Hi VPP devs, I'm trying to figure out whether it's possible to set up port mirroring on a vhost-user port in VPP. The case I'm trying to make work is simple: I have traffic between two vms (using vhost-user ports) and I want to listen to that traffic, replicate it and send it somewhere else (to an interface, but preferably an ip).
I've looked into what's available in VPP and there is some support for SPAN, but doesn't seem to work with vhost-user interfaces (I wasn't able to configure it). In fact, it only seems to be configurable on physical interfaces. Is this accurate? Then there are clis for lawful intercept (set li), but the configuration doesn't seem to do anything. Is this supported? Is there some other way to achieve port mirroring on vhost-user interfaces in case the two above are not supported? It can be any unwieldy/hacky way (maybe setting something up with multicast?). Thanks, Juraj
