    Switch Frame Flood - Flood limited to ports in same VLAN the frame was received on?

    David

      In further reading of the TSHOOT OCG I got into the mac table / broadcast storm section on layer 2, and this is the first time I recall the flood decision being discussed as only flooding out the ports in the same VLAN it was received on (except of course the port its received on), and wanted to confirm that this is the case?

       

      I guess I've only ever heard it discussed in a default behavior, with probably default vlans only (all ports in VLAN 1), so wanted to make absolutely sure that if there are a few different VLANs on a switch this changes the "flood out all ports except the one it rode in on" base switching decision?

       

      I know this is a noob question, but want to be completely clear on this point.

       

      Thank you!
