Hello All

A quick QOS question on my config. I have the following config i would like to apply to my interface. My question is will my first ACL:

ip access-list extended GOLD-QOS-ACL
permit ip any any


Class all of the other traffic in my:

policy-map UK-WAN-QOS-Out

as IP any any or will the other ACL's come into effect on the relevant classes aswell?

I guess what im asking is will allowing IP ANY ANY in my first ACL, include all the traffic that i am trying to control after it? In effect making the other ACL entries redundant.

HERE IS THE CONFIG:


time-range Business_Hours
periodic weekdays 9:00 to 17:30
!
ip access-list extended GOLD-QOS-ACL
permit ip any any
!
ip access-list extended ALTIRIS-QOS-ACL
permit ip host 172.20.*.* any time-range Business_Hours
permit ip host 172.20.*.* any time-range Business_Hours
!
ip access-list extended DOUBLETAKE-QOS-ACL
permit ip host 172.20.*.* any time-range Business_Hours
!
ip access-list extended NETBOTZ-QOS-ACL
permit ip 172.20.*.0 0.0.0.255 any time-range Business_Hours
!
class-map match-any GOLD-DATA
match access-group name GOLD-QOS-ACL
!
class-map match-any ALTIRIS-DATA
match access-group name ALTIRIS-QOS-ACL
!
class-map match-any DOUBLETAKE-DATA
match access-group name DOUBLETAKE-QOS-ACL
!
class-map match-any NETBOTZ-DATA
match access-group name NETBOTZ-QOS-ACL
!
policy-map UK-WAN-QOS-Out
class GOLD-DATA
bandwidth percent 60
class ALTIRIS-DATA
bandwidth percent 5
class DOUBLETAKE-DATA
bandwidth percent 5
class NETBOTZ-DATA
bandwidth percent 5
class class-default
fair-queue

!

Hope someone can help

Regards

Rob
 
Basically the router will look at each class in turn defined in the policy map. The first match it sees for a particular packet will mean that packet will receive the associated level of service.

I see from your config that your first class (GOLD-DATA) calls on the permit ip any any ACL therefore ALL traffic will be serviced by this class and the others won't be looked at (for IP traffic anyway).

If this is undesired, you need to rejig your policy map and place in the classes in the order you want them serviced. You usually place the more-specific classes first and the general and/or catch-all classes last.
