This chapter provides scenarios for configuring the WAN and Serial ports
for dial-up with PPP, Frame Relay, or X.25.
After completing basic configuration on the ports and paths as described
in Chapter 6, complete the scenarios in this chapter appropriate to your
network.
You should not attempt to take any configuration files from a model 4xx
bridge/router and move them to a model 5xx bridge/router.
This section includes dial-up scenarios for the built-in ISDN port on the
model 43x, 44x, 53x and 54x bridge/routers and for the serial ports on all
models.
Bandwidth management features that can be enabled after configuring
the ports and paths are described in Table 17.

Feature Description
Dial-on-demand or To dial out on the ISDN and serial lines, you
manual dial can configure dial-on-demand or manual
dial. Dial-on-demand automatically dials the
destination bridge/router when network
traffic is present and hangs up when the
network is idle. Dial-on-demand also
provides failover support. If the primary line
goes down, the bridge/router will failover to
another available dial-up line, either from a
dial pool or from another path assigned to
the same port. To dial manually, use
NETBuilder commands to dial and hangup.
