zx25d 406 The zcntl() to retrieve firmware revision codes for the X.25
link ZLU <#> unexpectedly failed with error <#>.
Explanation: When an X.25 link is initialized for the first time, the
X.25 protocol driver issues a zcntl() control write
request to retrieve the version codes of the X.25 and
HDLC/LAP-B firmware to determine if the driver is
compatible with the version of firmware being used by
the MUX card. This request has unexpectedly failed.
The MUX will be assumed to be running with
compatible firmware. This error should have no impact
on the operation of this X.25 link.
Action: Check the error returned against those listed in this
guide and take corrective action as necessary. If the
problem persists and you are unable to determine its
cause or the error code indicates a probable internal
defect, contact your HP support representative.
zx25d 407 The zcntl() to configure the X.25 link ZLU <#>’s timers
(T1, T2, T3/T4) has unexpectedly failed with error <#>.
Explanation: When the X.25 driver receives notification that X.25 at
level 2 (HDLC/LAP-B) has been established, it issues a
request to set the X.25 level 2 protocol timer values. It
issues a zcntl() control write request to set the T1, T2,
and T3/T4 timer values with the indicated error. The
X.25 driver will ignore this error and continue to
attempt to bring the link up. Note: If abnormal
behavior is observed on the link, the X.25 link should
be shutdown and re-initialized.
Action: Check the error returned against those listed in this
guide and take corrective action as necessary. If the
problem persists and you are unable to determine its
cause or the error code indicates a probable internal
defect, contact your HP support representative.
