administration program, or are presented differently. These differences

 

are indicated in the following sections where they apply.

 

Connectivity Resources

 

 

Connectivity to remote systems is supported by the following resources:

 

DLCs (see “DLCs”).

 

 

If you use the Motif administration program to configure a port, the

 

 

corresponding DLC definition is created automatically. For

 

 

command-line administration, the DLC is configured separately.

 

Ports (see “Ports”).

 

• Link stations (see “Link Stations”).

 

• Connection networks (see “Connection Networks”)

If you use the Motif administration program, you can define a connection network as part of port configuration. For command-line administration, a connection network is configured separately.

DLCs

A DLC is the component responsible for communication over a physical link (or multiple links) using a specific data link protocol, such as SDLC or token ring. Each DLC can manage one or more ports, as described in “Ports”.

SNAplus2 provides support for the following data link protocols:

Synchronous data link control (SDLC)

X.25 QLLC (qualified logical link control), for which the X.25 communications software may be provided by your SNAplus2 supplier or by another supplier

Token ring

Ethernet (standard or IEEE 802.3)

FDDI (Fiber Distributed Data Interface)
