2: BSCTRAN Commands and Options
DC 900-1406E 21
2.1.1 Server Field in BSCTRAN Commands
Many of the BSCTRAN commands include a server parameter. Note that this parame-
ter contains a pointer that allows the Freeway software to determine a DLI session name
and thus a board number and a link number, by referencing the configuration files.
Consider the following example. Suppose you want to use the
SHOW command to display
the configuration of a particular link on a particular ICP. To do this, use the
SHOW com-
mand with the following parameters:
SHOW 2 FWY0_0
The “2” indicates link 2. The “0” following the underscore indicates ICP 0. The FWY0
before the underscore is the server parameter (the first four characters of the DLI ses-
sion name) that acts a pointer. Following is a description of how the BSCTRAN soft-
ware uses this information to select the desired link and ICP board.
2.1.2 How the BSCTRAN Command Determines the Data Path
The BSCTRAN software combines the information in the BSCTRAN command into a
session name as follows: the
server parameter, followed by a “B,” followed by the board
number, followed by an “L,” followed by the link number. Continuing the above exam-
ple, the BSCTRAN software would combine the information in the
SHOW command into
the following session name:
FWY0B0L2.
The software then checks the
dlitrancfg (or dlitetrancfg) configuration file and
locates the section that defines the designated session. In our example, it would locate
the following session section:
FWY0B0L2
{
.
Transport = "bsc0"; // Connection Name //
BoardNo = "0"; // ICP board number //
PortNo = "2"; // Link number //
.
