Hello everyone, I am experiencing traffic problems in the ethernet port on the protocol 814 randomly happens as if it were an attack, using the touch tool, I see that all traffic comes from Protocol 814, anyone know how to block this traffic?

It is not very useful to block this, as it is unrecognized traffic so it will not be processed anyway.
Check the MAC addresses to see who is sending it and ask them what it is.

based on my experience, its very difficult to trace who sending it and what add they aiming for

In general yes, but note that this traffic can only exist on a LAN segment!

I thank all the answers, this problem is taking me sleep, still have not found ways to trace the source of this traffic when q happens nothing can bar it unless removing the network cable. the graph below shows the times when the traffic occurs.
Very grateful to everyone!

At least tell us the source and destination MAC address of the traffic!

I could not identify mac-address that create this traffic out, what I could do to discover?

Use the Packet Sniffer

the packet sniffer can not find any package but the interface has a traffic of 68MB.

You have to configure and start it before you look at the data.

I set any direction and Ether1 interface

Then APPLY then START and wait a while, then STOP and look at PACKETS.

Found 03 mac-address the port on my router the neighbor router and a mac reset FF: FF: FF: FF: F, I could not FIND anything relevant, one thing I noticed is that the traffic is bound to vlan- ID = 1 and could not find ways to block this traffic, and the situation only gets worse as you can see in the print below.

I don't understand what you are trying to tell here.
Please just show a single packet as visible in a trace.

Anyway, don't try to block it in your router as that only wastes resources on it.
When you need to block it you need to find the source.
This should be possible on a LAN with managable switches.
