Hi Brian,
I'm not sure i understand your logic.
If i make 2 class, one for fpt and the other for tcp and Ftp class goes
first:
access-group 101 permit tcp any any
!
class ftp
match protocol ftp
class tcp
match access-group 101
!
policy-map QoS
class ftp
police cir 2000000
class tcp
police cir 5000000
!
In this case, every packet that match ftp class will NOT be matched again in
TCP class.
The problem is that, if there are 2M ftp traffic already match in fpt class,
then the total bandwidth for tcp traffic may be 7M (2M FTp + 5M TCP <not FTP
traffic>).
This violate the 5M TCP trafffic requirement in question.
In my solution, ftp class will be nested in tcp class:
!
policy-map ftp
class ftp
police cir 2000000
!
policy-map QoS
class tcp
police cir 5000000
service-policy ftp
!
What will you recommend in my solution ?
Thanks
B.L
