diffserv-mode(MTI interface view)

Function

The diffserv-mode command configures a differentiated service (Diff-Serv) mode for forwarding multicast packets on an MTunnel interface (MTI).

The undo diffserv-mode command restores the default Diff-Serv mode for forwarding multicast packets on an MTunnel interface.

By default, the Uniform Diff-Serv mode is adopted for forwarding multicast packets on an MTunnel interface.

Format

diffserv-mode { pipe service-class color | uniform }

undo diffserv-mode

Parameters

Parameter	Description	Value
pipe	Indicates that the Pipe Diff-Serv mode is adopted.	-
service-class	Specifies the service type when a multicast packet enters the public network from the private network.	The value can be: af1 af2 af3 af4 be cs6 cs7 ef
color	Specifies the color of a multicast packet transferred from a private network to a public network. The color marks the discarding priorities of the packet.	The value can be: green red yellow
uniform	Indicates that the Uniform Diff-Serv mode is adopted.	-

Usage Guidelines

Usage Scenario

The command is applicable only to the ingress PE. When you configure a Diff-Serv mode, note the following:

To enable the MTunnel interface to differentiate service priorities when forwarding multicast packets, set the Diff-Serv mode to Uniform.
To disable the MTunnel interface from differentiating service priorities when forwarding multicast packets, set the Diff-Serv mode to Pipe.

Configuration Impact

The service types for a multicast packet transferred from a private network to a public network are configured as follows:

To transmit the signaling protocol, set the service type to cs7 or cs6.
To ensure the low latency, set the service type to ef.
To ensure the bandwidth key data, set the service type to af4, af3, af2, or af1.
To ensure the best effort delivery without strict QoS guarantee, set the service type to be.
The preceding service types are listed by the sending priority in a descending order.
For the colors of the packets sent from private network to the public network, they are arranged by the discard priority in an ascending order, that is, green, yellow, and red.

Example

# Configure the Diff-Serv mode for forwarding multicast packets on the MTunnel interface as Pipe, the service type as af1, and the color as green.
