I would like some advice for which model to buy which will do split horizon without a performance impact.
I would like to bridge some VLANs on a single physical port together, and then enable split horizon. Q-in-Q
I tried this a few years ago but performance was very bad as it disabled the hardware offload on the switch and used the CPU instead. Switch model CPUs apparantly very good.
Is there a way to do this in hardware while still keeping full speed throughput?
I was thinking maybe I am better to use a router for this task as they have much more powerful CPUs but as this device just needs to switch 4gbit/sec, add/remove VLAN tags, bridge some VLAN interfaces together and split-horizon'ing, I was thinking a switch would typically be better?
The split horizon thing has me worried so hoping you can provide some advice before I go and order something that wont work with hardware offload.
