Definition - What does Port-to-Application Mapping mean?
Techopedia explains Port-to-Application Mapping
By using host-specific port mapping, users can use the same port number for different services on different hosts. For example, it is possible to map port 8000 with Hypertext Transfer Protocol (HTTP) services for one host and map the same port with the telnet service for another host. These mappings permit the users to apply PAM to specific subnets when they run services using port numbers different from those specified in the default mapping information.
The ip port-map configuration command is used in establishing the port-to-application mapping. The no form of this command deletes the user-defined PAM entries.
