Raj,
With MQC, you use the class-map construct to define what traffic you want to
affect. Depending on what you want to accomplish, you can affect either
incoming or outgoing traffic.
As you probably realize, an acl can be used to identify a very large range
of different types of traffic. What's key to remember if that you use the
permit keyword to SELECT the traffic you want to affect in your policy map.
A deny in your acl means don't act upon this traffic.
Now, with respect to specifying port on the source or destination that also
depends. Typically, with TCP and UDP, the well known port is used on
traffic going to or coming from the server.
For example, suppose you have a SMTP or HTTP or DNS server hanging off of
R1's E0 interface.
If you want to affect traffic GOING TO the server, you'd put the eq XXX
after the destination address. If you want to affect traffic COMING FROM
the server, you'd put the eq XXX after the source address.
HTH, Tim

Subject: access-list with class-map
Hi Gorup,
I am bit confused how access-list should be used under class-map. Not sure
where to use eq protcol under source or destination field.
Does this depend on whether service-policy applied inboud or outbound
Your help will be highly apprecited.
Thanks in advance
Raj
