1.2.5 Basic Functions
In general, the switch is responsible for switching both VLAN
tagged and untagged frames from a receiving port to one or
more transmitting ports. The switch performs multiple steps
during the switching process:
l
VLAN classification
l
Learning
l
Filtering
l
Forwarding
l
Aging
Below is additional information about tasks that the switch
performs during unicast and multicast switching.
UNICAST SWITCHING
VLAN CLASSIFICATION
When the switch receives a frame, it classifies the frame in one
of two ways:
l
If the frame is untagged, the switch classifies the frame to an
associated VLAN.
