Hi Brian and all,
 
The question gives set of custom queueing and asks us to conver to MQC.
=================================================
int e 0/1
  custom-queue-list 1
 
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[we are taking byte count for queue 4/default as 1500]
 
queue-list 1 protocol ip 1 tcp www
queue-list 2 protocol ip 2 tcp ftp
queue-list 2 protocol ip 2 tcp ftp-data
queue-list 3 protocol ip 3 tcp telnet
queue-list 4 default
=================================================
Solution in the guide:
ip cef
class-map TELNET
  match protocol telnet
class-map FTP
 match protocol FTP
class-map match-all WWW
 match protocol HTTP
 
policy-map MIGRATION
  class WWW
    bandwidth percent 50
    queue-limit 30
  class FTP
    bandwidth percent 30
  class TELNET
    bandwidth percent 5
 
interface eth 0/1
   max-reserve-bandwidth 85
   service-policy output MIGRATION
==========================
NOW for the question, the answer given in the solution guide is right because it changed the max reserve bandwidth to 85 and class-default takes remaining 15 percent bandwidht.
But What is the implication of defining bandwidth percent for class default
 
eg:
class class-default<---I know this accomplishes the same thing but is there is any difference
   bandwidth percent 15
 
If we define a bandwidth percent for class class-default, do we have to leave the max-reserve bandwidth as 85 or changed to max-reserve-bandwidth 100. Any help is appreciated.
 
thanks
