Introduction

This chapter provides examples for configuring traffic policing and aggregate CAR to control network traffic.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of traffic policing.

Example: Policing traffic by IP address and protocol type

Network configuration

As shown in Figure 1, a company uses a dedicated line to access the Internet, with an uplink bandwidth of 60 Mbps. All end devices use the firewall as the gateway. The mail server forwards emails for all clients to the external network. The FTP server provides data services for the branch through the Internet.

Configure traffic policing to classify and rate limit the uplink traffic as follows:

·          HTTP traffic—Rate limit HTTP traffic to a total rate of 40 Mbps (15 Mbps for the 25 hosts in the R&D department and 25 Mbps for the 40 hosts in the Marketing department).

·          Email traffic—Rate limit email traffic to 2 Mbps.

·          FTP traffic—Rate limit FTP traffic to 10 Mbps.

Figure 1 Network diagram

 

Analysis

To meet the network requirements, you must perform the following tasks:

·          Configure ACLs to classify packets of different types.

·          Associate classes with policing actions to rate limit packets of different types.

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware	Software version
S6800 switch series S6860 switch series S6861 switch series	Release 2702

 

Restrictions and guidelines

In a traffic behavior, the traffic policing action cannot be configured together with the following priority marking actions:

·          Local precedence marking.

·          Drop precedence marking.

·          802.1p priority marking.

·          DSCP marking.

·          IP precedence marking.

Otherwise, the class-behavior association for that traffic behavior cannot be applied correctly.

Example: Allocating bandwidth based on VLANs

Network configuration

As shown in Figure 2, the device aggregates traffic from the branches and transmits the traffic to the backbone network through a leased line. Each branch site assigns packets of different applications to different VLANs.

·          Configure one-to-one VLAN mapping on the following interfaces of the device to re-map traffic of different applications to VLANs as per the transmission scheme on the backbone network:

¡  Ten-GigabitEthernet 1/0/1.

¡  Ten-GigabitEthernet 1/0/2.

·          Configure traffic policing to allocate bandwidth to traffic from different VLANs, as shown in Table 1.

Table 1 Bandwidth allocation

XGE 1/0/1 and XGE 1/0/2 (uplink or downlink)			XGE 1/0/3 (uplink or downlink)			XGE 1/0/10 (uplink or downlink)
VLAN 1001	VLAN 1002	VLAN 1003	VLAN 201	VLAN 202	VLAN 203	VLAN 201	VLAN 202	VLAN 203
400 Mbps	200 Mbps	200 Mbps	400 Mbps	200 Mbps	200 Mbps	100 Mbps	60 Mbps	40 Mbps

 

Figure 2 Network diagram

 

Analysis

To meet the network requirements, you must perform the following tasks:

·          Configure VLAN-based traffic classes.

·          Configure per-VLAN traffic policing behaviors.

·          Associate each class with its specific traffic behavior.

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware	Software version
S6800 switch series S6860 switch series S6861 switch series	Release 2702

 

Restrictions and guidelines

In a traffic behavior, the traffic policing action cannot be configured together with the following priority marking actions:

·          Local precedence marking.

·          Drop precedence marking.

·          802.1p priority marking.

·          DSCP marking.

·          IP precedence marking.

Otherwise, the class-behavior association for that behavior cannot be applied correctly.

Procedures

Configuring VLAN settings

1.        Configure Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 as follows:

¡  Configure Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 as trunk ports.

¡  Assign them to VLANs 1001 through 1003 and VLANs 201 through 203.

¡  Remove them from VLAN 1.

¡  Configure one-to-one VLAN mappings on the two interfaces.

Example: Configuring aggregate CAR

Network configuration

As shown in Figure 5, the access layer devices add VLAN tags to the traffic from VLAN 10 and VLAN 100 before sending the traffic to the device.

Configure aggregate CAR on Ten-GigabitEthernet 1/0/1 to meet the following requirements:

·          Limit the incoming traffic from VLAN 10 and VLAN 100 to 200 Mbps.

·          Drop the excess traffic.

Procedures

# Configure interface Ten-GigabitEthernet 1/0/1 as a trunk port.

# Remove the interface from VLAN 1.

[Device-Ten-GigabitEthernet1/0/1] undo port trunk permit vlan 1

# Create an aggregate CAR action.

# Create behavior 1, and reference the aggregate CAR action in the behavior.

# Create behavior 2, and reference the aggregate CAR action in the behavior.

# Create a QoS policy named car, and associate the classes with the behaviors in the QoS policy.

Verifying the configuration

Verify the configuration on any interface, for example, Ten-GigabitEthernet 1/0/1.

# Verify QoS policies applied to interface Ten-GigabitEthernet 1/0/1.
