Well, that was an easy fix on my MX480s: set protocols lldp interface xe-0/0/1 disable
Now I'm not seeing CRC errors incrementing 2-3 times per minute on the EX3400s connected directly to the MX480s. I'm not excluding any protocols from MACsec--LLDP runs end-to-end between the EX3400s just fine. Check if the carrier is running LLDP or CDP or similar.
