[j-nsp] FPC shell command to disable the interface Tx laser

[Olson, Martin]

I got the answer offline.  On an MX or T-Series router for a 10GE
interface, use the following commands:

 

start shell pfe network fpcX

test xfp <index> laser off

 

You can find the XFP index by doing "show xfp list" from the shell
prompt.  I haven't seen a method that works for SFP interfaces.

 

For sonet interfaces, this hidden configuration is also an option:

 

set interfaces so-0/0/0 sonet-options insert-los

 

Thanks,

I have a lab environment and I want to simulate a fiber cut, but I'm not
able to physically pull the fibers.  I know that if the CLI is used to
disable an interface, the code has mechanisms that assist protocol
convergence.  I saw a JTAC engineer enter a command from the FPC shell
that cuts the power to the laser of an interface, but I didn't write it
down.  Does anyone know how to abruptly shut down an interface like
that?

 

Thanks,
