i have ex 4300 switches and has a requirement of converting couple of ports to act like hub (i.e. all the traffic need a broadcasting) for connnecting couple of VOice recorders.
AFAIK, no-mac-learning may be knob to be used.
Can anyone confirm the same ?
Yes. If you want your switch to flood anything, essentially, you need not to learn any mac on any interface. Thus all traffic is unknown unicast, which will be flooded across the domain
