0

0

Article ID: KB20644 KB Last Updated: 11 Jun 2021Version: 3.0
Summary:

You can modify the default queue assignment (forwarding class) and DSCP bits used in the ToS field of packets generated by the Routing Engine. By default, the forwarding class (queue) and DSCP bits are set according to those given in Default Routing Engine Protocol Queue Assignments.

This article describes how to change the Routing Engine outbound traffic defaults.

Solution:

To allow queue selection for all traffic generated by the Routing Engine (host), the selected queue must be configured properly. Configuration of specific DSCP code point bits for the ToS field of the generated packets is also allowed.

Transit packets are not affected; only the packets that originate on the Routing Engine are affected. By default, the forwarding class (queue) and DSCP bits are set according to those given in Default Routing Engine Protocol Queue Assignments
