in fact that there are different types of broadcast traffic, e.g.<br>
<br>
- link-local traffic: traffic which goes from one switch port to another <br>
and no further (loopback frames, LLDP, etc)<br>
- broadcast traffic<br>
- multicast traffic<br>
- unknown unicast traffic<br>
<br>
For a quarantine LAN, the best option is to use RX port monitoring to <br>
detect all incoming frames on the new network port. This is the only <br>
option that shows you all frames, not just Bcast/Ucast/Mcast traffic.<br>
<br>
On a production IXP, it's often a good idea to run a broadcast frame <br>
collector, e.g. ixp-watch (<a href="https://github.com/euro-ix/IXP-Watch" rel="noreferrer" target="_blank">https://github.com/euro-ix/IXP-Watch</a>). This <br>
will monitor for ongoing problems.<br>
