Configuring SNA
11-19
Configuring LLC2
LLC2 support in the FRX8000 includes the following scenarios, some of which are
diagrammed in
Figure 11-1
(on page 11-1).
●
Connection between a LAN-attached host/workstation and SNA devices, via
SDLC-to-LLC2 and LLC2-to-SDLC conversion, over a frame relay or X.25
network (example 1), or frame relay PVC (example 4).
●
Connection between LAN-attached workstations, over a frame relay or X.25
network (example 2), or a frame relay PVC (example 3).
●
Connection between workstations attached to different LANs on the same
FRX8000.
Configuring a Virtual LAN ID
A virtual LAN ID is normally assigned by a system administrator. The ID is used
internally by the FRX8000 to identify a virtual bridge that connects the LLC2 function
to LAN interfaces. If LLC2 will run in a node, this ID must be configured in the Node
Defaults file (
[A], [B], [A], [C]
from the Main Menu).
Press
[1]
at the main Node Defaults screen to display FRX8000-specific parameters.
If item H (
SNA LLC2 Virtual LAN ID
) is not configured as the necessary
ID
, press
[H]
and,
when prompted, enter the value, in the range
0–fff
(hex).
LAN IDs can also be configured in LAN Card records (described
in
Chapter 6
) and LLC2 Interface records (
page 11-25
). Each
LAN ID must be unique within the network on which this node
will operate.
Configuring LLC2 Hosts
Each SNA/LLC2 host device that will connect to an FRX8000 running LLC2 must be
configured in the database. To configure a host, press
[A]
, then
[C]
from the SNA LLC2
Management Menu (or
[A], [E], [C], [A], [C]
from the Main Menu). When prompted,
enter:
●
Node ID
:
1–250
. (Default is the “local” node.)
●
Host Number
:
0–128
. (Default is
0
.)
●
Type
:
1–3
. (Default is
0
.) Press
[1]
to configure parameters that define a host.
Press
[2]
to configure an Originated host connection, and press
[3]
to configure
a Terminated host connection.
In an Originated session, the host initiates LLC2 sessions; in a Termi-
nated session, the host accepts sessions destined for the address. (A
host-to-terminal connection is always initiated by the terminal.).
●
(Originated host connection only)
Connection Number
:
1–16
. (Default is
1
.).
This is simply an identifier for the connection.
●
(Terminated host connection only)
Remote SVC Number
:
1–16
. (Default is
1
.).
This matches a
Connection Number
on the remote host.
●
Any other requested information, noting
