3Com NETBuilder SI, SuperStack II manual Advanced Configuration Ports and Paths

ADVANCED CONFIGURATION OF

7 PORTS AND PATHS

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.

Configuring Dial-UpThis section includes dial-up scenarios for the built-in ISDN port on the

Lines with PPP 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.

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.
