Make sure auto-negotiation is either enabled on both ends, or disabled on both ends.
On the Juniper side: set interfaces ge-x/y/z gigether-options no-auto-negotiation or delete interfaces ge-x/y/z gigether-options no-auto-negotiation Also, check the optics TX/RX levels on both ends to be sure they are within spec.
