DWDM-SFP10G miss inventory in 3750X switch

[wenzhkcom]

Hi, 

I noticed that show inventory not showing DWDM-SFP10G-xx.xx transceivers with ITU channel of 20/25/30/35 in WS-C3750X-24T-L. Anyone also notices this issue and knows the reason?

Hi

Are you definitely using a Cisco transceiver that's supported ? some 3rd partys may work but may not register in inventory

is it still working away , you could try re-seat it if its definitely a supported sfp

are you on a higher image than 15.2 looks to be supported after that IOS version n the matrix
