Jim
Thanks for that, I have just looked this up in the Cisco Press QOS book, in
this book it specifies that when using CBWFQ the bandwidth command is there
to specify the Min bandwidth traffic (In this case ACL X) can use per class.
My question was no more than 50% (MAX), I think your example may well be
correct and the book be incorrect.
Does anyone have any feedback on this, when specifying bandwidth for an ACL
via a service policy and class map does the bandwidth statement apply Max
Bandwidth allowed or Min Bandwidth allowed ?
Thanks
Steve

Steven,
Do you have to do this with custom queueing? If not look into CBWFQ. You can
define the traffic with your acl in the map class, then assign that
map-class to a policy map and under the class there you can define the
bandwidth by percent.
Not sure if this fits your needs or not.

class-map match-all percent
match access-group 166
!
!
policy-map percent
class percent
bandwidth percent 50
!
access-list 166 permit tcp any any eq 2065
access-list 166 permit tcp any eq 2065 any
access-list 166 permit tcp any any eq 2067
access-list 166 permit tcp any any eq 1981
access-list 166 permit tcp any any eq 1982
access-list 166 permit tcp any any eq 1983

I have a scenario to allow no more than 50% of the bandwidth on an ethernet
interface, I know about the port numbers and the priority (1981 etc etc) but
I am not given any packet sizes to work with.
I am assuming that the default packet size is the standard 1500 bytes, if so
does this config look OK for 50% of the bandwidth on E0
interface Ethernet0
backup interface BRI0
