Examples
# Remove the dynamic group entries for all IGMP groups on all interfaces on the public network.
<Sysname> reset igmp group all
# Remove the dynamic group entries for all IGMP groups on VLAN-interface 100 on the public network.
<Sysname> reset igmp group interface vlan-interface 100 all
# Remove the dynamic group entry for the IGMP group 225.0.0.1 on VLAN-interface 100 on the public

Related commands
display igmp group
robust-count (IGMP view)
Use robust-count to set the global IGMP querier's robustness variable.
Use undo robust-count to restore the default.
Syntax
robust-count count
undo robust-count
Default
The global IGMP querier's robustness variable is 2.
Views
IGMP view
Predefined user roles
network-admin
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 the timeout
time for multicast groups.
This command and the igmp robust-count command 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 global IGMP querier's robustness variable to 5 on the public network.
<Sysname> system-view
[Sysname] igmp
