Modifying IPMS Parameters
“IPMS Default Values” on page 24-3
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 in seconds. The following
subsections describe how to configure a user-specified query interval value and restore it with the
command.
Configuring the IGMP Query Interval
You can modify the IGMP query interval from 1 to 65535 in seconds by entering
followed by the new value. For example, to set the query interval to 60
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 value on the system if no VLAN is specified, use the
command by entering:
-> 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.
