Sniffer Attix5 Other communication

Hi,
I use Attix5 Traffic monitor as packet sniffer. Few days ago some “Other” communication started to show in monitor. Does anyone know what the Other communication could be?
See the image in attachment.

Thanks

no one?

I am guessing the “Other” traffic is traffic that isn’t defined. i.e. it’s not HTTP / SMTP / FTP / SSH / etc, etc traffic, perhaps IGMP or IPV6 traffic, etc
