Configure Global Settings for Application Mapping

Review the global settings that affect application mappings. Make any adjustments that are needed to customize application mapping behavior. The global settings that affect application mapping include the following options:

• TCP Rebase Port: Identifies a port for redirected TCP traffic. TCP traffic that you do not want to go to an application mapping target port goes to the TCP Rebase Port instead.
• ToS Mask: Determines whether all ToS bits are used for ToS values.
• UDP Rebase Port: Identifies a port for redirected UDP traffic -- comparable to the TCP Rebase Port setting.
• Preserve ToS Map Proto: Determines whether protocol values are reported in addition to ToS values.

Follow these steps:

1. Open the Application Definitions page:
   1. Select Administration from the NFA console menu.

      The Administration page opens.

   2. Select Application Definitions in the Administration menu.

      The Application Definitions page opens.

2. Click Additional Settings.

   The Application Settings page opens.

3. Review and correct the global settings that affect application mapping:
   • TCP Rebase Port: Identifies an alternate port to use for traffic that does not match the application mapping rules for the original target port.

     For example, suppose that you map all HTTP traffic on your Web Portal servers to TCP port 65550 and you set the TCP Rebase Port value to 63000. Port 65550 is reserved for HTTP traffic, so the non-HTTP traffic that would normally go to port 65550 is now sent to port 63000.

   • ToS Mask: Limits the 8-bit ToS values reported for NetFlow/IPFIX. The default value for this setting is 255, which enables all ToS bits.
   • UDP Rebase Port: Redirects nonmatching UDP traffic in the same way the TCP Rebase Port setting redirects nonmatching TCP traffic.
   • Preserve ToS Map Proto: Determines whether protocol values are reported in addition to ToS values. Y(es) retains the protocols that are used and reports ToS data separately. N(o) shows you the ToS values for traffic, but you do not see which protocols are involved. The default setting is Y.
4. Click Save.

   Your changes are saved. The Application Settings page remains open.
