Configuring system name and access settings
The
System administration
page (
System > Administration
) is used to configure the name of the
Expressway and the means by which it is accessed by administrators.
System settings
System name
The System name is used to identify the Expressway. It appears in various places in the web interface, and
in the display on the front panel of the unit (so that you can identify it when it is in a rack with other systems).
The System name is also used by Cisco TMS.

The System name is also used by Cisco TMS.
We recommend that you give the Expressway a name that allows you to easily and uniquely identify it.
Ephemeral ports range
You can specify the Ephemeral port range start and end values. This defines the port range to use for
ephemeral outbound connections not otherwise constrained by Expressway call processing.
ephemeral outbound connections not otherwise constrained by Expressway call processing.
The default range is 30000 to 35999.
Administration access settings
While you can administer the Expressway via a PC connected directly to the unit via a serial cable, you may
want to access the system remotely over IP. You can do this using either the web interface (via HTTPS) or
through a command line interface (via SSH).
