Single-Rate Two-Color Policer Overview

Single-rate two color policing enforces a configured rate oftraffic flow for a particular service level by applying implicit orconfigured actions to traffic that does not conform to the limits.When you apply a single-rate two-color policer to the input or outputtraffic at an interface, the policer meters the traffic flow to therate limit defined by the following components:

• Bandwidth limit—The average number of bits per secondpermitted for packets received or transmitted at the interface. Youcan specify the bandwidth limit as an absolute number of bits persecond or as a percentage value from 1 through 100. If a percentagevalue is specified, the effective bandwidth limit is calculated asa percentage of either the physical interface media rate or the logical interface configured shaping rate.

• Packets per second (pps) limit (MX Series with MPC only)–Theaverage number of packets per second permitted for packets receivedor transmitted at the interface. You specify the pps limit as an absolutenumber of packets per second.

• Burst-size limit—The maximum size permitted forbursts of data.

• Packet burst limit–

For a traffic flow that conforms to the configured limits (categorizedas green traffic), packets are implicitly marked with a packet losspriority (PLP) level of Note

There is a finite buffer space for an interface. In general,the estimated total buffer depth for an interface is about 125 ms.

For a traffic flow that conforms to the configured limits (categorizedas green traffic), packets are implicitly marked with a packet losspriority (PLP) level of low and are allowed to pass through the interfaceunrestricted.

For a traffic flow that exceeds the configured limits (categorizedas red traffic), packets are handled according to the traffic-policingactions configured for the policer. This example discards packetsthat burst over the 15 KBps limit.

To rate-limit Layer 3 traffic, you can apply a two-color policerin the following ways:

• Directly to a logical interface, at a specific protocollevel.

• As the action of a standard stateless firewall filterthat is applied to a logical interface, at a specific protocol level.This is the technique used in this example.

To rate-limit Layer 2 traffic, you can apply a two-color policeras a logical interface policer only. You cannot apply a two-colorpolicer to Layer 2 traffic through a firewall filter.

You can choose either bandwidth-limit or bandwidthpercent within the policer, as they are mutually exclusive. You cannotconfigure a policer to use bandwidth percent for aggregate, tunnel,and software interfaces.

In this example, the host is a traffic generator emulating awebserver. Devices R1 and R2 are owned by a service provider. Thewebserver is accessed by users on Device Host2. Device Host1 willbe sending traffic with a source TCP HTTP port of 80 to the users.A single-rate two-color policer is configured and applied to the interfaceon Device R1 that connects to Device Host1. The policer enforcesthe contractual bandwidth availability made between the owner of thewebserver and the service provider that owns Device R1 for the webtraffic that flows over the link that connects Device Host1 to DeviceR1.

In accordance with the contractual bandwidth availability madebetween the owner of the webserver and the service provider that ownsDevices R1 and R2, the policer will limit the HTTP port 80 trafficoriginating from Device Host1 to using 700 Mbps (70 percent)of the available bandwidth with an allowable burst rate of 10 x theMTU size of the gigabit Ethernet interface between the host DeviceHost1 and Device R1.

In a real-world scenario you would probably also ratelimit traffic for a variety of other ports such as FTP, SFTP, SSH,TELNET, SMTP, IMAP, and POP3 because they are often included as additionalservices with web hosting services.

You need to leave some additional bandwidth availablethat is not rate limited for network control protocols such as routingprotocols, DNS, and any other protocols required to keep network connectivityoperational. This is why the firewall filter has a final accept conditionon it.

Topology

This example uses the topology in Figure 1.

Configuration

CLI Quick Configuration

To quickly configure this example,copy the following commands, paste them into a text file, remove anyline breaks, change any details necessary to match your network configuration,and then copy and paste the commands into the CLI at the

Step-by-Step Procedure

1. Configure the device interfaces.
2. Configure OSPF.

Results

From configuration mode, confirm your configurationby entering the show firewall, and commit from configuration mode.

If you are done configuring Device R2, enter clear firewall all commandto reset the firewall counters to 0.

Sending TCP Traffic into the Network and Monitoring the Discards

Purpose

Make sure that the traffic of interest that is sentis rate-limited on the input interface (ge-2/0/5).

Action

1. Use a traffic generator to send 10 TCP packets with asource port of 80.

   The -s flag sets the source port. The -k flag causes the sourceport to remain steady at 80 instead of incrementing. The -c flag setsthe number of packets to 10. The -d flag sets the packet size.

   The destination IP address of 172.16.80.1 belongs to DeviceHost 2 that is connected to Device R2. The user on Device Host 2 hasrequested a webpage from Device Host 1 (the webserver emulated bythe traffic generator on Device Host 1). The packets that being rate-limitedare sent from Device Host 1 in response to the request from DeviceHost 2.

   Note

   In this example the policer numbers are reduced to a bandwidthlimit of 8 Kbps and a burst size limit of 1500 KBps to ensurethat some packets are dropped during this test.

   [root@host]# show firewall command.

Meaning

In Steps 1 and 2 the output from both devices showsthat 4 packets were discarded This means that there was at least 8 Kbpsof green (in-contract HTTP port 80) traffic and that the 1500 KBpsburst option for red out-of-contract HTTP port 80 traffic was exceeded.

Example: Configuring Interface and Firewall Filter Policersat the Same Interface

This example shows how to configure three single-ratetwo-color policers and apply the policers to the IPv4 input trafficat the same single-tag virtual LAN (VLAN) logical interface.

Requirements

No special configuration beyond device initialization is requiredbefore configuring this example.

Overview

In this example, you configure three single-rate two-color policersand apply the policers to the IPv4 input traffic at the same single-tagVLAN logical interface. Two policers are applied to the interfacethrough a firewall filter, and one policer is applied directly tothe interface.

You configure one policer, named p-icmp-500k-500k-discard to rate-limit traffic to 500 Kbps with a burst size of 500 Kbytes by discarding packets that do not conform to these limits.You configure one of the firewall filter terms to apply this policerto Internet Control Message Protocol (ICMP) packets.
