My apologies, I see that you are applying the service-policy to a map-class
(didn't read through your post as closely as I should have). Since you are
doing that, you will need to do it the way Bob suggested. However, you can
apply the service-policy output to the entire interface without using
frame-relay traffic shaping and have the class match only on the specified
DLCI with the "match fr-dlci 103" class-map command. From your config
above, it looks like you are applying the service policy outbound. If
you want to matching on incoming packets, then you need to apply your
service-policy inbound, but then you can't shape. You will have to police.
