For example, you can enter:
changeport 1744
Or,
changeport
to use the specified port number.
If you change the port after installation, CiscoWorks will not launch from Start
Note
menu (Start > Programs > CiscoWorks > CiscoWorks). You have to manually
invoke the browser and specify the URL, with the changed port number.
The restrictions that apply to the specified port number are:
There is no reliable way to determine whether any other service or application is
using a specified port. If the service or application is running and actively
listening on a port, it can be easily detected.
However, if the service is currently stopped, there is no way that the utility can
determine what port it uses. This is because on Windows there is no common port
registry equivalent to /etc/services as in UNIX.
The port number must be a numeric value in the range 1026 – 65000. Values
outside this range and non-numeric values are not allowed.
When you execute the utility with the appropriate options, it displays messages
on the actions it is performing.
It lists out all the files that are being updated. Before updating, the utility will back
up all the affected files in CSCOpx\conf\backup and creates appropriate unique
sub-directories.
It also creates a new file index.txt, which contains information about the changed
port and a list of all the files that are backed up and their actual location in the
CiscoWorks directory.
