Resolving Expand-Over-ATM Connection Problems
If the SCF STATUS LINE, DETAIL command displays CONNECTING in the Detailed
State field, use the SCF STATS LINE command to obtain further information about the
problem. Example 21-8 shows an SCF STATS LINE command.
If the line is configured to issue active connect requests, determine if Connect
Command frames (Conn Cmd column) are being sent (Sent row). If the line is
configured in passive connect mode, determine if Connect Command frames (Conn
QUERY A connection has been established
with the remote Expand-over-ATM
line-handler process, but no data
has been received within the
inactivity interval. The Expand-
over-ATM line-handler process is
sending Probe messages to the
remote Expand-over-ATM line-
handler process to verify that it is
operational.
If the line remains in this
state, the remote (destination)
Expand-over-ATM line-
handler process is down or
there is a network problem.
SETOPT_CALLING This is an internal state that should
not persist.
Try to restart the line. If this
state persists, contact your
HP representative.
SETOPT_LISTEN This is an internal state that should
not persist.
Try to restart the line. If this
state persists, contact your
HP representative.
WAIT The Expand-over-ATM line-handler
process is waiting for another
process or subsystem.
The line remains started but is not
ready for data transfer.
See the Detailed Info field for
more specific error
information. Recovering from
these types of problems is
described further in Resolving
Expand-Over-ATM Wait
