Reason and Refuse Codes
(0x82) Connection Negotiation Failed
May be a problem with the classes specified
(transport over CONS error).
Check to see if remote only
uses class 0. If so you might
reconfigure the local stack to
force class 0.
(0x83) Duplicate Source Reference for Same NSAP
This is a protocol error.
The caller must generate a
unique reference number for
each connection it forms.
(0x84) Mismatched References
Either a protocol error, or may indicate that
the remote stack was taken down and
brought back up while existing connections
remained.
Check the state of the remote
stack.
(0x85) Protocol Error Check any logged
information on the remote
side. Also verify the stack was
not being brought up at the
time.
(0x88) Connection Request Refused on this Network
Connection
The level of multiplexing configured for the
local node may not be compatible with that
on the remote.
On HP systems, examine the
Transport over CONS
parameters
tpcons_max_con_mux_in
and
tpcons_max_con_mux_out
and change if max out exceeds
max in.
(0x8A) Header or Parameter Length Invalid
Indicates a protocol error.
Check log information on
remote.
(0xE4) X.25 Network Error or Network Down Run x25stat to determine
the status of the X.25 link.
May need to restart X.25 or
reset other X.25 hardware.
