mld robust-count
Use mld robust-count to set the MLD querier's robustness variable on an interface.
Use undo mld robust-count to restore the default.
Syntax
mld robust-count count
undo mld robust-count
Default
The MLD querier's robustness variable is 2.
Views
Interface view
Predefined user roles
network-admin
Parameters
count: Sets an MLD querier's robustness variable in the range of 1 to 255.
Usage guidelines
The MLD querier's robustness variable defines the number of times to retransmit MLD queries if packet
loss occurs. A higher robustness variable makes the MLD querier more robust, but it increases the timeout
time for IPv6 multicast groups.
This command and the robust-count command in MLD view have the same function but different effective
ranges:
• The robust-count command in MLD view takes effect on all interfaces.
• The mld robust-count command takes effect on the current interface.
For an interface, the mld robust-count command takes priority over the robust-count command in MLD
view.
Examples
# Set the MLD querier's robustness variable to 5 on VLAN-interface 100.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] mld robust-count 5
