Folks,
I found this example about QoS in Cisco course manual but I didn't get
some points , let's start watching:
Enable CQ between two routers R1 and R2 according to the following
policy:
- classify telnet traffic into a pre-emptive queue (what soes it
means?!!!??)
- classify ICMP traffic so that it gets at least 10% of the BW
- classify FTP traffic so that it gets at least 50% of the BW
- classify the rest of the traffic so that it gets the rest of the BW.
The solution
Access-list 101,,,defines Telnet
Access-list 102 ,,defines FTP
Access-list 103 permit icmp any any
Queue-list 1 protocol ip 1 list 101
Queue-list 1 protocol ip 2 list 102
Queue-list 1 protocol ip 3 list 103
Queue-list 1 default 4
Queue-list 1 queue 2 byte-count 5000
Queue-list 1 queue 3 byte-count 1000
Queue-list 1 queue 4 byte-count 4000
Queue-list 1 lowest-custom 2
Interface serial 0
Custome-queue-list 1
The questions
1- from where he calculated this byte-count although he didn't define
the bandwidth on the interface except the the percentage already
stated ? may be I'm misunderstand something
2- what is the benefit behind the command lowest-custom
3- what does he mean from the keword pre-emptive queue
thanxxx
