Configuring SNA 9-3
Figure 9-1 SDLC and LLC2 Examples
Required Configuration
To run SNA in an FRX4000 or FRX6000, make sure the following are correctly con-
figured:
●
Node parameters , which is general configuration that must be done no matter
which protocols will be run in the node. See Chapter 4.
●
RLPs that will contain the interface(s) to the user device(s), plus Line Interface
Card(s) supporting the ports that will be the interfaces. See Chapter 5.
●
Loaded Protocol(s) : SNA, as well as the transport protocol: frame relay or X.25;
and LLC2 if connecting to LLC2 devices or if if the transport protocol will be
frame relay. If LLC2 will be used, Bridging must also be loaded. See Chapter 5.
●
If LLC2 is being configured, LAN port that will connect to the LAN(s). See
Chapter 5.
●
Frame relay port(s) and/or X.25 port(s) that will connect to a network or frame
relay PVC. See Chapter 7 (frame relay) or Chapter 8 (X.25).
●
SNA port(s) (page 9-4) that will connect to the user devices, if the connection
will be SDLC.
●
SNA HPADs and TPADs (described later in this chapter), which identify any
SDLC devices that will communicate with SNA host and terminal devices.
●
LLC2 hosts (page 9-18) and LLC2 interfaces (page 9-26), if the SDLC device(s)
will be connected to the node via a LAN, or if SDLC will be transported over
frame relay per RFC 1490.
●
Subscriber IDs (page 9-14) to identify the user devices if SNA will be trans-
ported onto the frame relay link via a logical X.25 port.
●
If LLC2 is being configured, Virtual LAN ID (page 9-17). Since an FRX4000/
6000 is seen to LLC2 as a virtual LAN, an ID must be specified to identify the
node to LLC2.
