Just remember that there is 25% for the default class and routing
functions etc
Use the show interface before the policy is applied to see the available
BW for QoS - about halfway down - default is 75% only
I would increase this by putting the max-reserved 80 on the interface
Sounds more like this is a cosmetic issue since the logic is correct
Regarding your 3550 switch - I have a TAC case opened for a 3560G which
is not tagging packets at all or even matching on the default class - I
believe this is related to the software. Even a hardware analyser here
proves that the packets are not getting marked

Subject: Two QoS question
Hi Group,
I have two QoS question:
1) On a 2821 with IOS124-18 when I try to apply a policy-map out on the
Gigabit Ethernet Interface I always get the following errormessage, even
if
I reserve only a total of 75% (class high 35%, medium 30%, low 10%)
I/f GigabitEthernet0/1 class high requested bandwidth 35%, available
only 5%
It must somehow be box related, because on a 2611XM the same config
works
fine.
-->> Any Ideas?
2) On a C3550 following setup --R1--C3550--R2-- I configure a policer
for
the class default and apply it to a FE Port. Than I ping from R1 to R2,
which should match my class default. I never see matches on the class
default with sh policy-map interface.
Is it not possible to only use the class default? Here my config:
!
policy-map CCIEpolicy
class class-default
police 1000000 187500 exceed-action drop
!
int fa0/4
service-policy input vlan11policy
!
Thanks
Roger
