简介
本文档介绍如何在Cisco Catalyst 6800ia主机端口上配置、验证服务质量(QoS)并对其进行故障排除。Catalyst 6800父虚拟交换系统(VSS)上Cisco IOS®软件版本152.1.SY及更高版本的6800ia主机端口支持QoS。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档中的信息基于以下软件和硬件版本：
- Cisco IOS®软件版本152.1.SY
- Cisco Catalyst 6800父VSS
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。
背景信息
Catalyst 6800ia的配置模式已禁用，所有6800ia主机端口的QoS配置必须从父端完成。6800ia主机端口的QoS配置了策略映射。应用到接口时，此策略映射将相关配置内部推送到6800ia，然后对硬件队列进行编程。
6800ia主机端口在传输(TX)方向具有1p3q3t架构。本文档中的所有配置示例仅适用于6800ia上的TX队列。
当6800ia接口上没有默认状态的显式QoS配置时，6800ia主机接口的输出可能与以下示例输出类似：
6880-VSS#show run int gi101/1/0/1
interface GigabitEthernet101/1/0/1
switchport
switchport trunk allowed vlan 500
switchport mode access
switchport access vlan 500
load-interval 30
end

配置
配置示例1:队列带宽
此示例显示如何为6800ia TX队列配置带宽：
- 配置类映射以对所关注的流量进行分类：
class-map type lan-queuing match-any ltest
match dscp 32
class-map type lan-queuing match-any ltest1
match dscp 24
class-map type lan-queuing match-any ltest2
match dscp default - 为已配置的类分配优先级和带宽：
policy-map type lan-queuing ltest
class type lan-queuing ltest
priority
class type lan-queuing ltest1
bandwidth remaining percent 30
class type lan-queuing ltest2
bandwidth remaining percent 20
class class-default - 将策略映射应用到有问题的6800ia接口：
注意：当您将lan排队策略映射应用到6800ia堆叠上的一个端口时，它会将更改传播到堆叠中的所有端口。

注意：如果不指定某个类的缓冲区权重，则默认为100%。
队列 1:15 / [15+100+100+100] = 4
队列 2:100 / [15+100+100+100] ~ 31
对于其他队列，也会得出权重。
