Port Alias Configuration
Packet Analyzer Plus and AppResponse 11 use port aliases in display names.
The default ports and aliases are based on the IANA definitions. These TCP and UDP port aliases can be added to or revised to match your network traffic. For example, if your network uses a nonstandard port to carry SIP traffic, you can add that port with the TCP and/or UDP sip alias to the port aliases. If none of your SIP traffic runs on the default port, you can delete the port or change the alias to identify the TCP and/or UDP protocol that does use the port in your network.
AppResponse displays a name for unidentified network traffic from the protocol/port number (port alias) defined, for example, TCP/2753 (de-spot). If no port alias is defined just the protocol and port are used when displaying the name.
Default port alias names use lower case letters, numbers, and special characters. Auto-recognized traffic uses upper and lower case letters, numbers, and special characters. This convention eases traffic identification when viewing traffic in Insights and Navigator.
Use the Port Definitions page to:
◼ Assign a recognizable name (alias) to an individual TCP/UDP port.
◼ Edit or delete an existing port alias.
This section addresses the following:
Configuring a Port Alias
A port alias can be used by one or more ports. A port can only have one TCP alias and/or one UDP alias defined.
Configure a port alias as follows:
1. Choose Definitions > Port Aliases to open the Port Alias Configuration page.
2. Click Add in the tool bar at the top of the table.
3. In the New Port Alias window, enter the following:
– Port—A port number must be between 1 and 65535.
– TCP alias—Enter a name if needed. Names can use letters, numbers, and special characters. By convention, alias name are in lower case.
– UDP alias—Enter a name if needed. Names can use letters, numbers, and special characters. By convention, alias name are in lower case.
4. Click Save to store or click the x in the top right corner of the window to discard.
