Raj,
Custom Queing allows for up to 16 ques, with 0 reserved for the system.
As far as your question and looking at byte-count, it used to be that
packet size needed to be taken into account to determine the percentage
of bandwidth on older IOS versions (ala before 12.2T which is all I care
about as a CCIE R&S lab student).
Anyhow, you can just set the byte-count values such that the weighted
average yields the percentages in the question. Do NOT forget to take
into account the default que byte-count though. Otherwise the weighted
average will be incorrect as configured.
Example:
queue-list 10 protocol ip 1 list 100
queue-list 10 protocol ip 2 list 101
queue-list 10 default 3
queue-list 10 queue 1 byte-count 4000
queue-list 10 queue 2 byte-count 2000
queue-list 10 queue 3 byte-count 4000
Access-list 100 permit tcp any eq www any
Access-list 100 permit tcp any any eq www
Access-list 100 permit tcp any eq 443 any
Access-list 100 permit tcp any any eq 443
Access-list 101 permit tcp any eq ftp any
Access-list 101 permit tcp any any eq ftp
Access-list 101 permit tcp any eq ftp-data any
Access-list 101 permit tcp any any eq ftp-data
Note the total byte-count for the ques is 10000 (4000+2000+4000). This
way each que receives a percentage requested based on the weighted
average (e.g. que1=40%, que2=20$, que3=40%).
If you did not specify the default que, it defaults to 1500. This would
have yielded a total size of 7500. And your percentages would be 53%,
27%, 20% for ques 1, 2, and 3 respectively.
HTH,
Andy

Subject: custom queue
Hi Group,
Trying to understand custom queue
If I want to configure a queuing on a serail interface which has got
256kbps bandwidth. Now. I want ftp to use 20% www 40% and rest for
normal ip traffic. I am not very clear how this byte-count works.
Could any one please help.
Thansn advance
Raj
