Hi, I'm trying to configure QoS on a frame relay link, and am running short of time (carrier took 8 weeks to provision!).. Can anyone please give me a run down of the easiest way to configure QoS on a 2851 and 3640 (both running IOS 12.4.10) on the frame relay port so that we can classify traffic by src and/or dest IP address, TCP ports or protocol. I have to clasify using DSCP default,af11,af21,af31,af41 and ef values to keep our carrier happy.
I have been doing some reading, but not making quick enough headway for my project. Any help that can be provided would be greatly appreciated.

Hey there,
Easiest way will be to use class-maps and policies, then apply them to the outgoing interface.
Using the class-maps, you can specify the traffic and in the policies set your traffic to ef, af11, etc.
Sorry if I'm teaching you how to suck eggs!
Hope it helps,

You can use modular QoS using class-maps. Below you can find a sample:
Create Classes to match traffic using NBAR or match them according to DF bit etc...
class-map match-all NNTP
match protocol nntp
class-map match-all HTTP
match protocol http
class-map match-all SMTP
match protocol smtp
Create the policy map and assign the bandwidth command
policy-map QoS
class HTTP
bandwidth percent 50
class SMTP
bandwidth percent 20
class NNTP
bandwidth percent 10
class class-default
bandwidth percent 20
Apply the QoS on the interface
interface Ethernet0/0
ip address 10.0.0.1 255.0.0.0
service-policy output QoS
Add the below config to the interface configuration to allow QOS to use all bandwidth
max-reserved-bandwidth 100
Verification:
R1#show policy-map interface ethernet0/0
R1#show queueing interface ethernet0/0
Make sure you enable Cisco CEF.
Please if you find the above helpful,
Regards,
