Próbuję zestawić channel LACP pomiędzy nexusem 7000 a Juniperem M120, i niestety cały czas porty idą w stan suspended. Jak zapinam nexusa po LACP do cat-a 6500 idzie bez problemu, pojedynczy link bez skonfigurowanej agregacji również działa, juniper do cata6k też działa.

Na juniperze mam junos-a w wersji 13.3R9.13, a na n7k 6.2(14).
Może mieliście taką batalie ostatnio, z każdym innym urządzeniem n7k się dogaduje a tutaj już nie wiem o co chodzi.
