HP 5900 series Command Reference

Parameters
count: Sets an IGMP querier's robustness variable in the range of 1 to 255.
Usage guidelines
The IGMP querier's robustness variable defines the number of times to retransmit queries if packet loss
occurs. A higher robustness variable makes the IGMP querier more robust, but it increases timeout time
for multicast groups.
This command and the robust-count command in IGMP view have the same function but different
effective ranges:
• The robust-count command in IGMP view takes effect on all interfaces.
• The igmp robust-count command takes effect on the current interface.
For an interface, the igmp robust-count command takes priority over the robust-count command in IGMP
view.
Examples
# Set the IGMP querier's robustness variable to 5 on VLAN-interface 100.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] igmp robust-count 5
