About using the frame relay protocol; frame relay port and DLCI rate configuration; configuring frame 
relay backup groups; logical port configuration; viewing frame relay management, congestion, and 
error stats

FRX and SmartSwitch 1800 ports which have been conÞgured to use frame relay 
as their layer 2 protocol can be used to carry both frame relay trafÞc and trafÞc 
from other protocols which has been encapsulated in frame relay (per RFC 1490).

Each frame relay port can contain multiple logical ports Ñ up to 56 on an 
FRX4000 and SmartSwitch 1800, and up to 56 per RLP on an FRX6000 Ñ and each 
logical port is assigned a Data Link Connection IdentiÞer (or DLCI), which 
identiÞes a point-to-point connection. All 56 logical ports can reside on one 
physical port, or be spread among several ports, and each can be conÞgured to 
run one or more layer 3 protocols.

For each physical port conÞgured to run frame relay, four conÞguration windows 
and three statistical windows are provided:

¥

The Frame Relay Port ConÞguration window allows you to conÞgure basic 
operational parameters related to the frame relay protocol, and displays some 
general information about the serial port itself and the line to which it is 
connected;

¥

The Frame Relay DLCI Rate ConÞguration window allows you to select the 
data rate parameters for each DLCI conÞgured on the selected frame relay 
port;

¥

The Frame Relay Backup Groups window allows you to conÞgure backup 
groups for primary DLCI connections;

¥

The Logical Port ConÞguration window allows you to conÞgure basic 
parameters related to logical port operation;
