Configuring Multicast Statistics Collection on Aggregated SONET Interfaces
T Series and TX Matrix routers support multicast statistics collection on aggregated SONET interfaces in both ingress and egress directions. The multicast statistics functionality can be configured on a physical interface thus enabling multicast accounting for all the logical interfaces below the physical interface.
The multicast statistics information is displayed only when the interface is configured with the multicast-statistics statement, which is not enabled by default.
Multicast statistics collection requires at least one logical interface is configured with family inet and/or inet6; otherwise, the commit for multicast-statistics will fail.
The multicast in/out statistics can be obtained via interfaces statistics query through CLI and via MIB objects through SNMP query.
To configure multicast statistics:
- Include the multicast-statistics statement at the [edit interfaces interface-name] hierarchy level.
An example of a multicast statistics configuration for an aggregated SONET interface follows:
To display multicast statistics, use the show interfaces interface-name statistics detail command.
