Configuring SNA

Configuring a Hunt Group for SNA Subscribers
Hunt groups are described on
page 8-24
. The function has some special requirements
for SNA routing:
●
Each SNA port in a routing path must have a unique network address, even if it
will not be used explicitly by the routing table.
●
Configure two ports as SNA HPADs, one (called HPAD1 for this list) with
Round Robin specified and one or more routing paths configured, and the other
port (HPAD2) with any routing algorithm but only one routing path.
●
The Port parameters for each port specified in the Routing Paths of each HPAD
must contain a Remote Subscriber ID for any TPAD that might call either
HPAD. (The Remote Subscriber ID in the HPAD's Port configuration is the
Local Subscriber ID in the TPAD's Port configuration.)
●
Include HPAD2 in HPAD1's routing path.
●
Configure only one routing path for each TPAD.
●
In Port configuration, disable Autocall for each HPAD and enable it for each
TPAD.
●
In Port configuration, configure HPAD1's Local Subscriber ID as the only
Remote Subscriber for each TPAD.
When the host polls the HPADs, they will become operational. The TPADs will
autocall and the HPADs will connect to the TPADs by Round Robin. Since all the
TPADs are configured to connect to HPAD1 (which has HPAD2 in its routing path),
they will be connected to HPAD1, then HPAD2, then HPAD1, and so on.
If HPAD1 fails, all calls will be routed to HPAD2 until HPAD1 is again operational.
Configuring LLC2
Configuring a Virtual LAN ID
A virtual LAN ID is normally assigned by a system administrator. The ID is used
internally by the FRX4000/6000 to identify a virtual bridge that connects the LLC2
function to LAN interfaces.
If LLC2 will run in the local node, press
[B]
at the Configure IP/LLC2/BRIDGE/IPX
Default Parameters Menu
(or
[A], [A], [E], [B]
from the Main Menu). When prompted,
enter:
●
Virtual LAN ID:
0–fff
(hex). (The default is
000
.)
LAN IDs can also be configured in LLC2 Interface/Bridge
Port records (later in this chapter). Each Virtual LAN ID
must be unique among all LAN IDs throughout the network
on which this node will operate.
●
If also configuring Bridging in the node, address the remaining parameters as
described in
Chapter 15
. Otherwise, press
[Enter]
(accepting the default) for
each remaining parameter, since they are not used for LLC2.
