F3726, F3211, F3174, R5135, R3816-HP Firewalls and UTM Devices Network Management Command Reference-6PW100

1047
Default command level
2: System level
Parameters
all: The first all specifies the IPv6 multicast groups created based on the configured MLD SSM mappings
on all interfaces, and the second all specifies all IPv6 multicast groups created based on the configured
MLD SSM mappings.
interface-type interface-number: Specifies an interface by its type and number.
ipv6-group-address: Specifies an IPv6 multicast group by its IPv6 address, in the form of FFxy::/16,
where x and y represent any hexadecimal number in the range of 0 to F.
ipv6-source-address: Specifies a multicast source by its IPv6 address.
prefix-length: Specifies the prefix length of the multicast source or multicast group address. For a multicast
source address, this argument has an effective value range of 0 to 128. For a multicast group address,
it has an effective value range of 8 to 128. The system default is 128 in both cases.
Examples
# Clear all IPv6 multicast group information created based on the configured MLD SSM mappings on all
interfaces.
<Sysname> reset mld ssm-mapping group all

robust-count (MLD view)
Use robust-count to configure the MLD querier's robustness variable globally.
Use undo robust-count to restore the default.
Syntax
robust-count robust-value
undo robust-count
Default
The MLD querier's robustness variable is 2.
Views
MLD view
Default command level
2: System level
Parameters
robust-value: Specifies an MLD querier's robustness variable, in the range of 2 to 5.
Usage guidelines
The MLD querier's robustness variable defines the maximum number of attempts for transmitting MLD
general queries, multicast-address-specific queries, or multicast-address-and-source-specific queries in
case of packet loss due to network problems. A greater value of the robustness variable makes the MLD
querier "more robust", but results in a longer IPv6 multicast group timeout time.
