Port 1 is already set to unused, and not the topic at hand anyway.
port 1 {
number-of-sub-ports 8;
unused;
speed 50g;
A 4x100 config is valid per the port checker, and is configured, yet doesn't work, thus the original question.

Hi Brian,
According to the Port Checker, the config is invalid:
Configuration Status:
Invalid
Validation Errors:
- With 8x50GE configured on the port 0, port 1 should be configured as unused.
Please see: https://apps.juniper.net/port-checker/qfx5220-32cd/
Best regards,
Roland.

Trying to break out the QDD-4X100G-2P5M to a Mellanox Q56 100G switch. Config is below (attempting to use port 5, tried 3 prior, and a number of others with no nearby port usage) . I've tried manually setting FEC types to every variant on both sides(and disabling for testing purposes), and still no luck. The same cable breaks out out from a Cisco to the same Mellanox Q56 100G with no issue. What am I missing? The OS version supports the breakout config.
