698 C HAPTER 22: Q UALITY OF S ERVICE (Q O S) AND RSVP
The value that you enter for the start of the range determines the default
for the end of the range. The end value must be greater than or equal to
the start value.
To avoid severely affecting applications using the network, select a port
range that is as small as possible (for example, a single port).
11 Enter the start of the TCP or UDP destination port range, in the range of
from 0 through 65535 . The default is 0 .
12 Enter the end of the TCP or UDP destination port range using a value of
up to 65535 . The end value must be greater than or equal to the start
value.
13 At the prompt, specify whether you want any other filters (address and
port patterns) with this classifier ( yes or no ). The default is no .
If you specify yes , the system prompts you for additional information,
beginning with the source IP address.
Flow classifiers classify traffic only at the network layer and therefore
affect only traffic that is being routed from one subnetwork to another.
