Your policy appears to be missing the FTP data, unless you also configured a
port map for that. 'ip nbar port-map ftp tcp 20 21'

In my opinion, anyone that doesn't know the default byte count for custom
queueing should not be attempting the lab.

The queue sizes need to be included to accurately reflect the traffic
ratios. Are you saying that if the FTP and the telnet queues had the
standard 1500 bytes, that you would just assign 'bandwidth remaining percent
100' to the www queue?

Depending on how picky the person grading the section was, they may also
want to see "queue-limit 20" for the other classes.

Hi guys,

Problem:
Convert the legacy custom queue config to MQC.

queue-list 1 protocol ip 1 tcp www
queue-list 1 protocol ip 2 tcp ftp
queue-list 1 protocol ip 2 tcp ftp-data
queue-list 1 protocol ip 3 tcp telnet
queue-list 1 default 4
queue-list 1 queue 1 byte-count 5000 limit 30
queue-list 1 queue 2 byte-count 3000
queue-list 1 queue 3 byte-count 500

My Solution was:

class-map match-all TELNET
  match protocol telnet
class-map match-all FTP
  match protocol ftp
class-map match-all WWW
  match protocol http
!
policy-map MQC
  class WWW
   bandwidth remaining percent 58
   queue-limit 30
  class FTP
   bandwidth remaining percent 35
  class TELNET
   bandwidth remaining percent 6

Question:

Is my solution which is different from that shown in the IE SG equally
correct?

I think my solution is better and simpler, assuming it's correct, because it
doesn't require

you to know that, by default, custom queueing reserves 1500 Bps for the
default queue and it doesn't require

you to change the max-reserved-bandwidth on the output interface.

What do you guys think?

Tim
