MAC Address & VLAN ID
The MAC address and VLAN ID that is seen on this port. If no MAC addresses are
learned, a single row stating "No MAC addresses attached" is displayed.
Status
Indicates whether the corresponding MAC address is blocked or forwarding. In the
blocked state, it will not be allowed to transmit or receive traffic.
Time of Addition
Shows the date and time when this MAC address was first seen on the port.
Age/Hold
If at least one user module has decided to block this MAC address, it will stay in the
blocked state until the hold time (measured in seconds) expires. If all user modules
have decided to allow this MAC address to forward, and aging is enabled, the Port
Security module will periodically check that this MAC address still forwards traffic. If
the age period (measured in seconds) expires and no frames have been seen, the
MAC address will be removed from the MAC table. Otherwise a new age period will
begin.
If aging is disabled or a user module has decided to hold the MAC address indefinitely,
a dash (-) will be shown.
Buttons

5.3.1 Network Access Server Configuration
This page allows you to configure the IEEE 802.1X and MAC-based authentication
system and port settings.
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. One or more central servers, the backend servers, determine
whether the user is allowed access to the network. These backend (RADIUS) servers
