Configure IGMP Snooping

When enabled for IGMP snooping, the Switch can open or close a port to a specific Multicast group member based on IGMP messages sent from the device to the IGMP host or vice versa.

IGMP Snooping is disabled by default. To enable IGMP Snooping and configure settings, highlight IGMP Snooping Settings in the Multicasting Menu and press Enter.

Figure 6- 39. IGMP Snooping Menu

The user-changeable parameters for IGMP Snooping are as follows:

•IGMP Snooping State:<Disabled> – Toggle to Enabled to implement IGMP Snooping.

•Querier State: <Non-Querier> - Choose V1 Querier for version 1 querier, V2 Querier for version 2 querier, or Non-Querier.

•Robustness Variable: [2] - The Robustness Variable field allows an entry of 2 to 255. Adjust this variable according to expected packet loss. In other words, if packet loss is expected to be high, the Robustness Variable should be increased to accommodate increased packet loss.

•Query Interval: [125] - The Query field allows an entry between 1 and 9,999 seconds and defines the time between transmitting IGMP queries.

•Max Response: [10] - The Max-Response field allows an entry between 1 and 254 and defines the maximum time allowed before sending a response report to a query measured in units of 1/10 of a second. This is used to adjust the "leave latency", the time internal between the moment the last host leaves a group and when the routing protocol is notified there are no more members.

•Age-out Timer - Displays the time the Switch waits between IGMP queries.

Highlight APPLY and press Enter to apply the IGMP Snooping settings. Use the Save Changes menu to save the settings to NV-RAM.
