4.8 Security
The switch has the 802.1x port-based security feature. Only authorized hosts
are allowed to access the switch port. Traffic is blocked for hosts failed to
authenticate themselves. The authentication service is provided by a RADIUS
server or the local database in the switch.
The switch also support dynamic VALN assignment through 802.1x
authentication process. The VLAN information for the users/ports should be
configured in the authentication server properly before enabling this feature.
The switch has the port security feature. Users can use the port security feature
to restrict input to an interface by limiting and identifying MAC addressed of the
stations allowed to access the port. When you assign secure MAC addresses
to a secure port, the port does not forward with source addresses outside the
group of defined addresses.
4.8.1 Port Access Control
Port Access Control is used to configure various 802.1x parameters. 802.1x
uses either RADIUS server or local database(support MD5 authentication only)
to authenticate port users.
The first part is the Bridge(Global) settings:
Reauthentication: Once enabled, The switch will try to authenticate the port
user again when the re-authentication time is up.
Reauthentication Time: If ʻReauthenticationʼ is enabled, this is the time period
the switch uses to re-send authentication request to the port user.(see above)
Authentication Method: RADIUS or Local database can be used to
authenticate the port user.
