Modifying IPMS Parameters

The table in "IPMS Default Values" on page 23-2
sections describe how to use CLI commands to modify these parameters.

Modifying the Leave Timeout

The IPMS leave timeout is the delay in removing a group membership after a leave message has been
processed and/or received. The default IPMS leave timeout is 1 second. The following subsections
describe how to configure a user-specified leave timeout value and how to restore it with the
leave-timeout command.

Configuring the Leave Timeout

You can modify IPMS leave timeout from 0 to 4294967295 seconds by entering
timeout followed by the new value. For example, to set the leave timeout to 5 seconds you would enter:
-> ip multicast leave-timeout 5

Restoring the Leave Timeout

To restore the leave timeout to its default (i.e., 1 second) value you use the no form of the
leave-timeout command by entering:
-> ip multicast no leave-timeout

Modifying the Query Interval

The default IPMS 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 how to restore it with the
ip multicast query-interval

Configuring the Query Interval

You can modify the query interval from 0 to 4294967295 seconds by entering
interval followed by the new value. For example, to set the query interval to 60 seconds you would enter:
-> ip multicast query-interval 60

Restoring the Query Interval

To restore the query interval to its default (i.e., 125 seconds) value you use the no form of the
ip multicast query-interval
-> ip multicast no query-interval

Modifying the Membership Timeout

The default IPMS membership timeout (i.e., the time the switch will wait for an IGMP report before it
drops a member from a multicast group) is 260 seconds. The following subsections describe how to
configure a user-specified membership timeout value and how to restore it with the
membership-timeout
