Legacy Protocols over Frame Relay via Logical Ports

3-2
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.
Below is a sample configuration and guidelines for configuring Logical Ports for
Annex G or RFC 1490 transmission over frame relay.

Configure the following in each FRX4000/6000:
RLP parameters (Chapter
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.

Logical Port (Chapter

physical ports.)
SVC Subscriber (Chapter 7

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 FRX4000/6000 needs to
know where to route the call.
