I check and got advise with a Cisco partner, they had suggested to use SFP-10G-SR for my C2960XR-48FPS.
Had encountered the switch is not detecting the SFP module.
The model is always "Unknown".
Want to know if the SFP is compatible wit hmy switch though the partner may have made a mistake.
check the compatable matrix :
and good matrix and explanation :
Thank you all.
Learned about the incompatibility given my newbie for SFP module.
Going need source a new switch to support this SFP module.
yes, that is the reason while doing BoM need to cross check before we buy
if found the solution mark as solved.
C2960XR-48FPS-L support 1G SFP only you can use GLC-SX-MMD for multimode and GLC-LH-SMD for singlemode,
If you wish to use SFP-10G-SR you need to change the switch to C2960XR-48FPD-L
hope this was helpful
