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

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: 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.
