Index numbers and changing default port numbers

An index number is assigned to each of these services. The index numbers assigned can vary over time. If you want to change the network port number for a service, enter a “set service” or “show service” command to display the current index number assigned to all services. Locate the service for which you want to change the network port number, and note the index number for the service. Enter a “set service” command, specify that index number for the “range” option, and the new network port number for the “ipport” option.

For example, to change the network port number for the Telnet basic service from its default port number, 23, you would enter the following “set service” command:

#> set service

which displays the services defined in and their current network port number assignments:

Service Configuration :

10	on	50000	na	na	Modem Emulation (Pool)
11	on	50001	off	off	Modem Emulation (Port 1)

Note that the index number assigned to the Telnet basic service is 1. You would then specify that index number for the “range” option, and the new network port number for the “ipport” option:

#> set service range=1 ipport=100
