Hi all,

I would use "police" but that is my opinion. You can play with the
numbers. If you use WRED that has a drop ratio you can choose but I would
prefer policing.

See example below and it is open for comment.

e.g

 class-map match-all data
  match access-group 102
 class-map match-all voice
  match access-group 101
!
!
 policy-map my_policy
  class voice
   priority 24
  class data
   bandwidth percent 40
  class class-default
   police cir 16000 bc 2000
     conform-action transmit
     exceed-action drop
     violate-action drop
!
access-list 101 permit udp any any range 16384 32767
access-list 101 permit tcp any any eq 1720
access-list 102 permit tcp any any eq telnet
access-list 102 permit tcp any any eq ftp-data
access-list 102 permit tcp any any eq ftp
access-list 102 permit tcp any any eq tacacs
!
interface serial 0/0
service-policy output my_policy

Kind regards

James
