show multicast snooping statistics
Syntax
Release Information
Command introduced in Junos OS Release 8.5.
Description
Display IP multicast snooping statistics.
Options
- none
Display multicast snooping statistics for all supported address families for all routing instances.
- instance instance-name
(Optional) Display statistics for a specific routing instance.
- interface interface-name
(Optional) Display statistics for a specific interface.
- logical-system (all | logical-system-name)
(Optional) Perform this operation on all logical systems or on a particular logical system.
Additional Information
The input and output interface multicast snooping statistics are consistent, but not timely. They are constructed from the forwarding statistics, which are gathered at 30-second intervals. Therefore, the output from this command always lags the true count by up to 30 seconds.
