Enterasys Networks X-PeditionTM manual QoS with Mlppp Multi-Class Policy

QoS Policy Configuration Examples

Create a policy map consisting of one or more traffic classes and specify QoS characteristics for each traffic class:

XSR(config)#policy-map frame1 XSR(config-pmap<frame1>)#class voice XSR(config-pmap-c<voice>)#priority high 20 2500 XSR(config-pmap-c<voice>)#queue-limit 32 XSR(config-pmap-c<voice>)#set ip dscp 46 XSR(config-pmap-c<voice>)#exit XSR(config-pmap<frame1>)#class ftp XSR(config-pmap-c<ftp>)#bandwidth percent 50

XSR(config-pmap-c<ftp>)#police 30000 3000 6000 conform-action set-dscp-transmit 10 exceed-action set-dscp-transmit 12 violate-action set-dscp-transmit 14 XSR(config-pmap-c<ftp>)#random-detect 20 35 250 XSR(config-pmap-c<ftp>)#exit

Configure map class parameters and apply the policy to the ports:

XSR(config)#map-class frame-relay cc

XSR(config-map-class<cc>)#frame-relay cir 64000

XSR(config-map-class<cc>)#frame-relay adaptive-shaping becn

XSR(config-map-class<cc>)#frame-relay bc 8000

XSR(config-map-class<cc>)#frame-relay be 16000

XSR(config-map-class<cc>)#service-policy out frame1

XSR(config-map-class<cc>)#exit

XSR(config)#interface serial 1/1

XSR(config-if<S1/1>)#encapsulation frame-relay

XSR(config<S1/1>)#frame-relay traffic-shaping

XSR(config<S1/1>)#no shutdown

XSR(config<S1/1>)#exit

XSR(config)#interface serial 1/1.1 point-to-point

XSR(config-subif<S1/1.1>)#frame-relay interface-dlci 100

XSR(config-fr-dlci<S1/1.1-100>)#frame-relay class cc

XSR(config-fr-dlci<S1/1.1-100>)#ip address 10.10.10.2 255.255.255.0

XSR(config-fr-dlci<S1/1.1-100>)#no shutdown

QoS with MLPPP Multi-Class Policy

In the following example, configure fragment delay to 10 milliseconds, classify RTP traffic as latency sensitive, match FTP traffic by FTP class, and allocate 30 percent of the output bandwidth. All other traffic is matched as default class. Also, fragment and interleave FTP packets and default-class packets with VoIP-RTP packets.

XSR(config)#class-map VoIP-RTP

XSR(config-cmap<VoIP-RTP>)#match access-group 101

XSR(config-cmap<VoIP-RTP>)#exit

XSR(config)#class-map FTP

XSR(config-cmap<FTP>)#match access-group 102

XSR(config-cmap<FTP>#exit

XSR(config)#policy-map QoS-Policy
