Hello everyone,
we see on one of our QFX fabric missing VCP links from fpc1 to some spine switches.
The links seem to be up and are auto configured as VCP.
However, there is no neighbor displayed with show virtual-chassis vc-port:

While port 0/6 is even displayed to be down, it is up on the remote side (it is
the link to fpc8):

Does anybody have an idea why the fabric would not see the neighbor? I doubt
this is related to the cabeling because there were no changes made and we
verified that the cables are in place.
This is MPC connector, therefore it is strange that the connection between
fpc1 and fpc8 is displayed down on fpc1 in cli while it is up on fpc8.
