Disabling Mld Listener Message Suppression - Cisco 3032 Software Configuration Manual

Chapter 25 Configuring IPv6 MLD Snooping
This example shows how to set the MLD snooping global robustness variable to 3:
Switch# configure terminal
Switch(config)# ipv6 mld snooping robustness-variable 3
Switch(config)# exit
This example shows how to set the MLD snooping last-listener query count for a VLAN to 3:
Switch# configure terminal
Switch(config)# ipv6 mld snooping vlan 200 last-listener-query-count 3
Switch(config)# exit
This example shows how to set the MLD snooping last-listener query interval (maximum response time)
to 2000 (2 seconds):
Switch# configure terminal
Switch(config)# ipv6 mld snooping last-listener-query-interval 2000
Switch(config)# exit

Disabling MLD Listener Message Suppression

MLD snooping listener message suppression is enabled by default. When it is enabled, the switch
forwards only one MLD report per multicast router query. When message suppression is disabled,
multiple MLD reports could be forwarded to the multicast routers.
Beginning in privileged EXEC mode, follow these steps to disable MLD listener message suppression:
Command
Step 1 configure terminal
Step 2 no ipv6 mld snooping
listener-message-suppression
Step 3 end
Step 4
show ipv6 mld snooping
Step 5 copy running-config startup-config
To re-enable MLD message suppression, use the ipv6 mld snooping listener-message-suppression
global configuration command.
Displaying MLD Snooping Information
You can display MLD snooping information for dynamically learned and statically configured router
ports and VLAN interfaces. You can also display MAC address multicast entries for a VLAN configured
for MLD snooping.
To display MLD snooping information, use one or more of the privileged EXEC commands in
