Defining Connectivity Components
Defining Ports, DLCs, and Connection Networks
This field applies only if the adapter card can support
more than one port.
This field is not used for SDLC or QLLC ports.
Initially active
Whether to activate the port automatically when the
node is started. This setting enables link stations that
use the port to be activated in response to requests
from adjacent nodes or on demand by the local node.
(Activating the port does not activate any link stations;
link stations are activated separately.)
Additional Port Parameters for SDLC
Line details
The following parameters describe the type of SDLC
connection:
Type
Select one of the following values:
Leased Line
A dedicated line is used for the SDLC link between this
computer and the remote system.
Switched incoming
The standard telephone network is used for incoming
calls.
For a nonprimary port (as indicated by the Link role
field), you also need to configure the poll address (for
outgoing calls, that address is configured on the link
station). The poll address is a one-byte address (C1 by
default) that needs to match the poll address
configured at the remote link station. When active, the
port responds to frames sent with this poll address.
For a primary port, you do not need to configure a poll
address; the port uses the poll address specified by the
remote link station on the incoming call. For other
types of ports, the poll address is configured on each
link station.
Switched outgoing
The standard telephone network is used for outgoing
calls.
