Monitoring PIM Interfaces for IPv4
Purpose
Display information about PIM interfaces. Specify no keywords or variables to view information about all PIM interfaces.
Specify the summary keyword to view the number of configured, enabled, and disabled PIM dense mode, PIM sparse mode, and PIM sparse-dense mode interfaces.
Specify the count keyword to view the number of multicast packets that the interface has sent and received.
Action
To display information about PIM interfaces. Specify no keywords or variables to view information about all PIM interfaces:
