Hmmm. Sounds like something isn't padding the Ethernet frame
to the minimum frame-length of 64 bytes, or is ignoring the
VLAN tag when calculating the minimum acceptable frame length.
MAC header 14
IP header 20
ICMP header 12
ICMP payload 17
---------------
Total 63
Check for runts on the J-6350 router, as well as verify that
frames are arriving. Also check to see if it still fails with
non-VLAN-tagged interface. And maybe put a sniffer on the
line to see if the frames are being padded, and by how much.
