display multicast egress statistics

Function

The display multicast egress statistics command displays statistics about downstream Layer 3 IPv4 multicast packets.

Format

display multicast egress statistics [ vpn-instance vpn-instance-name ] source-address group-address slot slot-id

display multicast egress statistics slot slot-id

Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Specifies a VPN instance name.	The value is a string of 1 to 31 characters.
source-address	Specifies a multicast source address.	The value is in dotted decimal notation.
group-address	Specifies a multicast group address.	The value ranges from 224.0.1.0 to 239.255.255.255, in dotted decimal notation.
slot slot-id	Specifies a slot ID. The value range varies with the hardware of the router.	The value is a string of 1 to 15 characters, spaces not supported.

Usage Guidelines

Usage Scenario

After enabling a device to collect statistics about downstream Layer 3 IPv4 multicast packets, run the display multicast egress statistics command to check statistics about downstream Layer 3 IPv4 multicast packets.

In a source clone scenario, if the pre-cloning source address is S, the post-cloning source addresses are S1 and S2, and the multicast group address is G, the query methods are as follows:

Transmit end: run the display multicast forwarding-table command based on the (S, G) entry to query statistics about upstream Layer 3 IPv4 multicast packets, and run the display multicast egress statistics command based on the (S, G) entry to query statistics about downstream Layer 3 IPv4 multicast packets.
Receive end: run the display multicast forwarding-table command based on the (S1, G) and (S2, G) entries to query statistics about upstream Layer 3 IPv4 multicast packets, and run the display multicast egress statistics command based on the (S, G) entry to query statistics about downstream Layer 3 IPv4 multicast packets.

Prerequisites

The function of collecting statistics about downstream Layer 3 IPv4 multicast packets has been enabled using the multicast egress statistics [ vpn-instance vpn-instance-name ] source-address group-address slot slot-id or multicast egress statistics enable slot slot-id command.

The display multicast egress statistics slot slot-id command is supported only by the admin VS.

Example

The actual command output varies according to the device. The command output here is only an example.
