Chapter Cisco MWR 2941 Router Command Reference, Release 15.1(3)MR
police (two rates)
Usage Guidelines Configuring Priority with an Explicit Policing Rate
When you configure a priority class with an explicit policing rate, traffic is limited to the policer rate
regardless of congestion conditions. In other words, even if bandwidth is available, the priority traffic
cannot exceed the rate specified with the explicit policer.
Token Buckets
Two-rate traffic policing uses two token buckets—Tc and Tp—for policing traffic at two independent
rates. Note the following points about the two token buckets:
The Tc token bucket is updated at the CIR value each time a packet arrives at the two-rate policer.
The Tc token bucket can contain up to the confirm burst (Bc) value.
The Tp token bucket is updated at the PIR value each time a packet arrives at the two-rate policer.
The Tp token bucket can contain up to the peak burst (Be) value.
12.2(2)T The following keywords for the action argument were added:
set-clp-transmit
set-frde-transmit
set-mpls-exp-transmit
12.2(4)T This command expanded for the Two-Rate Policing feature. The cir and pir
keywords were added to accommodate two-rate traffic policing.
12.2(28)SB This command was integrated into Cisco IOS Release 12.2(28)SB, and the
set-dscp-tunnel-transmit and set-prec-tunnel-transmit keywords for the action
argument were added. These keywords are intended for marking Layer 2 Tunnel
Protocol Version 3 (L2TPv3) tunneled packets.
12.2(33)SRA The set-cos-inner-transmit keyword for the action argument was added when
using multipoint bridging (MPB) features on the Enhanced FlexWAN module, and
when using MPB on SPAs with the Cisco 7600 SIP-200 and Cisco 7600 SIP-400 on
the Cisco 7600 series router.
12.2SX This command is supported in the Cisco IOS Release 12.2SX train. Support in a
specific 12.2SX release of this train depends on your feature set, platform, and
platform hardware.
12.2(33)SRC This command was modified to support the Cisco 7600 series router equipped with
a Cisco Multilayer Switch Feature Card 3 (MSFC3).
12.4(15)T2 This command was modified to include support for marking Generic Routing
Encapsulation (GRE) tunneled packets.
Note For this release, marking GRE-tunneled packets is supported only on
platforms equipped with a Cisco MGX Route Processor Module (RPM-XF).
12.2(33)SB This command was modified to include support for marking GRE-tunneled packets,
and support for the Cisco 7300 series router was added.
12.4(20)T Support was added for hierarchical queueing framework (HQF) using the Modular
Quality of Service (QoS) Command-Line Interface (CLI) (MQC).
12.4(20)MR This command was integrated into Cisco IOS Release 12.4(20)MR.
12.2(33)MRA This command was integrated into Cisco IOS Release 12.2(33)MRA.
