show multicast statistics

Syntax

Description

Display IP multicast statistics.

Options

none

Display multicast statistics for all supported address families for all routing instances.

inet | inet6

(Optional) Display multicast statistics for IPv4 or IPv6 family addresses, respectively.

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 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.
