It might not be the best way, but if you set the ageing time of the bridge to 0, the bridge will forward the desired traffic.

I am trying to get the equivalent of promisc mode to pass all received

So I have a cisco switch with span port plugged into eh2 on my kvm host
which is centos.

I want the kvm host to forward all promisc traffic from the span port to
the guest running snort of tcpdump.

What would be the best way to do this?
