Configuring the Switch
28
48-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet
Operation Mode Allows single or multiple hosts (clients)
to connect to an 802.1X-authorized port. (Options: Single-
Host, Multi-Host; Default: Single-Host)
Maximum Count (1-1024) The maximum number of
hosts that can connect to a port when the Multi-Host
operation mode is selected. The default value is 5.
Mode Sets the authentication mode to one of the
following options:
Auto Requires a dot1x-aware client to be authorized
by the authentication server. Clients that are not dot1x-
aware will be denied access.
Force-Authorized Forces the port to grant access to
all clients, either dot1x-aware or otherwise. (This is the
default setting.)
Force-Unauthorized Forces the port to deny access
to all clients, either dot1x-aware or otherwise.
Authorized Indicates the current status of the port:
Yes A connected client is authorized.
No No connected clients are authorized.
Blank Displays nothing when there is no connection
on a port.
Supplicant Indicates the MAC address of a connected
client.
Modify the parameters required using the drop-down
menus and fields provided for each port, then click Detail
to configure the 802.1X settings for that port.

Security > Ports Security
Port security is a feature that allows you to configure a
switch port with one or more device MAC addresses that
are authorized to access the network through that port.
When port security is enabled on a port, the Switch stops
learning new MAC addresses on the specified port when
it has reached a configured maximum number. Only
incoming traffic with source addresses already stored in
the dynamic or static address table will be accepted as
authorized to access the network through that port. If a
device with an unauthorized MAC address attempts to
use the switch port, the intrusion will be detected and the
Switch can automatically take action by disabling the port
and sending a trap message.
