Modifying IPMS Parameters
The table in “IPMS Default Values” on page 25-2 lists default values for IPMS parameters. The following
sections describe how to use CLI commands to modify these parameters.
Modifying the IGMP Query Interval
The default IGMP query interval (i.e., the time between IGMP queries) is 125 seconds. The following
subsections describe how to configure a user-specified query interval value and restore it with the ip
multicast query-interval command.
Configuring the IGMP Query Interval
You can modify the IGMP query interval from 1 to 65535 seconds by entering ip multicast query-
interval followed by the new value. For example, to set the query interval to 60 seconds on the system if
no VLAN or SPB service is specified, you would enter:
-> ip multicast query-interval 60
You can also modify the IGMP query interval on the specified VLAN or SPB service by entering:
-> ip multicast vlan 2 query-interval 60
-> ip multicast service 10 query-interval 60
Restoring the IGMP Query Interval
To restore the IGMP query interval to its default value on the system if no VLAN or SPB service is
specified, use the ip multicast query-interval command by entering:
-> ip multicast query-interval 0
Or, as an alternative, enter the following command to restore the IGMP query interval to its default value:
-> no ip multicast query-interval
You can also restore the IGMP query interval to its default value on the specified VLAN or SPB service
by entering:
-> ip multicast vlan 2 query-interval 0
-> ip multicast service 10 query-interval 0
Or, as an alternative, enter the following commands to restore the IGMP query interval to its default value:
-> no ip multicast vlan 2 query-interval
-> no ip multicast service 10 query-interval
