Switch flood frame
The learning process of transparent bridging requires that the switch receive a frame from a device before unicast frames can be forwarded to it. Before any such transmission is received, unicast flooding is used to assure transmissions reach their intended destination. This is normally a short-lived condition as … Prikaži več In computer networking, a unicast flood is when a switch receives a unicast frame and treats it as a broadcast frame, flooding the frame to all other ports on the switch. Prikaži več The term unicast refers to a one-to-one transmission from one point in the network to another point. Conventionally, unicast is … Prikaži več When a network is experiencing unicast flooding, network performance is degraded. Here is a graph of a bridge before and after adjusting the size of the bridge address cache: 80% of the frames were flooded out never to be received by … Prikaži več Blocking unicast floods on a Cisco switch is easy to do, but it is not enabled by default. After ensuring that timeouts and/or security features have been configured to … Prikaži več • Broadcast, unknown-unicast and multicast traffic Prikaži več SpletSince the MAC address is listed in the MAC address table, the switch forwards the frame only to the port that connected to the frame’s destination (Fa0/2 in our case). Note that, however, if the MAC address was not found, the switch would flood the frame out all other ports (Fa0/2, Fa0/3, Fa0/4), except the port the frame was received on (Fa0/1).
