Defining Connectivity Components
Defining Link Stations
If you do not know what value to use, consult your SNA
network planner.
If the remote end of this link is a VTAM host, the SAP
number is the SAPADDR= parameter of the VTAM
PU definition.
If you are configuring a link to an AS/400 system, the
MAC address is the ADPTADR parameter in the Line
Description.
Additional Link Station Parameters for X.25 (QLLC).
Circuit type
Specify either
Permanent virtual circuit
or
Switched virtual circuit
to indicate whether the
circuit is permanent or switched.
Channel ID
The channel ID that identifies the virtual circuit the
link station is to use (only applicable for a permanent
virtual circuit). Channel IDs are numbered from 1 up
to a maximum of 4096. If you have only one permanent
virtual circuit, its channel ID is likely to be
1
.
Remote X.25 address
The DTE address of the remote DTE as a series of
hexadecimal digits (only applicable if the circuit is a
switched virtual circuit).
Adapter/Port Number
The card number (if your card has only one port). If you
have only a single card, use a value of
0
.
If your card has more than one port, use the value n
p
x,
where n is the card number and x is the port number.
For example, the first port on the first card should be
specified as
0p1
.
SpiderX25 stacks use an adapter number and a port
number to support multiple X.25 cards, each with
possibly multiple physical ports. Cards are numbered
starting at 0; ports are numbered starting at 1.
To determine the card and port number to use, use a
string that matches the end of the device name of the
X.25 driver. For example, use an adapter/port number
of
0p1
for an X.25 driver named
/dev/x25_0p1
.
