monitoring only sg-1100

[networking71]

I upgrade recently to a 1 Gbit/s Internet connection. My SG-1100 doesn't unfortunately has the power to handle the connection. I would like to use it for bandwidth and flow monitoring (pfsense). Here is my current setup:

ISP Modem <-> managed switch <-> WAN Eero gateway
manged switch SPAN /Mirror port of all LAN traffic <-> Pfsense OPT port
PFSENSE LAN port : Gui /console access

There might be some package drop, but the bandwidth and flow monitoring is not even close to reality.
is there a way to configure the ports of the SG-1100 to achieve this. Does in my case the opt port needs a specific configuration. I set it currently to IPv4 and DHCP.
Thanks in advance

What are you running on the SG-1100 to log the traffic on the span port?

I'm not sure what you're trying there has ever been tested so I couldn't tell you what sort of performance you could expect there.

The OPT port would not need any config to monitor incoming packets, I would set that to 'none'.

Do you have pf disabled?
