Hi,
I have a brand new C9800-L-F-K9. I ahve this planned to connect to a switch C9300. On the datasheet, i see 2x 10G/Multigigabit fiber ports and also 4 X Quad RJ-45 2.5G/1G Multigigabit Ethernet ports.
My question is, on the switch port connecting to the WLC can be just a copper port here or only SFP port is supported?
And also what is the use of the 2x 10G/Multigigabit fiber ports and 4 X Quad RJ-45 2.5G/1G Multigigabit Ethernet ports.

mGIG is a copper port so the switch needs to support mGIG as well.

NO. As per datasheet, it says 2x 10G/Multigigabit fiber ... So, It is a fiber port only as per my understanding.
My question is what's is the use of the 4 X Quad RJ-45 2.5G/1G Multigigabit Ethernet ports. And can i use these ports to connect to the switch C9300 with a copper connectivity.

Thanks.
So i can use any of the 4 X Quad RJ-45 2.5G/1G Multigigabit Ethernet ports from the WLC connecting to the cisco 9300 switch with a copper connection say port gi1/0/12 on the switch.

Can be done but the speed negotiated will be 1 Gbps only since the switch can only support 1 Gbps.

I donot have a lab device to test. The devices were procured by customer. And we both need to finalize the design and i have to configure that. Customer have not procured any SFP for the WLC connectivity. So, I wanted to confirm on a solution by providing copper connection to the switch.
