SCF Commands
The SCF INFO PROCESS $NCP, NETMAP command is useful for displaying the
current routing data. Example
20-5 on page 20-9 shows a sample display of the SCF
INFO PROCESS $NCP, NETMAP command. Asterisks indicate the best-p
ath route. A
plus sign (+) instead of an asterisk (*) would indicate that the Expand subsystem is
attempting to connect or reconnect a path.
140 This error indicates that the
Expand line has been
disconnected. The cause could
be a problem with modem-to-
system communications or with
a phone line, a cable, or an X.25
connection.
For IP, ATM, and ServerNet
lines, this error
usually means
that the ASSOCIATEDEV line
modifier is incorrectly
configured, or an error in
communication with the local
ASSOCIATEDEV process
(TCPIP, ATM, or $ZZSCL).
Examine the physical connections and modem
setting
s to ensure that cables are plugged into
the correct line interface unit (LIU).
Check the configuration of the
ASSOCIA
TEDEV line modifier, if an IP, ATM, or
ServerNet line is involved.
Check the CPU that the TCP/IP process is
runn
ing on.
Check the access list of the SAC to make sure
tha
t the line-handler process can access the
SAC.
164 This error can be generated
when
you attempt to start a
SWAN direct or satellite line. It
means a DISC (disconnect)
frame was received from the
remote system.
The line should recover by itself when this error
is se
en, so no recovery is required unless the
problem persists for more than one minute. If
the error persists, a hardware problem can be
indicated. Examine the log file and contact your
HP representative.
248 This error is often generated
when
a line is started. The line is
electrically operational, but data
communications with the
neighbor node have not yet
occurred.
Possible causes include the
ne
ighbor Expand line-handler
process has not yet started; the
NEXTSYS modifier at the
neighbor node does not match;
there is a FRAMESIZE
mismatch.
If the neighbor Expand line-handler process
has no
t yet started, use the Expand subsystem
SCF START command to start the line-handler
process.
If the NEXTSYS or FRAMESIZE modifier is
incorrect, correct it using the WAN subsystem
SCF ALTER DEVICE command.
