Monitoring Multicast Statistics
Purpose
Display statistics for packets received through multicast routes that the router has added to the multicast routing table and established on the appropriate line modules.
- You can specify a multicast group IP address or both a multicast group IP address and a multicast source IP address to display information about a particular multicast forwarding entry.
- You can use the active option to display information for the active multicast routes.
- You can specify the bandwidth threshold along with the active option to display information for the active multicast routes with admission bandwidth greater than the specified bandwidth threshold. The default bandwidth threshold is 4000 bps.
Action
To display statistics of the multicast routes added to the multicast routing table:
host1#show ip mroute statistics IP Multicast Routing Table

Uptime | Length of time that the (S,G) pair has been active, in days hours:minutes:seconds format |
Expires | Length of time for which the (S,G) pair will be active, in days hours:minutes:seconds format |
Admission bandwidth | Admission bandwidth (in bps) |
QoS bandwidth | QoS bandwidth (in bps) |
RPF Route | IP address and subnetwork mask of the RPF route |
Incoming interface | Type and specifier of the incoming interface for the RPF route |
neighbor address | IP address of the neighbor |

|
Incoming interface list | List of incoming interfaces on the router. Details include:
|
Outgoing interface list | List of outgoing interfaces on the router. Details include:
|
Statistics |
Note: The output shows statistics after the virtual router has added the multicast route to the multicast routing table and established the route on the appropriate line module. Statistics for interactions before the route is established on the line module are not displayed. |
Counts | Numbers of types of (S,G) mappings:
