Frame Relay PVC Passthrough

Figure 3-2 Configuration Example 2

Make sure the following are configured in each SmartSwitch 1800:

Protocols (

Chapter 5

), to load the frame relay protocol.

Physical frame relay port (

Chapter 6

and

Chapter 7

). Configure the SmartSwitch

1800 port to the 3174 as logical DCE, and the port to the frame relay switch as
logical DTE.

Frame relay PVC (

Chapter 7

), which links the two frame relay ports in the

SmartSwitch 1800. The DLCIs are defined in the PVC record; if rate control
(CIR, BC, BE) will be enforced, be sure to configure those parameters in the
frame relay Port record.

Make sure each DLCI is supported on the attached device.

LLC2 PUs over Frame Relay to AS/400

Figure 3-3 Configuration Example 3

Make sure the following are configured in each SmartSwitch 1800:

Protocols (

Chapter 5

), to load frame relay, LLC2, and Bridging (required for

LLC2).

LAN Interface parameters (

Chapter 6

), to configure the Ethernet interface on the

SmartSwitch.

Physical Port parameters (

Chapter 6

and

Chapter 7

), to define the frame relay

port.

Virtual LAN ID (

Chapter 9

), which identifies a virtual bridge that connects the

internal LLC2 function to the Ethernet interface.
