I understand this question need to configure custom queuing because it
require to allocate bandwidth by percentage. If you are using bit/second,
you will need to have traffic-shape configuration on the interface.
r1(config-if)#traffic-shape ?
group configure token bucket: group <access-list> CIR (bps) [Bc (bits)
[Be
(bits)]]
rate configure token bucket: CIR (bps) [Bc (bits) [Be (bits)]]
which group number will be access-list you configured for diferent protocol.
Custom queuing is expalined below.
first , telnet will take 20 %, IPX will take 10 %, 40 % for IP and default
will be 30 % (20+10+40+30=100%)
since default will be 1500 byte, so 10 % will be 1/3 of 1500=500 byte.
next things are easy based on 10 % of bandwidth.
1 telnet 2 * 10 % => 1000 byte
2 IPX 1 * 10 % => 500 byte
3 IP 4 * 10 % => 2000 byte
4 default 1500 byte.
!configuration should be
queue-list 1 protocol ip 1 tcp telnet
queue-list 1 protocol ipx 2
queue-list 1 protocol ip 3
queue-list 1 default 4
queue-list 1 queue 1 byte-count 1000
queue-list 1 queue 2 byte-count 500
queue-list 1 queue 3 byte-count 2000
! from show run
! even though you type in byte count for default que, it will not show up on
tour config
queue-list 1 que 4 byte-count 1500
.
Hope this one help you.
check link below, it has very good explanation with sample config for
diferent trafic shaping
