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.

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]
  [QoS bandwidth: bps]
  RPF route: addr/mask, incoming interface
             neighbor address, owner route-owner
  Incoming interface list:
      Interface (addr/mask), State/Owner [(RPF IIF)]
  Outgoing interface list:
      Interface (addr/mask), State/Owner, Uptime/Expires
(10:0:0:1:1::, ff0e::1) uptime 0 01:05:23
  Admission bandwidth: 
  RPF route: 10:0:0:1::/64, incoming interface ATM2/3.1001
             neighbor 10:0:0:1::1, owner Local
  Incoming interface list:
      ATM2/3.1001 (10:0:0:1::1/64), Accept/Pim (RPF IIF)
  Outgoing interface list:
      ATM2/0.200 (21:2:2:21::2:1/60), Forward/Pim, 0 01:05:23/never
  Statistics:
      Received   : 346 pkts, 22144 bytes
      Forwarded  : 346 pkts, 22144 bytes
      Rcvd on OIF: 0 pkts
(10:0:0:1:2::, ff0e::1) uptime 0 01:05:23
  RPF route: 10:0:0:1::/64, incoming interface ATM2/3.1001
             neighbor 10:0:0:1::1, owner Local
  Incoming interface list:
      ATM2/3.1001 (10:0:0:1::1/64), Accept/Pim (RPF IIF)
  Outgoing interface list:
      ATM2/0.200 (21:2:2:21::2:1/60), Forward/Pim, 0 01:05:26/never
  Statistics:
      Received   : 346 pkts, 22144 bytes
      Forwarded  : 346 pkts, 22144 bytes
      Rcvd on OIF: 0 pkts

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.
