Configuring MLD Snooping Queries (CLI)
Beginning in privileged EXEC mode, follow these steps to configure MLD snooping query characteristics
for the switch or for a VLAN:
DETAILED STEPS
Command or Action
Step 1
configure terminal
Example:
Switch# configure terminal
Step 2
ipv6 mld snooping robustness-variable value
Example:
Switch(config)# ipv6 mld snooping
robustness-variable 3
Step 3
ipv6 mld snooping vlan vlan-id
robustness-variable value
Example:
Switch(config)# ipv6 mld snooping vlan 1
robustness-variable 3
Step 4
ipv6 mld snooping last-listener-query-count
count
Example:
Switch(config)# ipv6 mld snooping
last-listener-query-count 7
Step 5
ipv6 mld snooping vlan vlan-id
last-listener-query-count count
Example:
Switch(config)# ipv6 mld snooping vlan 1
last-listener-query-count 7
Step 6
ipv6 mld snooping last-listener-query-interval
interval
Example:
Switch(config)# ipv6 mld snooping
last-listener-query-interval 2000
Step 7
ipv6 mld snooping vlan vlan-id
last-listener-query-interval interval
Purpose
Enters global configuration mode.
(Optional) Sets the number of queries that are sent before switch
will deletes a listener (port) that does not respond to a general query.
The range is 1 to 3; the default is 2.
(Optional) Sets the robustness variable on a VLAN basis, which
determines the number of general queries that MLD snooping sends
before aging out a multicast address when there is no MLD report
response. The range is 1 to 3; the default is 0. When set to 0, the
number used is the global robustness variable value.
(Optional) Sets the number of MASQs that the switch sends before
aging out an MLD client. The range is 1 to 7; the default is 2. The
queries are sent 1 second apart.
(Optional) Sets the last-listener query count on a VLAN basis. This
value overrides the value configured globally. The range is 1 to 7;
the default is 0. When set to 0, the global count value is used.
Queries are sent 1 second apart.
(Optional) Sets the maximum response time that the switch waits
after sending out a MASQ before deleting a port from the multicast
group. The range is 100 to 32,768 thousands of a second. The
default is 1000 (1 second).
(Optional) Sets the last-listener query interval on a VLAN basis.
This value overrides the value configured globally. The range is 0
