We have a problem with the XENPAK-10G-LR that doesn't switch off the lasser in shutdown state, installed in 6509 with WS-X6704-10GE. The other side of the connection doesn't detects the shut.
I have checked that the X2-10G-LR disables the light, then the other side see the interface as down/down.
What is the cause?
Any method for disable the laser?
