Quick VLAN Walkthrough

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.
