Cabletron Systems 1800 Switch User Manual


 
Configuring SNA 9-17
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 an LLC2 Virtual LAN ID
A virtual LAN ID is normally assigned by a system administrator. The ID is used
internally by the SmartSwitch 1800 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 16. Otherwise, press
[Enter]
(accepting the default) for
each remaining parameter, since they are not used for LLC2.
