2To switch to an alternate port if the root port fails, select Enable Uplink Fast.

3To enable the backbone fast convergence feature, select Enable Backbone Fast.

4Click Save.

Changing VLAN IGMP Internet Group Management Protocol (IGMP) snooping controls multicast Settings traffic on a WX by forwarding packets for a multicast group only on the

ports that are connected to members of the group. IGMP is especially useful for WLANs because bandwidth is relatively constrained. The WX listens for multicast packets and maintains a table of multicast groups, as well as their sources and receivers, based on the traffic. IGMP snooping is enabled by default.

You can configure IGMP snooping parameters and enable or disable the feature on an individual VLAN basis.

The current software version supports IGMP versions 1 and 2.

To configure IGMP snooping:

1Access the VLAN table:

a Select the Configuration tool bar option.

b In the Organizer panel, click the plus sign next to the WX switch. c Click the plus sign next to System.

d Select VLANs.

2In the Content panel, select the VLAN.

3In the Task List panel, select Configure IGMP.

4To enable IGMP snooping, select Enable. To disable IGMP snooping, clear Enable. By default, IGMP snooping is enabled.

5In the Version list, select Version 1 or Version 2 of IGMP.

6If IGMP queriers are not on the subnet (for example, multicast routers), select Querier Enabled.

3Com recommends that you use the pseudo-querier only when the VLAN contains local multicast traffic that is not routed.

7In the Query Interval box, specify the interval (1 to 65,535 seconds) at which the WX switch sends general IGMP queries on behalf of multicast routers to advertise multicast groups. The default interval is 125 seconds.
