Use the ipv6 mld snooping robustness-variable global configuration command on the switch stack or
on a standalone switch to configure the number of IP version 6 (IPv6) Multicast Listener Discovery
(MLD) queries that the switch sends before deleting a listener that does not respond, or enter a VLAN
ID to configure on a per-VLAN basis. Use the no form of this command to reset the variable to the
default settings.
ipv6 mld snooping [vlan vlan-id] robustness-variable integer_value
no ipv6 mld snooping [vlan vlan-id] robustness-variable
This command is available only if you have configured a dual IPv4 and IPv6 Switch Database
Management (SDM) template on the switch.
vlan vlan-id
(Optional) Configure the robustness variable on the specified VLAN. The
VLAN ID range is 1 to 1001 and 1006 to 4094.
integer_value
The range is 1 to 3.
The default global robustness variable (number of queries before deleting a listener) is 2.
The default VLAN robustness variable (number of queries before aging out a multicast address) is 0,
which means that the system uses the global robustness variable for aging out the listener.
Global configuration
Release
12.2(53)SE2
To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 {default | vlan)
global configuration command and reload the switch.
Robustness is measured in terms of the number of MLDv1 queries sent with no response before a port
is removed from a multicast group. A port is deleted when there are no MLDv1 reports received for the
configured number of MLDv1 queries. The global value determines the number of queries that the
switch waits before deleting a listener that does not respond and applies to all VLANs that do not have
a VLAN value set.
The robustness value configured for a VLAN overrides the global value. If the VLAN robustness value
is 0 (the default), the global value is used.
VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used
in MLD snooping.
