Cabletron Systems FRM User Manual - Configuration Examples

Frame Relay Module 4. 0 User G uide, Rev 01
Most parameters can be specified and/or changed using the operations
described throughout the configuration portion of this manual; others, such
as RLP and port number, are defined by the hardware or specified during
software installation.
Configuration Examples
Legacy Protocols over Frame Relay via Logical Ports
Below is a sample configuration and guidelines for configuring Logical Ports for
Annex G or RFC 1490 transmission over frame relay.
Figure 3-1 Configuration Example 1
Configure the following in each FRM:
●
RLP parameters
(Chapter 5), to configure the RLP(s) that contain the ports over
which the protocols will run. Each serial protocol (SNA, async, BSC, X.25,
frame relay) must be configured on the RLP that contains the port.
●
Physical port
(Chapter 6 plus Chapter 7 [Frame Relay], Chapter 8 [X.25],
Chapter 9 [SNA], Chapter 10 [BSCI], and Chapter 12 [Async]).
●
Logical port
(Chapter 8) on the physical frame relay port that connects to the
network. (Note that logical ports are numbered 8–63, because 0–7 are the
physical ports.)
●
SVC subscriber
(Chapter 7 [Frame Relay], Chapter 8 [X.25], Chapter 9 [SNA],
Chapter 10 [BSCI], and Chapter 12 [Async]), which assigns static addresses
used to route the call request packets of the physical access ports to the logical
port and vice versa. Subscriber addresses are based on the X.121 Called Address
field.
●
Optional SVC subscriber records (static routes) for any attached X.25 DTEs.
These are needed to identify the attached DTEs’ X.121 Calling Addresses. If an
X.25 Call Request is received from the WAN link, the FRM needs to know
where to route the call.
