Command History
Usage Guidelines When you specify the source-address keyword, each flow with a unique source address is treated as a
new flow.
When you specify the destination-address keyword, each flow with a unique destination address is
treated as a new flow.
A policy map is called a flow-based policy map when you configure the flow keywords on the class map
that it uses. To attach a flow-based policy map as a child to an aggregate policy map, use the
service-policy command.
Note The match flow command is available on the Catalyst 4500 series switch only when
Supervisor Engine VI (WS-X4516-10GE) is present.
