QOS Class Based Weighted Fair Queuing

Class Based Weighted Fair Queuing





Http Should get bandwidth 20 and queue limit should be 10 packets

Telnet should get bw 80 and queue limit should be 20 packets


By default we can reserve 75% of the interface bandwidth for QOS, if you will try to reserve more than that you will get the below error



to allocate the bandwidth more than 75% you need to configure max-reserved-bandwidth 100 on the interface.

R2 Config:
ip access-list extended http
 permit tcp any any eq www
ip access-list extended telnet
 permit tcp any any eq telnet
!
class-map match-all TELNET
 match access-group name telnet
class-map match-all HTTP
 match access-group name http

Now try to telnet R4 from R1 and see the packets are matching the Telnet Class and same in the case when we are accessing R4 over the port 80(http)
