Monitoring Optimized Multicast Packet Replication

Blocking and Limiting Multicast Traffic

Copyright © 2010, Juniper Networks, Inc.
You must specify an interface location, which is the identifier of another interface on
which the router has an assigned IPv6 address. This interface cannot be another
unnumbered interface.
Example
host1(config-if)#ipv6 unnumbered loopback 10
Use the no version to disable IPv6 processing on the interface.
See ipv6 unnumbered.
This section describes how to monitor hardware multicast packet replication.

Port Statistics

Use the show interfaces gigabitEthernet command to display port statistics for port 8.
For port 8, queue statistics have no direct relationship to any of the 8 ports because each
packet transmitting through the queue can be sent through 1 or more of the 8 physical
ports. For more information, see Monitoring Ethernet Interfaces in JunosE Physical Layer
Configuration Guide.

IP and VLAN Statistics

Use the show vlan subinterface command to display statistics for a VLAN interface
configured over port 8. For more information, see Monitoring Ethernet Interfaces in the
JunosE Physical Layer Configuration Guide.
Use the show ipv6 interface command to display statistics for an IPv6 interface configured
over port 8. For more information, see Monitoring IPv6 in JunosE IP, IPv6, and IGP
Configuration Guide.
Multicast traffic redirected by the hardware multicast packet replication feature is
displayed in the statistics for the IPv6 or VLAN interface over port 8, not the original IP
or VLAN interface over the physical port.
The statistics for the IPv6 or VLAN interface over port 8 reflect the number of packets
that passed through this interface destined for the hardware multicast packet replication
hardware. These statistics have no direct correlation to the number of packets being
transmitted from any of the physical ports.

MLD Statistics

Use the show ipv6 mld interface command to display statistics, including hardware
multicast packet replication status, for an IPv6 interface stacked over port 8. For more
information, see "Monitoring MLD" on page 190 in "Configuring Multicast Listener Discovery"
on page 175.
You can either block mroute creation, limit the multicast bandwidth admitted on an
outgoing interface, or limit outgoing interface creation on a port.
