Ethernet frame type question

Hi

Sorry if this isn't the place to ask this but I can't find a suitable group.
Some of the traffic on our network here seems to use ethernet frame types
0x0063 and 0x0068 but tcpdump doesn't know what they are and they don't
appear to be an official assignment. Has anyone come across these before?

If you're referring to the ethertype field, values <= 0x05DC (1500) are used
by ethernet 802.3 framing and indicate the length of the frame.
