1  通过重标记QoS本地标识符实现分层QoS典型配置举例

1.1  简介

重标记qos-local-id功能主要用于将匹配多种分类条件的报文进行重分类，再为这个重分类配置流行为的情况。本章为您介绍使用重标记QoS本地标识符功能实现分层QoS的配置举例

1.2  通过重标记QoS本地标识符实现分层QoS典型配置举例

1.2.1  适用产品和版本

表1 配置适用的产品与软硬件版本关系

1.2.2  组网需求

某公司内网的结构如图1所示，现要求使用流量监管和重标记QoS本地标识符功能，对各部门访问外网的流量进行限速。其中对管理部和研发部分别限速1024Kbps，市场部（包含两个子部门）的总流量限速为2048Kbps。

图1 通过QoS本地标识符实现分层QoS组网示意图

1.2.3  配置注意事项

流分类和流行为的配对的生效顺序与配置顺序保持一致，因此在配置QoS策略时，需要首先配置重标记QoS本地标识符的配对，然后再配置对该QoS本地标识符的流量进行其他动作的配对。

1.2.4  配置步骤

1. 对管理部和研发部上行流量的限制

# 创建基本IPv4 ACL 2001，匹配管理部发送的流量。

<SwitchA> system-view

[SwitchA] acl number 2001

[SwitchA-acl-basic-2001] rule permit source 192.168.1.0 0.0.0.255

[SwitchA-acl-basic-2001] quit

# 创建基本IPv4 ACL 2002，匹配研发部发送的流量。

[SwitchA] acl number 2002

[SwitchA-acl-basic-2002] rule permit source 192.168.2.0 0.0.0.255

[SwitchA-acl-basic-2002] quit

# 创建流分类admin，匹配管理部发送的流量（即匹配ACL 2001）。

[SwitchA] traffic classifier admin

[SwitchA-classifier-admin] if-match acl 2001

[SwitchA-classifier-admin] quit

# 创建流分类rd，匹配研发部发送的流量（即匹配ACL 2002）。

[SwitchA] traffic classifier rd

[SwitchA-classifier-rd] if-match acl 2002

[SwitchA-classifier-rd] quit

# 创建流行为car_admin_rd，动作为流量监管，限速值为1024Kbps。

[SwitchA] traffic behavior car_admin_rd

[SwitchA-behavior-car_admin_rd] car cir 1024

[SwitchA-behavior-car_admin_rd] quit

# 创建QoS策略car，将流分类admin和rd分别与流行为car_admin_rd进行配对。

[SwitchA] qos policy car

[SwitchA-qospolicy-car] classifier admin behavior car_admin_rd

[SwitchA-qospolicy-car] classifier rd behavior car_admin_rd

[SwitchA-qospolicy-car] quit

2. 对市场部上行流量的限制

# 创建基本IPv4 ACL 2003，匹配市场一部发送的流量。

[SwitchA] acl number 2003

[SwitchA-acl-basic-2003] rule permit source 192.168.3.0 0.0.0.255

[SwitchA-acl-basic-2003] quit

# 创建基本IPv4 ACL 2004，匹配市场二部发送的流量。

[SwitchA] acl number 2004

[SwitchA-acl-basic-2004] rule permit source 192.168.4.0 0.0.0.255

[SwitchA-acl-basic-2004] quit

# 创建流分类marketing，匹配条件为市场一部或市场二部的流量。

[SwitchA] traffic classifier marketing operator or

[SwitchA-classifier-marketing] if-match acl 2003

[SwitchA-classifier-marketing] if-match acl 2004

[SwitchA-classifier-marketing] quit

# 创建流行为remark_local_id，动作为重标记QoS本地标识符为100。

[SwitchA] traffic behavior remark_local_id

[SwitchA-behavior-remark_local_id] remark qos-local-id 100

[SwitchA-behavior-remark_local_id] quit

# 创建流分类marketing_car，匹配条件为市场一部或市场二部的流量。

[SwitchA] traffic classifier marketing_car

[SwitchA-classifier-marketing_car] if-match qos-local-id 100

[SwitchA-classifier-marketing_car] quit

# 创建流行为marketing_car，动作为流量监管，限速值为2048Kbps。

[SwitchA] traffic behavior marketing_car

[SwitchA-behavior-marketing_car] car cir 2048

[SwitchA-behavior-marketing_car] quit

# 在QoS策略car中，将流分类marketing和流行为remark_local_id进行配对，即使用QoS本地标识符100来标记市场部的流量。

[SwitchA] qos policy car

[SwitchA-qospolicy-car] classifier marketing behavior remark_local_id

# 然后将流分类marketing_car和流行为marketing_car进行配对，即对QoS本地标识符为100的流量进行限速。

[SwitchA-qospolicy-car] classifier marketing_car behavior marketing_car

[SwitchA-qospolicy-car] quit

# 将QoS策略car应用在端口Ten-GigabitEthernet1/0/1的入方向上，完成流量监管配置。

[SwitchA] interface Ten-GigabitEthernet 1/0/1

[SwitchA-Ten-GigabitEthernet1/0/1] qos apply policy car inbound

1.2.5  验证配置

# 查看端口Ten-GigabitEthernet1/0/1上应用的QoS策略。
