MQC----MQC(Modular QoS Command-Line)。

MQC就是模块化QOS命令行,是配置QOS处理数据的一种非常合乎逻辑的方式。MQC可以配置对特定的数据采取特定的动作,步骤为三步: 定义流量 设置策略 应用策略

实验目标:演示基本的MQC操作。

步骤1、全网可达,即用IGP使得各个网段以及环回口可达,不再赘述

R3#sh ip route

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default, U - per-user static route

o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

33.0.0.0/24 is subnetted, 1 subnets

C 33.1.1.0 is directly connected, Loopback0

23.0.0.0/24 is subnetted, 1 subnets

C 23.1.1.0 is directly connected, Serial1/0

22.0.0.0/24 is subnetted, 1 subnets D 22.1.1.0 [90/2297856] via 23.1.1.2, 00:10:30, Serial1/0 11.0.0.0/24 is subnetted, 1 subnets

D 11.1.1.0 [90/2300416] via 23.1.1.2, 00:10:28, Serial1/0

12.0.0.0/24 is subnetted, 1 subnets

D 12.1.1.0 [90/2172416] via 23.1.1.2, 00:10:30, Serial1/0

R3#ping 11.1.1.1 source lo0

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 11.1.1.1, timeout is 2 seconds:

Packet sent with a source address of 33.1.1.1

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 8/26/60 ms

步骤2、在R2上配置MQC,及定义流量,设置策略,应用策略

用ACL来定义从11.1.1.1到33.1.1.1的IP优先级为4的流量

R2#access-list 100 permit ip host 11.1.1.1 host 33.1.1.1 precedence

flash-override

利用class-map和policy-map来设置策略

class-map match-all Silver

match access-group 100

!

!

policy-map SET-TAG

class Silver

set ip precedence 5

最后在接口下调用

interface Serial2/0

ip address 23.1.1.2 255.255.255.0

serial restart-delay 0

service-policy output SET-TAG

验证:

R1#ping

Protocol [ip]:

Target IP address: 33.1.1.1 Repeat count [5]: 20

Datagram size [100]:

Timeout in seconds [2]:

Extended commands [n]: y

Source address or interface: 11.1.1.1

Type of service [0]: 128

Set DF bit in IP header? [no]:

Validate reply data? [no]:

Data pattern [0xABCD]:

Loose, Strict, Record, Timestamp, Verbose[none]:

Sweep range of sizes [n]:

Type escape sequence to abort.

Sending 20, 100-byte ICMP Echos to 33.1.1.1, timeout is 2 seconds:

Packet sent with a source address of 11.1.1.1

!!!!!!!!!!!!!!!!!!!!

Success rate is 100 percent (20/20), round-trip min/avg/max = 4/13/64 ms

R2上查看包的匹配情况

R2#sh policy-map interface

Serial2/0

Service-policy output: SET-TAG

Class-map: Silver (match-all)

20 packets, 2080 bytes

5 minute offered rate 0 bps, drop rate 0 bps

Match: access-group 100

QoS Set

precedence 5

Packets marked 20

Class-map: class-default (match-any)

438 packets, 28755 bytes

5 minute offered rate 0 bps, drop rate 0 bps Match: any

R2#sh access-l

Extended IP access list 100

10 permit ip host 11.1.1.1 host 33.1.1.1 precedence flash-override (20

matches)

此例为基本的简单实验,希望大家能够初步的认识MQC
