE, it is the same as E, and GE is the same as G;

3. G2/0/ 14 respectively stands for: 2 stands for slot 2, and 0 generally has no practical significance; 14 stands for port 14. The default slots of Huasan's box switches are all named after 1, so you can't see the ports starting with 2 unless you are virtual. Huawei's ports generally start with 0, so Huawei's ports are generally 0/0/ 1 and so on. As for 14, I said port 14, not port 14, because some switches start from 0, so 14 is the fifteenth port. But the box switch rarely starts from 0, and usually appears on the box switch.

Ordinary box switch, the ports you see on the default panel are all in a slot, and those ports you see are all in a slot. Of course, if it is a switch that can expand the board card, the slot is generally on the back of the switch, and that model usually has C, such as Huawei's 5720-36C-EI-AC. C in 36C indicates that it can be expanded, but most box switches can only expand four ports. In other words, it mainly depends on the model. There is only one slot without C (except box switch), and there are two or more slots with C. There are also special models, such as H3C's 5800 series, and some models can expand several slots.
