Your output shows nothing plugged into 2/2/0. If you do it's not registering.

Not needed to insert any XFP for interface status.

Have you tried downgrading the Junos to the last supported relaease and verified the behaviour?

why? and can't downgrade/reboot card, because mx960 in production Smiley Sad

if port 2/3/0 at the same fpc works fine.

also another dpce-4x XFP also works fine.

 

i think problem come into sight after creating and removing lt device at port 2/2/0

Hi Vlelin,

A restart or reseat of the FPC will solve the problem.

You may see other ports working or not working randomly but with DPCE and JUNOS 17.4

You are on Your own in this regard - as I mentioned earlier, DPCE are not supported in JUNOS 17.4, period.

As for what happens if You insist on using a non-supported release - see RFC 1925 section 2(3) https://tools.ietf.org/html/rfc1925
