Both WWW & SMTP will get 35% each in Config 1 whereas in Config2 WWW & SMTP
will get 35% combined.
So, the First config is correct as per my opinion ..in both cases you would
need to specify bandwidth under the interface as by default it will assume
it to be 1544 Kbps.
Hope it helps.

Hi group,
Here is a question about CBWFQ.During congestion ,I want
to reserve atleast 35 % for www" & 35 % for "smtp" traffic.I can find two
solutions,but want to fix it on one.Which of these configurations is more
correct ?
Configuration 1
----------------
!
access-list 101 permit tcp any
any eq www
!
access-list 102 permit tcp any any eq smtp
!
class-map WWW
match
access-group 101
!
class-map SMTP
match access-group 102
!
policy-map QoS
class WWW
bandwidth percent 35
class SMTP
bandwidth percent 35
!
int s
0/0
service-policy output QoS
!
Configuration 2
---------------
!
access-list 101 permit tcp any any eq www
access-list 101 permit tcp any any
eq smtp
!
class-map WWW-SMTP
match access-group 101
!
policy-map QoS
class
WWW-SMTP
bandwidth percent 35
!
int s 0/0
service-policy output QoS
!
Regarding the second configuration,I have doubt whether 35% is reserved
combined for www & smtp ?
---------------------
And my next question is
since I am not specifically configuring any bandwidth value(only bandwidth
percentage),need I configure the bandwidth command under s0/0 ?
Thanks,
Peter
