Because it is not an IP packet. It is an AppleTalk packet.

sercom appears to be a company selling measurement instruments. Maybe
you have such equipment in your network.  Maybe for some weird reason
these devices implement AppleTalk?

You should then make documenting your network topology your highest priority.
You should ALWAYS have a fully documented topology diagram with
detailed and accurate and up to date showing every single wire.

If you dont want to follow the cables what you can do and IFF you are
ABSOLUTELY sure the device is not vital for running your production
network (like being the uplink router):
Pull that cable from the switch and wait for someone to start screaming.
