.

Step 2

For all connection settings except for global timeouts, configure a service policy according to

Customizing the TCP Normalizer with a TCP Map

To customize the TCP normalizer, first define the settings using a TCP map.

Detailed Steps

Step 1

To specify the TCP normalization criteria that you want to look for, create a TCP map by entering the
following command:

hostname(config)# tcp-map tcp-map-name

For each TCP map, you can customize one or more settings.

Step 2

(Optional) Configure the TCP map criteria by entering one or more of the following commands (see

Table 53-1

). If you want to customize some settings, then the defaults are used for any commands you

do not enter.
