Modifying IPMS Parameters

Modifying IPMS Parameters
The table in "IPMS Default Values" on page 42-4
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 in seconds. The following
subsections describe how to configure a user-specified query interval value and restore it with the
ip multicast query-interval

Configuring the IGMP Query Interval

You can modify the IGMP query interval from 1 to 65535 in seconds by entering
ip multicast query-interval
seconds on the system if no VLAN is specified, you would enter:
-> ip multicast query-interval 60
You can also modify the IGMP query interval on the specified VLAN by entering:
-> ip multicast vlan 2 query-interval 60

Restoring the IGMP Query Interval

To restore the IGMP query interval to its default (i.e., 125 seconds) value on the system if no VLAN is
specified, use the ip multicast query-interval
-> ip multicast query-interval 0
Or, as an alternative, enter:
-> ip multicast query-interval
To restore the IGMP query interval to its default value.
You can also restore the IGMP query interval to its default value on the specified VLAN by entering:
-> ip multicast vlan 2 query-interval 0
Or, as an alternative, enter:
-> ip multicast vlan 2 query-interval
To restore the IGMP query interval to its default value.

Modifying the IGMP Last Member Query Interval

The default IGMP last member query interval (i.e., the time period to reply to an IGMP query message
sent in response to a leave group message) is 10 in tenths of seconds. The following subsections describe
how to configure the IGMP last member query interval and restore it by using the
ip multicast last-member-query-interval command.
