everyone! I want to buy a Huawei switch with GE ports, does Huawei S6720 model have GE port?
There's something like 22 models of Huawei S6720, so it would be better to check with the specific model, but this answer should apply to all.
According to this page from Huawei documentation
10GE SFP+ port A 10GE SFP+ Ethernet optical port supports auto-sensing to 1000 Mbit/s. It sends and receives service data at 1000 Mbit/s or 10 Gbit/s.
So while those switches have only 40/10G interfaces (except for the management interface) those interfaces can operate at gigabit speed.
Huawei S6720 model doesn't have GE port, it is 10G SFP+ switch (also have 40G ports), but ports on S6720 are auto-sensing from GE to 10GE; if you put GE module, then it will be GE ports.
