FRM Conf iguring Frame Relay 7-3
Figure 7-1 Frame Relay Backup Examples
Although each example shows a connection between a SmartSwitch
1800 and an FRX6000, connections can be between any two devices
in the family of SmartSwitch 1800, Frame Relay Module (FRM),
FRX4000, and FRX6000.
Example 1
In Example 1, the primary link is between Node 1/Port 2/DLCI 16 and Node 2/RLP
0/Port 0/DLCI 18. The DLCIs should be configured as described below. (The param-
eters are described later in this chapter.) Then if the primary link goes down, a con-
nection will automatically be established between Node 1/Port 0/DLCI 17 and Node
2/RLP 0/Port 4/DLCI 17.
On Node 1, configure the following (as well as other parameters necessary for oper-
ation—this section deals only with the frame relay backup function):
1. Port Configuration ( [A], [C], [A] from Main Menu) for the primary:
RLP: 0
RLP Port: 2
O Additional Parameters
D Configure DLCI Parameters
DLCI ID: 16
I DLCI Backup Configuration
A
Backup Group Number: 10 (or any unused number except 0 )
B Enable Backup Protocol?: N
E For Backup Use Only: N
