TermDSM Commands
DI[AG] XN[ETWORK]
DI[AG] XN[ETWORK]
Determines if the connection to the network is functioning properly.
This test is executed only if the SNP is not started.
Security level: 2.
Syntax
XN[ETWORK] dtcnum,cardnum,
destination address
Parameters
dtcnum The number TermDSM associates with a particular
DTC. The DTC command lists each DTC with its
assigned number. This list is also printed when you
make a mistake while typing in a DTC number.
cardnum Number of the interface card within the DTC to which
the device is connected. The cards are numbered from
zero beginning at the bottom of the DTC. (Note that
SNP cards may not be mounted in slot 0 or 1 for
DTC 16, and slot 0 for DTC 48.
destination address
The X.25 address. This address has a total of 15 digits.
Description
Determines if the network is functioning properly by testing the
connection between an SNP and the network. The test tries to send and
receive data from the network. To do this, a VC is opened with a
destination address on the local side. The correct X.25 address must be
configured in the Level 3 Configuration screen in NMMGR.
Additionally, this address must be entered as the last parameter of the
SNP network loopback command. This test is executed only if X.25 is
not started on this SNP (X25 Level 1, 2, and 3).
All loopback tests are disruptive in the sense they will abort any
existing VC connections on that SNP. Other SNPs in the DTC will not
be effected.
When the subcommand is entered the following question is asked:
Do you want to stop looping if an error is found (yes/no)?
If you answer yes, the loopback tests will stop if an error is
encountered. The following is then printed on the terminal:
Please connect and make ready an X.25 network (power on, X.25 line
correctly configured, etc.) connection to the SNP card, before
answering the “How many times?” question.
