[c-nsp] Cisco WS2960-X - Are these switches lemons or is there a stable release?

Indeed, not only do they stop forwarding on the copper SFPs, the SFP tends
to drop off entirely (just generates that lovely HULC error when you query
the ethernet-controller phy detail).

And, for extra fun, some iterations of the hardware will also (when the SFP
fails) start generating:

"%ILET-1-AUTHENTICATION_FAIL: This Switch may not have been manufactured by
Cisco or with Cisco's authorization..."

Which causes the switch to stop forwarding all traffic. Requires a full
power cycle to restore.
