Enabling IGMP snooping
IGMP snooping works only when a multicast router that has been dynamically learned as a Querier exists in the VLAN. Even when IGMP snooping is enabled, if the VLAN does not hear a query from a multicast router, the group reports from the hosts are not processed.
To enable IGMP snooping:
- From the Device Manager menu bar, choose VLAN > VLANs.
| The VLAN dialog box opens with the Basic tab displayed. |
- Click the Snoop tab.
- In the Snoop tab, click the Enable text box.
- Select true.
