The global configuration is valid on each interface.
The configuration on an interface is valid only for the specific interface. The configuration
on an interface takes precedence over the global configuration. If the IGMP querier is not
configured on the interface, the global configuration is used.
Configuring the global IGMP querier
1. Run:
system-view
The system view is displayed.
2. Run:
igmp
The IGMP view is displayed.
3. Run:
timer query interval
The interval for sending IGMP General Query messages is set.
By default, the interval for sending IGMP General Query messages is 60 seconds.
4. Run:
robust-count robust-value
The IGMP robustness variable is set.
When the S3700 starts, the S3700 sends General Query messages robust-value times.
The interval between the messages is 1/4 of the interval for sending IGMP General
Query messages. By default, the robustness variable is 2.
Configuring the IGMP querier on an interface
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
The S3700 uses this interface to communicate with hosts. On the S3700, VLANIF
interfaces and loopback interfaces support IGMP.
3. Run:
igmp timer query interval
The interval for sending IGMP General Query messages is set.
