The VLAN200 in "class-map match-all VLAN200" is just specifying the
class-map-name. From the IOS docs: "Name of the class for the class map.
The class name is used for both the class map and to configure policy for
the class in the policy map." I believe you would use service-policy to
attach it to a VLAN interface. You don't need "match-all" as you only have
one match statement in the class-map.
class-map match-all VLAN200
Match access-group 103
policy-map VLAN200-policy
class VLAN200
priority percent 75
class class-default
fair-queue
The above should set the minimum guaranteed bandwidth (Percent "Specifies
that the amount of guaranteed bandwidth will be specified by the percent of
available bandwidth") IF the traffic matches ACL 103, and if it does not
match then it will default to the "class-default" and fall into using 256
dynamic queues (assuming the interface was > 512Kbps bandwidth).
It's all in the IOS documentation.

Subject: class-map, access-lists, access-groups, and policy maps [7:72643]
I have been looking for a simple explanation as to how the three relate
and their dependencies. Example configuration from a show run:
class-map match-all VLAN200
Match access-group 103
Does the above subject all VLAN200 traffic to access group 103?
Is that access group associated with the access-list?
policy-map VLAN200-policy
class VLAN200
priority percent 75
class class-default
fair-queue
What does the above do, allocate a maximum bandwidth, or set a priority
queuing?
I have been looking for a good reference to QoS policy's and how to
determine what the router has set. Any recommendations?
