[c-nsp] Port-channel not working Juniper vs Cisco

Hi
I've deactivated the FAST on Juniper but nothing changes...

As I wrote on Cisco remains down hence you will not see any LACP while on
Juniper it flaps, once I shut on cisco it stop to flap
I'm not sure it is a cabling issue...
we should try to setup a pure L3 p2p link and test that I guess...

See the output:
