Figure 48: Authenticated Hosts Page

The Authenticated Hosts Page contains the following fields:

User Name — Lists the supplicants that were authenticated, and are permitted on each port.

Port — Displays the port number.

Session Time — Displays the amount of time (in seconds) the supplicant was logged on the port.

Authentication Method — Displays the method by which the last session was authenticated. The possible field values are:

–Remote — 802.1x authentication is not used on this port (port is forced-authorized).

–None — The supplicant was not authenticated.

–RADIUS — The supplicant was authenticated by a RADIUS server.

MAC Address — Displays the supplicant MAC address.

5.2.3 Configuring Traffic Control

This section contains information for managing both port security and storm control, and includes the following topics:

Managing Port Security

Enabling Storm Control

5.2.3.1 Managing Port Security

Network security can be increased by limiting access on a specific port only to users with specific MAC addresses. The MAC addresses can be dynamically learned or statically configured. Locked port security monitors both received and learned packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that port up to the point when it is locked. When a packet is received on a locked port, and the packet TP-Link source MAC address is not tied to that port (either it was learned on a different port, or it is unknown to the system), the protection mechanism is invoked, and can provide various options.

Unauthorized packets arriving at a locked port are either:

Forwarded

Discarded with no trap

Discarded with a trap

Shuts down the port

Locked port security also enables storing a list of MAC addresses in the configuration file. The MAC address list can be restored after the device has been reset.

Disabled ports are activated from the Port Security Page.
