Hi Edward,
If you are using cbqos you can "show policy-map int x <direction>" and see what
actions have occurred there
E.g.
On R1 egress have a look at the counters of show policy-map int s1/1 output
Marked to see whats happening
On R2 ingress have a look at the number of packets against each class
R1
class-map match-all MatchS1/1
match access-group 100
policy-map Egress
class MatchS1/1
set ip precedence 5
class class-default
set ip precedence 0
interface Serial1/1
ip address 1.1.1.1 255.255.255.0
encapsulation ppp
load-interval 30
clock rate 64000
service-policy output Egress
!
access-list 100 permit ip host 1.1.1.1 any
R2
class-map match-all IPPrec0
match ip precedence 0
class-map match-all IPPrec1
match ip precedence 1
class-map match-all IPPrec2
match ip precedence 2
class-map match-all IPPrec3
match ip precedence 3
class-map match-all IPPrec4
match ip precedence 4
class-map match-all IPPrec5
match ip precedence 5
class-map match-all IPPrec6
match ip precedence 6
class-map match-all IPPrec7
match ip precedence 7
