Hello All,
My telecom operator give us for Internet access by fiber some Sercomm GPON SFP model.
Professionally, when used on 2960X (or 2960XR), no problem to use "service unsupported-transceiver" command and get the GPON SFP working.
Personally, at home, I'm using a 2960L (less budget ;), but with the same release version "15.2.5E2", this command doesn't work.
Is there something to do to get this work ? (I've try version 15.2.5, 15.2.6, 15.2.7 with no success :( )
Thanks in advance,
Grégory

have you pasted that command in config t mode :
service unsupported-transceiver <<-- do you see any errors - hidden command and it takes it try and let us know.
or other option below :
no errdisable detect cause gbic-invalid

@Leo Laohoo good catch on the version.....
So on the orginal post you mentioned you tried all the versions (all are same ) - is this possible to upgrade to high level code feature to test ?

I've get an ISR G2 Temp Data from Licence Portal for my switch.
Is this switch could be upgraded to Lan Base ?
There is no "license install" command :/
Or maybe I misunderstood your request
BR,

2960 licenses are fixed and cannot be changed.
Check e-bay for used GLC-SX-MM. They're not that expensive any more.

Is there a workaround? Is the command no errdisable detect cause gbic-invalid enough?
Thank you.

The Cisco-branded GLC-SX-MM (not GLC-SX-MMD) are cheap in the gray market (like e-bay).
Don't take the risk of getting non-Cisco branded ones.

yes if the SFP not cisco one. again this is in generic command, if that is not working, you need to provide more information.
