Hi forum,
I am working on a QoS project. I want to mark some kinds of traffic generated by router itself such as ICMP, syslog, Netflow and SNMP . I intend to mark them as Management Services and as DSCP af32 then put af32 and af31, which I already marked by HTTP services on a Queue. The problem is that when I mark Management Service in an Output Policy-map, the HTTP service also remarked as af32 too. I don't know how to mark those Management services without remark HTTP service, then put 2 markers in same output queue???
I have some commands here to help you understand my problem.
class-map HTTP
match protocol http
class-map Ouput_queue
match dscp af31
match protocol icmp
match protocol syslog
match protocol snmp
!
Policy-map Mark_http
class HTTP
set dscp af31
!
Policy-map output_Queue
class Ouput_queue
set dscp af32 ---> Also remark HTTP traffic
bandwidth 256
Plz help me

Hi,
Maybe this could work:
class-map Ouput_queue
match not class-map HTTP
match dscp af31
match protocol icmp
match protocol syslog
match protocol snmp
This way HTTP which has dscp AF31 won't be set DSCP 32 but it will be classified as class-default traffic, is this what you wish?
Regards.

Thanks to cadet alain,
But that 's not what I want. Maybe I should forget this trouble. I must weigh whether marking or queueing those traffics. And in my situation, I think Marking is more important. When marked, the rest of routers will give them a right queue later. Only in one section of network, traffics generated by a router classified in class-default, however those in the other sections will be classified in right class. Therefore, the purpose of QoS is still acceptable.
Here is my policy-map in Routers
LAN1------(RouterA)-------(RouterB)-------(RouterC)----LAN2
class match-any MANAGEMENT_SERVICE
match protocol icmp
match protocol syslog
match protocol snmp
class-map match-any BUSINESS_TRAFFIC
match ip dscp af31
match ip dscp af32
policy-map OUTPUT_POLICY
class BUSINESS_TRAFFIC
bandwidth 1024
random-detect dscp-based
class MANAGEMENT_SERVICE
set dscp af32
