Configuring the Switch
3-24
• PVID – The port VLAN ID (PVID) assigned to untagged frames received on the
interface. From the drop-down menu, choose the VLAN ID that will be assigned to
untagged frames received on the port. You cannot remove a port from VLAN 1
unless its PVID has been changed to something other than 1. You can only choose
“None” for the VLAN ID when the packet type is set to “Tagged Only.” Outgoing
packets are tagged unless the packet’s VLAN ID is the same as the PVID. When
the PVID is set to “None,” all outgoing packets are tagged. (Default: 1)
Note:
If you select “Tagged Only” mode for a port, it is recommended to set the PVID to
“None” as the standard configuration.
Web – Click VLANS, VLAN Port Configuration. Fill in the required settings for each
interface, click Apply.

802.1X
Network switches can provide open and easy access to network resources by
simply attaching a client PC. Although this automatic configuration and access is a
desirable feature, it also allows unauthorized personnel to easily intrude and
possibly gain access to sensitive network data. With IEEE 802.1X (802.1X), access
to all switch ports in a network can be centrally controlled from a server, which
means that authorized users can use the same credentials for authentication from
any point within the network.
802.1 X Setting
The IEEE 802.1X standard defines a port-based access control procedure that
prevents unauthorized access to a network by requiring users to first submit
credentials for authentication.
