Monitoring IPv6 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 address or both a multicast group address and a multicast source 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 the statistics of the multicast routes added to the multicast routing table:

host#show ipv6 mroute statistics 
IPv6 Multicast Routing Table

(S, G) uptime d h:m:s[, expires d h:m:s]
  [Admission bandwidth: bps]

Meaning

Table 61 lists the show ipv6 mroute statistics command output fields.

Table 61: show ipv6 mroute statistics Output Fields

Field Name	Field Description
(S,G)	IPv6 addresses of the multicast source and the multicast group
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	IPv6 address and prefix of the RPF route
Incoming interface	Type and specifier of the incoming interface for the RPF route
neighbor address	IPv6 address of the neighbor
owner	Owner of the route: Local—route belonging to the local interface Static—Static route Other protocols—Route established by a protocol
Incoming interface list	List of incoming interfaces on the router. Details include: Type of interface and its specifier Action that the interface takes with packets: accept or discard Multicast protocol that owns the interface Time that the interface has been active in this multicast forwarding entry, in days hours:minutes:seconds format Time that the interface will cease to be active in this multicast forwarding entry, in days hours:minutes:seconds format
Outgoing interface list	List of outgoing interfaces on the router. Details include: Type of interface and its specifier Action that the interface takes with packets: Forward or Blocked (intf-adm-limit, join-intf-adm-limit, port-adm-limit, port-limit, port-priority-limit) Protocol running on the interface: PIM or MLD Time that the interface has been active in this multicast forwarding entry, in days hours:minutes:seconds format Time that the interface will cease to be active in this multicast forwarding entry, in days hours:minutes:seconds format
Statistics	Received—Number of packets and bytes that the virtual router received for this multicast route Forwarded—Number of packets and statistics that the virtual router has forwarded for this multicast route Rcvd on OIF—Number of packets and statistics that the virtual router has received on the OIF for this multicast route Note: The display 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.
