Syntax

content_copy zoom_out_map
dscp-code-point value;

Hierarchy Level

content_copy zoom_out_map
[edit class-of-service host-outbound-traffic]

Description

Specify the value of the DSCP bits in the type of service (ToS) field of host outbound traffic (packets generated by the local Routing Engine) as they are placed in the default or specified output queue on all egress interfaces. This statement does not affect transit traffic or incoming traffic.

If you use the ping operational mode command with the tos type-of-servce option, the value specified in this configuration statement overrides the DSCP value you specify in the ping command.

Note:

With this configuration, QFX Series switches rewrite DSCP code points for all packets that are host-generated. EX Series switches and MX Series routers rewrite DSCP code points only if the packet L3 TOS value is not already set or is marked with the default code point.

Any DSCP rewrite rules configured on a 10-Gigabit Ethernet LAN/WAN PIC with SFP+ overwrite this DSCP value.

For egress interfaces hosted on MX Series routers, M120 routers, or Enhanced III FPCs in M320 routers, both Routing Engine sourced traffic and distributed protocol handler traffic are affected. For all other egress interfaces, only Routing Engine sourced traffic is affected.

Options

code-point

Six-bit DSCP code point value.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 8.4.

Support for distributed protocol handler traffic introduced in Junos OS Release 13.2.
