Using Frame Relay
13
Frame Relay is a method of encapsulating network information that allows for fast
delivery and high line utilization. PortMaster routers support Frame Relay over
synchronous ports.
This chapter uses an example to demonstrate how to configure the PortMaster to
connect to a synchronous line using Frame Relay. This chapter also explains how to
configure Frame Relay subinterfaces
The following topics are discussed:
•
“Overview of Frame Relay” on page 13-1
•
“Frame Relay Configuration on the PortMaster” on page 13-4
•
“Configuration Steps for a Frame Relay Connection” on page 13-7
•
“Troubleshooting a Frame Relay Configuration” on page 13-11
•
“Frame Relay Subinterfaces” on page 13-12
See the
PortMaster Command Line Reference
for more detailed command descriptions and
instructions.
Overview of Frame Relay
Synchronous ports on PortMaster products can be configured to support Frame Relay
connections. As opposed to a dedicated or leased line, a Frame Relay connection can be
thought of as a virtual switch.
Frame Relay is a switched digital service that supports multiple virtual circuits,
simultaneously connected to a site by a single physical circuit. Each site requires only
one physical circuit into the Frame Relay network—usually referred to as a cloud—but
can have several virtual circuits to reach other sites attached to the cloud.
