Cisco catalyst 9200 Module Issue

[tonyplueard]

We have Catalyst C9200L-24P-4X. I was swapping out an older switch for one of these. When I plugged a 1000base-SX SFP module in the system is reading it as a 10G LR module. We are running version 17.03.03. When doing a show inventory it does show the proper SN of the module.

Is the SFP a non-Cisco branded variety?

[tonyplueard]

No, it is a Cisco Systems 30-1301-01 GLC-SX-MM

[Mark Elsen]

          - Check SFP compatibility with : https://tmgmatrix.cisco.com/?npid=1767

[tonyplueard]

According to what was found on the Matrix the GLC-SX-MM is supported.

[DanielP211]

If you have a third party vendor SFP you can use the following hidden commands:

no errdisable detect cause gbic-invalid
service unsupported-transceiver 

[tonyplueard]

This is a Cisco Systems branded module.

[Leo Laohoo]

Please post the complete output to the following command:  sh idprom interface <SFP PORT>

Make sure the optic is in the port when entering the command (above).

Optics is made by Finisar and it is showing to be a GLC-SX-MM but the switch is saying it is a SFP-10G-LR.  

This is a bug with the firmware.  I recommend upgrading to 17.9.3.

[tonyplueard]

I will do that and let you know the results.

[tonyplueard]

Upgraded to 17.9.3 still have the same result.

[Leo Laohoo]

Interesting results. 

Do not bother raising a TAC Case.  IF the TAC agent sees the optic is an end-of-support GLC-SX-MM the case would only be closed or terminated.  

Try talking to your Cisco AM/SE but I doubt any good it will do.

 - Have a test with this (advisory) release : https://software.cisco.com/download/home/286320046/type/282046477/release/Bengaluru-17.6.5

As soon as the cisco site allows me to actually download it, I will be testing that version.
