[Click] DSCP markup question

[Victor]

Hello,

I am trying to implement DiffServ router using Click.

One question I couldn't figure out so far: how to use the framework to
markup packets?

So far I used 'iptables', for example: iptables -t mangle -A PREROUTING -i
eth0 -t mangle -p UDP -destination-port PORT_NUM -j DSCP -set-dscp 0x2e

How can I implement that in "Click" to the same effect?

Is there diffserv configuration examples provided with 1.7.0rc1
distribution?

 

Thank you,

-vl
