I have C9300-24T with C9300-NM-4G

I inserted 1 GLC-LH-SM  on the C9300-NM-4G but it doesnt work

I configured it as trunk

interface GigabitEthernet1/1/1
switchport mode trunk


I have err_disable

Is it normal ?

Please SFP module GLC-LH-SM  can work with C9300-24T (C9300-NM-4G)


Please advise

Hi nicanor00,


Can you confirm if the SFP model is GLC-LH-SM or GLC-LH-SMD?


Also provide the version which is running and the complete error which you are getting.

GLC-LH-SM is not supported for the C9300-NM-4G


SMD is supported. However if it is SM then it is not supported as the compatibility Matrix


Please find the attached snapshot for the same. You can use any supported SFP's.


Hope this helps.
