This TigerSwitch 10/100 supports Layer 2 switching and other
advanced features, which are described in this chapter.
Layer 2 Switching
When a frame enters a port, its destination MAC address is
checked in the address database to see which port leads to this
destination. If the destination address belongs to the incoming
port, the frame is dropped or “filtered” because it addressed to the
local segment. If the destination address if found on another port,
the frame is forwarded to that port and queued for output. But, if
the destination address is
not
found in the address database, the
frame is sent to one or more output ports based on the rules for
handling tagged or untagged VLAN frames.
If the source MAC address of the frame was not found in the
address database, it is recorded along with the incoming port
number where it entered the switch. This information is then used
to make later decisions for frame forwarding.
Switching involves the following steps:
◆
VLAN Classification
◆
Learning
◆
Filtering
◆
Forwarding
◆
Aging
