Mixed use of GLC-SX-MMD and SFP-10G-SR in C9800-L-F

[Rps-Cheers]

HI all

PID: C9800-L-F-K9

NAME: "subslot 0/1 transceiver 0" is PID: SFP-10G-SR 

NAME: "subslot 0/1 transceiver 1" is PID: GLC-SX-MMD 

Such an interface is 10G, and the other is 1G. Will there be any problems with simultaneous mixed work? If you need to make them all work, do you need any commands?

Thx

Q.  What are the SFP/SFP+ optics supported with the Cisco Catalyst 9800 Series Wireless Controller appliances?

A.    

Supported SFP/SPF+ optics
SFP-10G-SR SFP-10G-LR SFP-10G-ER GLC-EX-SMD GLC-SX-MMD GLC-LH-SMD GLC-ZXSMD GLC-TE SFP-10G-SR-X SFP-10G-LR-X DWDM-SFP10G-30.33= SFP-10G-AOC2M SFP-H10GB-ACU7M

Q.  How do I switch from 1G to 10G or 10G to 1G uplinks?

A.  No special operation - replacement of SFP or SFP+ enabled 1G or 10G links.

Yes, I found this. But if two interfaces are plugged into 10G and 1G modules at the same time, will it cause one of them to work abnormally?

[Arshad Safrulla]

For sure you cannot bundle the ports, but if you are using it as individual ports it must work.

In this setup are you facing any issues?

[Rps-Cheers]

YES，We insert the module as follows.

NAME: "subslot 0/1 transceiver 0" is PID: SFP-10G-SR 

NAME: "subslot 0/1 transceiver 1" is PID: GLC-SX-MMD 

But the 1G module cannot be up. We have done a cross test, and the interface can be up and working when the module is changed to another device. We also changed the line, but it is useless.

        - Can you see anything in the logs when these tests are done ?

I am sorry for late reply. i can only see the log of module insertion and remove, there is no more log.
