Multiple Span on 4112F-ON with OS10
In this test case I am testing to see if we can configure a Dell 4112F-ON with OS10 to create a one to many port configuration using SPAN.

Configure Device as TAP
Physical Configuration
For this configuration to work, we will use the management interface as the input interface for the tap. See image below. You will need to move your network cable over from your usual network to your traffic generator.
Problem
The way this worked on OPX was to use the Linux kernel module called TC. The net_sched module which supports ingress packet manipulation is not available on OS10. It could be reinstalled, but I didn't explore this option. Currently I don't have a working config on OS10.
Test with Mirror Ports
It looks like OS10 only supports one destination port on a port mirror. See the below.
