trust
Use the trust Policy-map Class Configuration mode command to configure
the trust state, which selects the value that QoS uses as the source of the
internal DSCP value. Use the no form of this command to return to the
default trust state.
Syntax
trust
cos-dscp
no trust
Parameters
cos-dscp—Specifies that if the packet is IP, then QoS acts as for dscp;
otherwise QoS acts as for cos.
Default Configuration
The default state is untrusted.
If the trust command is specified with no parameters, the default mode is
dscp.
Command Mode
Policy-map Class Configuration mode
User Guidelines
Use this command to distinguish the Quality of Service (QoS) trust behavior
for certain traffic from others. For example, incoming traffic with certain
DSCP values can be trusted. A class map can be configured to match and
trust the DSCP values in the incoming traffic.
Trust values set with this command supersede trust values set on specific
interfaces with the qos trust Interface Configuration mode command.
The trust command and the set Policy-map Class Configuration mode
command are mutually exclusive within the same policy map.
Policy maps that contain set or trust Policy-map Class Configuration mode
commands cannot be attached, or that have Access Control List (ACL)
classification to an egress interface by using the service-policy Interface
Configuration mode command.
