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 port 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.
Call detail records (CDRs)
The system can capture CDRs if you enable the service (which is off by default), and can publish them as
syslog messages if you are using remote logging.
syslog messages if you are using remote logging.
If you select Service only the system keeps the CDRs for 7 days, and these CDRs can only be read via the
REST API to the Expressway. If you select Service and logging, the local data is exposed in the Event log,
and the CDRs are also sent as INFO messages to your syslog host.

CDR reporting is best effort and the CDRs cannot be relied upon for accurate billing purposes.

The local 7 days worth of CDR data is written to disk. It is preserved over a system restart/reboot, and is
included in the backup/restore process.

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).
