Figure 14: Example output from the SHOW SWITCH FILTER command.
The destination MAC address of a frame to be forwarded is checked against
the Forwarding Database. If there is no entry for the destination address the
frame is transmitted on all ports, except the port on which the frame was
received, which are in the ‘Forwarding’ state. This process is referred to as
flooding. If an entry is found in the Forwarding Database, but the entry is not
marked as ‘Forwarding’ or the entry points to the same port the frame was
received on, the frame is discarded. Otherwise, the frame is transmitted on the
port specified by the entry in the Forwarding Database.
A dynamic entry is automatically deleted from the Forwarding Database when
its ageing timer expires.
Quality of Service
The switch hardware has a number of Quality of Service (QOS) egress queues
that can be used to give priority to the transmission of some frames over other
frames on the basis of their user priority tagging. The user priority field in an
incoming frame (with value 0 to 7) determines which of the eight priority levels
the frame is allocated. When a frame is forwarded, it is sent to a QOS egress
queue on the port determined by the mapping of priority levels to QOS egress
queues. All frames in the first QOS queue are sent before any frames in the
second QOS egress queue, and so on, until frames in the last QOS egress queue,
