To determine whether IGMP tuning is needed in a network, you can configure the routing
device to record IGMP join and leave events. You can record events globally for the routing
device or for individual interfaces.
Table 42 on page 466 describes the recordable IGMP events.
Definition

Records IGMP leave events.

Records when IGMP accounting is disabled on an IGMP interface.

To enable IGMP accounting:
Enable accounting globally or on an IGMP interface. This example shows both options.

2.
descriptive filename, such as
[edit system syslog file igmp-events]
user@host# set any info
user@host# set match ".*RPD_IGMP_JOIN.* | .*RPD_IGMP_LEAVE.* |
.*RPD_IGMP_ACCOUNTING.* | .*RPD_IGMP_MEMBERSHIP_TIMEOUT.*"
Periodically archive the log file.

[edit system syslog file igmp-events]
user@host# set archive size 100000
user@host# set archive files 3
