Each filter set includes a couple of rules. You have to attach the filter set to certain ports to make the filter work. 4. 8. 1 Filter Set You can create a filter set by giving a name, ID and a mode of rules. The switch defines two modes of rules, one is MAC mode and the other is IP mode. Only the same mode of rules can bundle together to form a filter set. Each mode has different fields to configure. For example, you can use IP mode rule to filter FTP packets. When you click on the Filter Set, the Filter Set page appears (Figure 38). First, create a filter set by typing a name and ID, then clicking on . button to select the set you want to edit or remove.

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 supports dynamic VLAN 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. 4. 9. 1 Port Access Control Port Access Control is used to configure various 802. 1x parameters. 802. 1x uses either RADIUS server or local database 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 'Reauthentication' 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. · Quiet Period: If authentication failed either from RADIUS or local database, the switch waits upon this time period before sending another authentication request to the port user. · Retransmission Time: If the port user failed to respond to authentication request from the switch, the switch waits upon this time period before sending another authentication request to the port user. [. . . ] subnet A subnet is a portion of a network. The subnet is distinguished from the larger network by a subnet mask which selects some of the computers of the network and excludes all others. The subnet's computers remain physically connected to the rest of the parent network, but they are treated as though they were on a separate network. subnet mask TCP TCP/IP A mask that defines a subnet.
