Configuring Dial-Out Connections 7-3
Configuring the Location Table
Table 7-1 Dial-Out Connection Types
To configure the connection type, use the following command:
Command> set location Locname on_demand|automatic|manual
On-Demand
Dial-on-demand connections to selected locations can save money because the
telephone line is used only when traffic needs to be transmitted. The dial-on-demand
configuration can also be used as a backup for other types of connections such as those
using high-speed synchronous lines. A dial-on-demand connection usually has the idle
timer set so that the connection is closed when no longer needed.
Note – When configuring a dial-on-demand location, be careful not to have the
on-demand location be the route to the loghost, RADIUS server, RADIUS accounting
server, or any host for a port using the PortMaster login or device service, unless you
understand the effect of these services upon dial-on-demand.
If routing for a dial-on-demand location is set to on, listen, or broadcast, the
PortMaster dials out to that location when it boots, to update routing information. The
PortMaster hangs up when the idle timer expires because RIP traffic does not reset the
idle timer.
To configure a location to support a dial-on-demand connection, use the following
command:
Command> set location Locname on_demand
Automatic
To establish an automatic dial-out connection, you must set the location type to
automatic. In this configuration, the PortMaster dials out after it boots and establishes
a network connection to the specified location. If the connection is dropped for any
reason, the PortMaster dials out again and establishes the connection again after a
30-second wait.
Connection Type Description
on_demand This type of connection is automatically started when
packets for the remote location are queued by the
PortMaster.
automatic This type of connection is always active. If the telephone
connection is dropped, the PortMaster initiates a new
connection with the location after a 30-second waiting
period.
manual This type of connection is started when you request a
connection. You can use this configuration to test a
connection or for network callback users. This is the default.
