[. . . ] All of the ports in the group must be members of the same VLAN. Further, the aggregated links must all be of the same speed and should be configured as full duplex. The configuration of the Master Port in the group becomes the configuration for all of the ports in the aggregation group. All configuration options ­ including the VLAN configuration ­ that can be applied to the Master Port are applied to the entire link aggregation group. Load balancing is automatically applied to the ports in the aggregated group, and a link failure within the group causes the network traffic to be directed to the remaining links in the group. 48 D-Link DES-3250TG Standalone Layer 2 Switch The Spanning Tree Protocol will treat a link aggregation group as a single link. STP will use the port parameters of the Master Port in the calculation of port cost and in determining the state of the link aggregation group. If two redundant link aggregation groups are configured on the switch, STP will block one entire group ­ in the same way STP will block a single port that has a redundant link. Figure 6- 13. Port Link Aggregation Group window To configure a link aggregation group, click Add on the Port Link Aggregation Group window above: Figure 6- 14. Port Link Aggregation Settings window The following fields can be set: Parameter Group ID(1-6) Description Allows the entry of a number used to identify the link aggregation group - when adding a new group. Displays the Group ID of the currently selected link aggregation group - when editing and existing entry. This field can be toggled between Enabled and Disabled. This is used to turn a link aggregation group on or off. This is useful for diagnostics, to quickly isolate a bandwidth intensive network device, or to have an absolute backup link aggregation group that is not under automatic control.

(Link IGMP IGMP Snooping To configure IGMP Snooping: From the Configuration menu, select the IGMP folder, and then click IGMP Snooping to open the following window: Figure 6- 15. Current IGMP Snooping Group Entries window To edit an IGMP Snooping entry on the switch, click the Modify button next to the entry on the Current IGMP Snooping Group Entries window: Figure 6- 16. IGMP Snooping Settings window The following fields can be set: Parameter VLAN ID Description Allows the entry of the VLAN ID for which IGMP Snooping is to be 50 D-Link DES-3250TG Standalone Layer 2 Switch configured. VLAN Name Allows the entry of the name of the VLAN for which IGMP Snooping is to be configured. Allows the entry of a value between 1 and 65535 seconds, with a default of 125 seconds. This specifies the length of time between sending IGMP queries.
