Norman, Curious what Junos versions you hit this on, and what speed the uplinks were? When you say you standardize on running autonegotiation, are you adding this non-default portion to the config:
set interfaces xe-0/2/0 ether-options auto-negotiation And Juniper's recommendation is below, or to simply not add above? set interfaces xe-0/2/0 ether-options no-auto-negotiation We don't have any of these in production but have one as a test for a possible project, hence the curiosity. We've had a lab one running 18.2R3-S2.9 with LR SFP+ uplink with no issues- we have no ether-options set at all.
