Most smart switches do port mirroring. But I've had the predecessor to that tap for a few years. It has always worked well.

Funds at my 9-5 are limited. Has anyone tried this and how well does it work? We plan on mirroring about 800 megs of traffic at peak. https://www.amazon.com/Dualcomm-1000Base-T-Ethernet-Regeneration-Netwo rk/dp/B0055M5JL8?ref_=ast_bbp_dp
I don't know if it still works on modern switches, but many years ago I was able to have Cisco LAN switches configured such that a single L2 MAC address could be statically associated with multiple interfaces (i.e. router interface). This made it possible to duplicate all traffic to destined to one station to appear on two (maybe more?) ports. You might try this also if you have an unused and available switch. John
