show multicast snooping statistics

Syntax

show multicast snooping statistics
<instance instance-name>
<interface interface-name>
<logical-system (all | logical-system-name)>

Release Information

Command introduced in JUNOS Release 8.5.

Description

Display IP multicast snooping statistics.

Options

none — Display multicast snooping statistics for all supported address families for all routing instances on all logical systems.

instance instance-name — (Optional) Display statistics for a specific routing instance.

interface interface-name — (Optional) Display statistics for a specific interface.

logical-system (all | logical-system-name) — (Optional) Perform this operation on all logical systems or on a particular logical system.

Additional Information

The input and output interface multicast snooping statistics are consistent, but not timely. They are constructed from the forwarding statistics, which are gathered at 30-second intervals. Therefore, the output from this command always lags the true count by up to 30 seconds.

Field Name

Field Description

Routing-instance

Name of the routing instance. (Displayed when multicast is configured within a routing instance.)

Family

Protocol family for which multicast statistics are displayed: INET or INET6.

Interface

Name of the interface for which statistics are being reported.

Routing Protocol

Primary multicast protocol on the interface: PIM, DVMRP for INET, or PIM for INET6.

Mismatch

Number of multicast packets that did not arrive on the correct upstream interface.

Kernel Resolve

Number of resolve requests processed by the primary multicast protocol on the interface.

Resolve No Route

Number of resolve requests that were ignored because there was no route to the source.

In Kbytes

Out Kbytes

Total accumulated outgoing packets (in KB) since the last time the clear multicast snooping statistics command was issued.

Mismatch error

Number of mismatches that were ignored because of internal errors.

Mismatch No Route

Number of mismatches that were ignored because there was no route to the source.

Routing Notify
