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:
