cisco 9200 qos 配置

以下是 Cisco 9200 上的 QoS 配置示例：

1. 配置 class map

class-map match-any VOICE
 match protocol sip
 match protocol rtp audio

class-map match-any VIDEO
 match protocol rtcp
 match protocol rtp video

class-map match-any BULK-DATA
 match protocol bit-torrent

class-map match-any INTERACTIVE
 match protocol icmp
 match protocol dns
 match protocol http
 match protocol ssh
 match protocol telnet
 match protocol snmp

2. 配置 policy-map

policy-map OUTBOUND-QOS
 class VOICE
  priority percent 50
 class VIDEO
  bandwidth percent 20
 class INTERACTIVE
  bandwidth percent 10
 class BULK-DATA
  bandwidth percent 5
 class class-default
  bandwidth percent 15

3. 将 policy-map 应用于接口

interface GigabitEthernet1/0/1
 service-policy output OUTBOUND-QOS

这些命令将配置 QoS，使语音流量具有最高优先级，视频流量具有次高优先级，交互性流量具有较高优先级，大数据流量具有较低优先级，并为默认流量分配适当的带宽。
