At the moment, it looks to be coming from Mankato, unless somebody
can tell me I'm reading things wrong.

The logs are filling up with

That MAC address is learned from Mankato's remote 10G link

But, I'm not getting an extraordinary level of input traffic from there.

Juniper PR695200 says this error message can be harmless though, so I'm not
