After a shutdown/no shutdown command on interface, transceiver doesn't come back. Tx signal gets stuck at -40 and current values read as 0.

Only solution is to disconect transceiver physycly from device and connect back.

@Popeye_Wang I'm checking with the qsfp vendor. Strangely , the sfp works fine, just doesn't come back after a shutdown.
