H3C S7500E Series Ethernet Switches Chapter 3 IGMP Configuration Commands
3-17
Description
Use the igmp timer other-querier-present command to configure the IGMP other
querier present interval on the current interface.
Use the undo igmp timer other-querier-present command to restore the system
default.
By default, the IGMP other querier present interval is [ IGMP query interval ] times
[ IGMP querier robustness variable ] plus [ maximum response time for IGMP general
queries ] divided by two.
 Note:
The three parameters in the above-mentioned formula default to 60 (seconds), 2 and
10 (seconds) respectively, so the default IGMP other querier present interval = 60 × 2 +
10 / 2 = 125 (seconds).
Related commands: timer other-querier-present, igmp timer query, igmp
robust-count, igmp max-response-time, display igmp interface.
