This TigerStack 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
