Sx350x switch configuration

[360560]

I have a cisco 350x switch connected to the pc. I have two different devices that communicate with 10G ethernet outside. I want to connect these devices to the switch and monitor the traffic over the pc. What switch configuration should I do for this?

Hello @360560,

You need to monitor two interfaces towards PC's interface.

Utilize SPAN feature that allows you to copy traffic from one or more source ports and send it to a destination port, where the monitoring PC is connected.

Example where interfaces outside are gig1 and 2 and PC connected to gig 3:

config terminal
monitor session 1 source interface gigabitethernet1 both
monitor session 1 source interface gigabitethernet2 both
monitor session 1 destination interface gigabitethernet3

-- see SPAN/RSPAN chapter.

My main problem is that I cannot connect two devices to each other via the switch.I couldn't make the relevant configuration. Xg19 and xg20 are my ports.

This is not clear - if the device is in sniff mode its just Layer2 and start getting the traffic when you run sniffer.

or as i am thinking different here ?

My devices are FPGAs. When I connect ethernet channels directly without a switch, they communicate. When I connect the devices one by one to the PC without a switch, I can see the packets. But when I connect the devices via a switch, there is no communication.
