Table 97 IGMP Snooping Configuration controls
Control
Descriptions
IGMP on?
Enables or disables IGMP Snooping.
Set report timeout
Configures the timeout value for IGMP Membership Reports (host). Once the timeout
value is reached, the switch removes the host from its IGMP table, if the conditions
are met. The range is from 1 to 255 seconds. The default is 10 seconds.
Set multicast router timeout
Configures the timeout value for IGMP Membership Queries (Mrouter). Once the
timeout value is reached, the switch removes the multicast router from its IGMP table,
if the proper conditions are met. The range is from 1 to 255 seconds. The default is
255 seconds.
Set robust value or expected
packet loss on subnet
Configures the IGMP Robustness variable, which allows you to tune the switch for
expected packet loss on the subnet. If the subnet is expected to be lossy (high rate of
packet loss), increase the value. The range is from 2 to 10. The default value is 2.
Set query interval
Sets the IGMP router query interval, in seconds. The default value is 125.
Aggregate IGMP report
Enables or disables IGMP Membership Report aggregation.
Set Source IP for GSQ proxy
Configures the source IP address used as a proxy for IGMP Group Specific Queries.
Remove all VLANs from IGMP
Snooping
Removes all VLANs from the list of Snooping VLANs.
Configured VLANs
Lists the VLANs that can be assigned for IGMP Snooping.
Snooping VLANs
Enables or disables IGMP Snooping on selected VLANs.
Add: Adds selected VLANs to the Snooping VLANs list. To add a VLAN, select the
VLAN in the Configured VLANs list, and click Add.
Remove: Removes selected VLANs from the Snooping VLANs list.
Snooping VLANs without
Fstleave
Lists the Snooping VLANs that can be assigned for Fstleave processing.
Snooping VLANs with Fstleave
Enables or disables Fastleave processing. Fastleave allows the switch to immediately
remove a port from the IGMP port list, if the host sends a Leave message, and the
proper conditions are met. This command is disabled by default.
Add: Adds selected VLANs to the Snooping VLANs with Fstleave list. To add a VLAN,
select the VLAN in the Snooping VLANs without Fstleave list, and click Add.
Remove: Removes selected VLANs from the Snooping VLANs with Fstleave list.
IGMP Filters Configuration
To display the following form, select Layer 3 > IGMP > IGMP Filters (click the underlined text, not the folder).
This form summarizes IGMP filter parameters. Use IGMP filters to allow or deny a port to send and receive
multicast traffic.
