Displaying a Policy Map

You can display a policy map with an interface summary for MPLS QoS classes or with the configuration
of all classes configured for all service policies on the specified interface.
Displaying a MPLS QoS Policy Map Class Summary
To display a MPLS QoS policy map class summary, perform this task:
Command
Router# show mls qos mpls [{interface interface_type
interface_number} | {module slot}
OL-11439-03
Fa3/27 5 In iptcp
Vl300 5 In
All 5 - Default
With MPLS, the exceed-action action command and the violate-action action command work
similarly to IP usage. The packet may get dropped or the EXP value is marked down. For
information on how these actions affect IP-to-IP traffic, see the
on page 38-61.
With MPLS, the set-dscp transmit action command and the set-prec-transmit action command set
the internal DSCP that is mapped into the CoS bits, which affects queueing, however, they do not
change the EXP value, except for imposition.
When swapping labels for received MPLS traffic with the PFC3B, you can mark down out-of-profile
traffic using the police command exceed-action policed-dscp-transmit and violate-action
policed-dscp-transmit keywords. The PFC3B does not mark in-profile traffic; when marking down
out-of-profile traffic, the PFC3B marks the outgoing topmost label. The PFC3B does not propagate
the marking down through the label stack.
With MPLS, the flow key is based on the label and EXP value; there is no flowmask option.
Otherwise, flow key operation is similar to IP-to-IP. See the
page 38-61.
You can use the police command to set the pushed label entry value to a value different from the
default value during label imposition.
When imposing labels onto the received IP traffic with the PFC3B, you can mark the EXP field using
the conform-action set-mpls-exp-imposition-transmit keywords.
During IP-to-MPLS imposition, IP ToS marking is not supported. If you configure a policy to mark
IP ToS, the PFC3B marks the EXP value.
