Enabling IP multicast route statistics

Enable the collection and display of IP multicast route statistics.

These statistics are not related to the interface (port) statistics. Rather, the statistics are displayed based on multicast group classification. By default, collection of multicast route statistics is disabled.

Note

Note

When you enable IP multicast route statistics on the Controller node of a DvR domain, the configuration is automatically pushed to the Leaf nodes within the domain.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Enable the collection of IP multicast route statistics.

    ip mroute stats enable

  3. Optional: Set the IP multicast route statistics to default.

    default ip mroute stats enable

  4. Optional: Disable the collection of IP multicast route statistics.

    no ip mroute stats enable

  5. View the IP multicast route statistics.

    show ip mroute stats [WORD<3-160> {A.B.C.D[,E.F.G.H][,...]}]

    Note

    Note

    The maximum number of multicast group IP addresses is 10.

Example

Enable the collection of IP multicast route statistics:

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch:1(config)#ip mroute stats enable

View the IP multicast route statistics:

Switch:1#show ip mroute stats

WORD<3-160> {A.B.C.D[,E.F.G.H][,...]}

Specifies the multicast group IP address for which to display statistics.

The group IP address is in one of the following formats: a single IP address or a series of IP addresses.

You can specify a maximum of 10 groups.

Job aid

The following table shows the field descriptions for viewing multicast route statistics.

Field

Description

GroupAddress

Specifies the multicast group IP address for which to show statistics.

SourceCounter

Specifies the number of sources associated with the multicast route record.

IngressPackets

Specifies the number of packets received for the associated IP address.

IngressBytes

Specifies the number of bytes received for the associated IP address.

AverageSize

Specifies the average packet length for the associated group IP address. This information indicates only the ingress packet length and is calculated using the formula: ingress packet/ingress byte.
