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

Section titled “Configure Device as TAP”

Physical Configuration

Section titled “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

Section titled “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

Section titled “Test with Mirror Ports”

It looks like OS10 only supports one destination port on a port mirror. See the below.
