IGMP Accounting

The Internet Group Management Protocol (IGMP) accounting feature enables BNG to maintain a statistics
file to log the instances of subscriber joining, or leaving a multicast group. The file's format is:
harddisk:/usr/data/igmp/accounting.dat.<Node ID>.<YYMMDD>
where
• Node ID is the name of the node that generates the file; for example, RP/0/RSP0/CPU0.
• YY is the year, MM is the month, and DD is the day.
An example of the statistics file name is:
harddisk:/usr/data/igmp/accounting.dat.RP_0_RSP0_CPU0.101225
The statistics file is stored on the route processor (RP) that is active. If a failover event occurs, then a new file
is created on the new active RP, and no attempt is made to mirror the data between the active and the standby
RP. Thus, the statistics files must be retrieved from both the active and standby RPs.
By default, the IGMP Accounting feature adds one file each day. To avoid exhausting disk space, you can
specify in how many files, or for how many days, data should be retained, see
on page
maximum size of each file should be no more than 250 MB.
