Great 5 minute presentation! Definitely a topic that many of us in the industry take for granted and forget that people new to the industry may have never been exposed to these technologies.
Yet another great vid :-) I think spanning multiple entire vlans should be called out as a pretty big thing. Unless you are tapping a trunk port it’s hard to get that vis. Also worth noting that you should absolutely measure switch stats before and after implementing spanning. I have over seen a fairly large spanning deployment and for the most part regardless of vender (though mainly Cisco) we didn’t see an a real increase. Which depending on switch architecture is a reasonable assumption. But the one time we saw an increase- it really mattered
the performance of TAP and SPAN architectures is owed entirely to the manipulation of airborne particulate matter and single-surface reflective devices.
You can find various options in online stores. If 100 Mbps is enough, throwing star LAN tap suffices. If you need 1 Gbps, options cost around $200 and are powered. Typically unless you have a hub lying around these are cheaper choices in 2022, but I wouldn’t fully rely on the quality of a throwing star LAN tap. Definitely check reliability of any TAP before use.

Great presentation. Cisco SPAN may not capture 802.1Q tags on a trunk; a tap will.

What are people using as a tap, it looks like a simple hub switch? Just wondering if it's something special.
