The following fields can be set: Parameter Description D-Link DES-3326S Layer 3 Switch MAC Address:[ ] VLAN Name Port: [ ] None Egress Forbidden Allows the entry of the MAC address of an end station that will be entered into the switch's static forwarding table. Allows the entry of the VLAN name of the VLAN the MAC address below is a member of − when adding a new entry to the table. Displays the VLAN name of the VLAN the MAC address is a member of − when editing an existing entry. Allows the entry of the port number on which the MAC address entered above resides. Specifies the port as being none. Specifies the port as being a source of multicast packets originating from the MAC address specified above. Forbidden Non-Member - specifies the port as not being a member of the VLAN and that the port is forbidden from becoming a member of the VLAN dynamically. Broadcast/Multicast Storm Control Broadcast and Multicast storms consist of broadcast or multicast packets that flood and/or are looped on a network causing noticeable performance degradation and, in extreme cases, network failure. The DES-3326S allows some control over broadcast/multicast storms by setting thresholds on the number of broadcast/multicast packets received (in thousands of packets per second or Kpps), and then following a user-specified course of action when this threshold is exceeded. To configure Broadcast/Multicast storm control: Click on the Forwarding folder, and then on the MAC Forwarding folder, and finally on the Broadcast/Multicast Storm Control link: Figure 8- 8. Broadcast/Multicast Storm Control Broadcast/Multicast storm control is applied to groups of ports on the DES-3326S. Group 1 contains ports 1 through 8. Group 2 contains ports 9 through 16. Group 3 contains ports 17 through 24. Group 4 and Group 5 contain the ports on the optional plug-in module. The Upper Threshold (Kpps) sets the rate of broadcast or multicast packets received on any of the ports in the corresponding port group that will trigger the action to be taken by the switch, as detailed below. A range of thousands of packets received per second (Kpps) between 0 and 255 can be specified. When any one of the ports contained within a given port group receives more broadcast or multicast packets per second than is specified in the Upper Threshold (Kpps) field, the switch will take the actions specified in the Broadcast Storm Mode, Multicast Storm Mode, and the Destination Lookup Fail pull-down menus. The Broadcast Storm Mode is Enabled or Disabled using the pull-down menu for the corresponding port group. When the Broadcast Storm Mode is enabled, and a port contained within the corresponding port group receives more broadcast packets 59
