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
