hello Toonsh,
 
My recomendtion would be first marking ICMP traffic with the COS value then use cos-to-DSCP map

Hi,

I have just run some tests trying to set ingress traffic on a 3550 L2 port
to a DSCP value of 45.

mls qos
!
class-map match-all ICMP
match access-group 101
!
!
policy-map TEST
class ICMP
set dscp 45
!
access-list 101 permit icmp any any
!
int f0/1
service-policy input TEST

If I run a trace on the receiving end I see the DSCP value has remained
unchanged. Am I missing something ? What are some other ways of setting
ingress traffic PREC or DSCP values.

Thanks
