Difference between SFP GLC-LH-SM 30-1299-01 and GLC-LH-SM 30-1299-02?

Is there a place where i can find the difference between SFP GLC-LH-SM 30-1299-01 and GLC-LH-SM 30-1299-02?

Also i am looking for information if there are any issues using SFP GLC-LH-SM 30-1299-01 with any specific IOS on 2960?

Thanks,

Satish

Those are internal part number.  They are all the same and the difference is most likely be the TRUE manufacturer.  You can identify who is the real manufacturer by doing some diagnostics or just by looking at the first three character of the serial number of the SFP modules.

Regarding the second part of your question, Cisco publishes a compatibility matrix here listing which transceivers are comaptible with which devices and the necessary IOS level.

Thank you for clarification. Looking at SN numbers these seems to be Cisco ones. SFP SN numbers of the not working (

GLC-LH-SM, 30-1299-02 ) ones are starting with FNS13460xxx. IOS on 2960 switch is 2.2(53)SE2.

If you're finding Cisco parts that are listed as compatible to not work in your switch, I'd suggest opening a TAC case to have them resolve the issue.

FNS means the SFP was made by Finnisar and manufactured between 08 to 12 November 2010.
