Hi,
We can classify them according to the IP addresses of the servers (once as source and once as destination), but in this case all the traffic from and to the servers will be treated the same way.

Hi,
What QoS parameters exactly that you require to configure, and what is the type of traffic in your network.
BR,
Mohammed Mahmoud.

Thanks, What i need is to configure QOS for the following:
- Client Server Application 1
- Client Server Applicaiton 2
- Internet Browsing
FYI, Our mail & proxy server are located at HO
many thanks in advance

Hi,
What is the connectivity technology between the routers (FR, MPLS, leased, ...), what is the bandwidth of each site, and what is the bandwidth that you wish to guarantee for each traffic type.
BR,
Mohammed Mahmoud.

Thanks,
Connectivity between routers is E1 leased line channel
HO to Branch A is 2 MB
HO to Branch B is 2 MB
HO to Branch C is 2 MB
HO to Branch D is 2 MB
HO to Branch E is 2 MB
this is for example:
Mail: 25%
Client Server Application 1 : 15%
Client Server Application 2 : 15%
Internet Browsing : 25%
Others : 20 %
Others meant undefined services.
many thanks in advance

Hi,
Here you are a basic QoS configuration.
For your knowledge the QoS doesn't interact unless there is congestion on the link.
First Define the classes (for mail use the protocols you require from the following, for app1 and app2 use an extended ACL to define them)
!
class-map match-any mail
match protocol pop3
match protocol smtp
match protocol imap
match protocol secure-pop3
match protocol secure-imap
match protocol exchange
match protocol ldap
class-map match-all http
match protocol http
class-map match-all app1
match access-group 101
class-map match-all app2
match access-group 102
Assign each traffic class the appropriate bw:
policy-map qos
class mail
bandwidth percent 25
class http
bandwidth percent 25
class app1
bandwidth percent 15
class app2
bandwidth percent 15
class class-default
fair-queue
You then need to classifiy app1 and app2 traffic may be according to the port number used:
access-list 101 permit tcp any any eq
access-list 101 permit tcp any eq
access-list 102 permit tcp any any eq
access-list 102 permit tcp any eq
Apply the policy under each interface in the output direction:
interface serial 0/0
bandwidth 2048
service-policy output qos
I hope that i've been informative.

Hi..
You wrote:

did you mean that if there is no congestion on the link then the first come class will get full bw regardless the QOS ? pls advise
thanks & regards

Hi Winanjaya
Whatever Mohammed told you is a congestion management which is one of many methods of QOS implementation. If your link isn't congestion(Hardware Queue full) then software queuing that you configured won't be used at all.

Hi Winanjaya,
Yes what i meant is that the congestion management tools that we've configured till now will only interact when there is congestion, which is fair, in the case that there is no congestion any traffic of them can talk more than what was guaranteed for him which is nice, but in the moment of congestion the values we configured are met, which is what we are looking for.
HTH, please rate if it does help,

How about for App1, App2 they don't have static service port
