STEP FOUR

The Encapsulation parameters for Frame Relay are less straight-forward. Many of them are based on decisions that cannot be shown in a diagram. Fortunately, the choices made here will mostly effect the performance of the link, rather than whether it works or not. Fill in the parameters appropriate for your system, consulting chapter 8 of the Installation Manual for more information if necessary.

Menu CONFIG=>INTERFACE=>SWAN=>ENCAPSULATION=>FRAME RELAY

Parameter	Example		Your Application
SNAP IP	Inactive for the example. The router on the
	sending end must be using the same header
	type (NLPID or SNAP) as the router on the
	receiving end.
LMI	ANSI for the example. This must also be
	the same as the router on the receiving end.
T391	Ten seconds, the interval between the LMI
	Status Enquiry messages.
N391	Six.
N392	Three.
N393	Four. This value must be larger than N392.
CIR	90 percent.	100 minus this number is the
	percentage of total bandwidth that may be
	discarded if the network is congested.
Bandwidth Reservation	Inactive. Traffic control will not be covered
	in this example

FIGURE 4.13 FRAME RELAY ENCAPSULATION MENU PARAMETERS

At the end of the parameter list shown above, the DLCI menu appears. Choosing Add DLCI will lead to the parameters shown in Figure 4.14. The <ESC> key used at any time during the Frame Relay encapsulation parameter list will also bring up the DLCI menu. A DLCI entry must be created for every remote Frame Relay network to be contacted. In the example, only one is shown.
