Mirror/SPAN on Edge Router X

Lots of posts on this topic, none of them work.

 

Running Edge OS 1.9.1 on Edgerouter X

 

And there is nothing in the documentation...

 

My config is, eth1 (active link I want to monitor) and eth4 the port I have connected to the monitoring system.

 

Command is set interface ethernet eth1 mirror eth4

 

I have committed.  Hopefully reboot not required.

 

All I see on the monitoring system off eth4 are broadcast frames.  The data from eth1 is not being mirrored.

 

Anyone actually get this to work?

 

many thanks

-Steve

The ER-X is basically a switch with routing functionality. This is why the port-mirroring does not function properly, as this is done using software. On other models such as the ER-Lite you need to disable offloading to capture the data. The ER-X and ER-X-SFP use a different architecture. More info here:
