To speed up the response of hosts to IGMP queries and avoid simultaneous timer expirations causing
IGMP report traffic bursts, you must properly set the maximum response time.
The maximum response time for IGMP general queries is set by the max-response-time command.
•
The maximum response time for IGMP group-specific queries is the same as the IGMP last-member
•
query interval, which is set by the last-member-query-interval command.
You can configure parameters for IGMP queries and responses either for the current VLAN in VLAN view
or globally for all VLANs in IGMP-snooping view. If the two configurations are made in both VLAN view
and IGMP-snooping view, the configuration made in VLAN view takes priority.
Configuring parameters for IGMP queries and responses globally
Step
1.
Enter system view.
2.
Enter IGMP-snooping view.
3.
Set the maximum response
time for IGMP general
queries.
4.
Set the IGMP last-member
query interval.
Configuring parameters for IGMP queries and responses in a VLAN
Step
1.
Enter system view.
2.
Enter VLAN view.
3.
Set the maximum response
time for IGMP general queries
in the VLAN.
4.
Set the IGMP last-member
query interval.
Configuring IGMP snooping port functions
Before you configure IGMP snooping port functions, complete the following tasks:
•
Enable IGMP snooping for the VLAN.
Determine the aging timer for dynamic router ports.
•
Determine the aging timer for dynamic member ports.
•
•
Determine the addresses of the multicast group and multicast source.
Setting aging timers for dynamic ports
When you set aging timers for dynamic ports, follow these guidelines:
