Incoming
The Switch classifies packets coming in on a port based on their VLAN identifier (VID)—or lack of one. If
the packet has a VID, the Switch forwards the packet only to the ports for that VLAN.
●
VLAN tagging
If the packet does not have a VID, the Switch assigns one based on what it has learned. It inspects the
packet and places it in a VLAN based on what it learns. It assigns the packet to an existing VLAN in the
following order.
IP address
❍
network protocol type
❍
MAC address
❍
If there are no matches, the Switch tags the packet with the VID of the port it came in on.
❍
●
Learning
The Switch learns VLAN membership information by inspecting the source addresses and VLAN
classification of all incoming and outgoing packets and records this information in its forwarding database.
●
Filtering and forwarding
Based on the information found in the VLAN database and the port state, the Switch either forwards
packets to other ports or filters them.
