The table in 

 lists default values for IPMSv6 parameters. The 

following sections describe how to use CLI commands to modify these parameters.

The default IPMSv6 query interval (i.e., the time between MLD queries) is 125 in seconds. The following 
subsections describe how to configure a user-specified query interval value and restore it by using the 

 command.

You can modify the MLD query interval from 1 to 65535 in seconds by entering 

 followed by the new value. For example, to set the MLD query interval to 

60 seconds on the system if no VLAN is specified, you would enter:

-> ipv6 multicast query-interval 160

You can also modify the MLD query interval on the specified VLAN by entering:

-> ipv6 multicast vlan 2 query-interval 160

To restore the MLD query interval to its default (i.e., 125 seconds) value on the system if no VLAN is 
specified, use the 

 command by entering:

-> no ipv6 multicast query-interval

You can also restore the MLD query interval on the specified VLAN by entering:

-> no ipv6 multicast vlan 2 query-interval

The default MLD last member query interval (i.e., the time period to reply to an MLD query message sent 
in response to a leave group message) is 1000 in milliseconds. The following subsections describe how to 
configure the MLD last member query interval and restore it by using the 

You can modify the MLD last member query interval from 1 to 65535 in milliseconds by entering 

 followed by the new value. For example, to set the MLD last 

member query interval to 600 milliseconds on the system if no VLAN is specified, you would enter:

-> ipv6 multicast last-member-query-interval 2200

You can also modify the MLD last member query interval on the specified VLAN by entering:

-> ipv6 multicast vlan 3 last-member-query-interval 2200
