You can create bandwidth control policy and apply to VS.

what about if I want to marking an application? for example www.example.com af21?
Thx again.
- volodh_214395NimbostratusYou can create tcp profile and specify there IP ToS or Link QOS setting. Than set this profile to your virtual server -Protocol Profile (Client) and / or Protocol Profile (Server) options. IP ToS is used for layer 3 marking. Link QOS is used for layer 2 marking. Since you want to mark using DSCP you need to use IP ToS = 72. Which is equivalent of dscp af21.

This can be configured under Acceleration ›› Bandwidth Controllers ›› myBWC >> Dynamic Properties(Enable) >> IP Marking (DSCP & ECN)(Specify)
- KJ_50941NimbostratusThx, so created "myBWC" in IP Marking (DSCP & ECN) change to AF21, and apply "myBWC to virtual server. is that all I need or do I need to use iRule as well. when CLIENT_ACCEPTED { if { [IP::tos] == 72 } { pool example_80

The irule mentioned is to select the pool based on incoming packet DSCP. What is the requirement on QoS?
- KJ_50941NimbostratusMarking specific applications for af21, and another for af41 and af43. how do I do That. Thank you in advanced.

Try using iRule;
To set QoS af41 towards the client
when CLIENT_ACCEPTED { IP::tos 72 }
To set QoS af41 towards the server
when SERVER_CONNECTED { IP::tos 72 }
- KJ_50941Nimbostratus
do I need to modify pool ? or irule alone will set the marking for Af21?
IP ToS to Client IP ToS to Server
- kunjanNimbostratus
No need to modify the pool if irule used, which gives the flexibility to apply qos based on traffic coming in.
