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.
