Hi,
I do not see any difference. Maybe I am color blind :-)
Cheers,

Hi GS !
Please explain what is the deference btw 2 ways of QoS Configuration :
Method 1:
class-map match-all PRE2
match ip precedence 2
class-map match-all PRE3
match ip precedence 3
!
policy-map PARENT
class PRE2
shape average 512000
service-policy CHILD-PRE2
class PRE3
shape average 1024000
service-policy CHILD-PRE3
!
policy-map CHILD-PRE2
class class-default
bandwidth 256
policy-map CHILD-PRE3
class class-default
bandwidth 512
!
interface serial 1/0
service-policy output PARENT
Method 2:
class-map match-all PRE2
match ip precedence 2
class-map match-all PRE3
match ip precedence 3
!
policy-map PARENT
class PRE2
shape average 512000
bandwidth 256
class PRE3
shape average 1024000
bandwidth 512
!
interface serial 1/0
service-policy output PARENT
In my understand, Interface will allocate bandwidth of 256kbps for Class PRE2
& 512kbpp for Class PRE3 when congestion occur in Method 1. However, In
Method
2, I don't understand how Interface process queue.
Correct me if I am wrong !
Thanks
