A Client/Server policy maps a QoS treatment to traffic going between a server and
specific clients. You specify the both sets of endpoints (clients and server) between
which the traffic will travel. The server endpoint can also include an application
(translated to a Layer 4 port) or it can be a host (indicated by the application choice
"ANY," translated to an IP address only). The Policy System determines the switches
that are affected by this policy. The policy you specify is implemented as IP QoS in both
directions between the client and server. Although not shown in the diagram, you can
specify multiple servers as well as multiple clients.
Note: Specifying a large number of servers and clients can result in a very large
number of traffic flows. The diagram below (Figure 8-12) shows the number of
traffic flows generated for a simple example of two servers and two clients. For
"n" servers and "m" clients, the number of traffic flows afftected by the policy will
be m*n.
