Chapter 41 Configuring PFC QoS
Configuring the Policy Map Class Trust State
You cannot attach a policy map that configures a trust state with the service-policy output command.
Note
To configure the policy map class trust state, perform this task:
Command
Router(config-pmap-c)# trust {cos | dscp |
ip-precedence}
Router(config-pmap-c)# no trust
When configuring the policy map class trust state, note the following information:

Configuring Policy Map Class Policing
When you configure policy map class policing, note the following information:
•
•
•
These sections describe configuration of policy map class policing:
•
•
Policing with the conform-action transmit keywords sets the port trust state of matched traffic to trust
Note
DSCP or to the trust state configured by a trust command in the policy map class.
Using a Named Aggregate Policer
To use a named aggregate policer, perform this task:
Command
Router(config-pmap-c)# police aggregate
aggregate_name
Router(config-pmap-c)# no police aggregate
aggregate_name
OL-4266-08
Enter the no trust command to use the trust state configured on the ingress port (this is the default).
With the cos keyword, PFC QoS sets the internal DSCP value from received or ingress port CoS.
With the dscp keyword, PFC QoS uses received DSCP.
With the ip-precedence keyword, PFC QoS sets DSCP from received IP precedence.
PFC QoS does not support the set-qos-transmit policer keyword.
PFC QoS does not support the set-dscp-transmit or set-prec-transmit keywords as arguments to
the exceed-action keyword.
PFC QoS does not detect the use of unsupported keywords until you attach a policy map to an
interface.

Purpose
Configures the policy map class trust state, which selects the
value that PFC QoS uses as the source of the initial internal
DSCP value.
Reverts to the default policy-map class trust state (untrusted).
Purpose
Configures the policy map class to use a previously defined
named aggregate policer.
Clears use of the named aggregate policer.
