Quick VLAN Walkthrough
This effectively completes the configuration of a single VLAN, assigning it to a port, and
configuring the switch to forward the frames received on that port to be forwarded with the VLAN
information included in the frame.
The Port VLAN List of any port on the device can also be checked at any time using the Port
Filtering Configuration screen. A list of all ports eligible to transmit frames for a given VLAN will
also be listed on the VLAN Forwarding Configuration screen. Each port can also be set to filter out
(drop) incoming frames that have VLAN tags that do not match with any of those in its Port
VLAN List, and also filter out all untagged frames received by the port. As a default neither
function is activated.
In the following last stage of this walkthrough, we will show how to display the Port VLAN List of
port 10 and set the port to filter out all untagged frames that it receives.
