Single-Rate Color Marker for Traffic Policing
The Cisco 10000 series router supports a single-rate color marker to police traffic streams into groups
of conforming and nonconforming traffic. This marker is useful in marking packets in a packet stream
with different, decreasing levels of assurances (either absolute or relative). The marker can mark packets
with green, yellow, or red markings, which cause a specific action to occur. For example, a service might
discard all red packets because they exceed both the committed and excess burst sizes, forward yellow
packets as best effort, and forward green packets with a low drop probability.
The router provides two types of single-rate color markers: two-color and three-color.

Description
Sets the Frame Relay discard eligibility (DE) bit
and transmits the frame with the new DE setting.
Sets the Multiprotocol Label Switching (MPLS)
experimental (EXP) bits and transmits the packet
with the new MPLS EXP bit value setting. Valid
values are from 0 to 7.
Sets the MPLS experimental (EXP) bits in the
imposed label headers and transmits the packet
with the new MPLS EXP bit value setting. Valid
values are from 0 to 7.
The set-mpls-exp-imposition-transmit command
is available only on the PRE2 and replaces the
set-mpls-exp-transmit command.
Sets the precedence bit in the packet headers of
traffic streams aggregated into the same tunnel.
This enables the streams to receive a different level
of QoS processing at the outer ToS field's QoS
domain. Valid values are from 0 to 7.
Sets the IP precedence and transmits the packet
with the new IP precedence value setting. Valid
values are from 0 to 7.
Sets the QoS group value and transmits the packet
with the new QoS group value setting. Valid values
are from 0 to 99.
Transmits the packet. The packet is not altered.
In all releases prior to Cisco IOS Release 12.0(25)S and Release 12.3(7)XI, the router provides a
two-color marker. A two-color marker classifies traffic into two groups: traffic that conforms to the
specified committed information rate (CIR) and burst sizes, and traffic that exceeds either the CIR
or the burst sizes.
