Quick VLAN Walkthrough
802.1Q VLAN User’s Guide 3-39
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 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.
