Resolving The Problem

This document provides information on the error recovery path for Gigabit
Ethernet running TCP/IP; it is different than on older interfaces.

Sometimes you will see an IP interface active and working, even though the
Ethernet line description is in a status of RCYPND.

This is normal.

Answering message CPA57E9 (with G or R) will initiate recovery of the
system objects and should not affect TCP/IP.

(You could also an IP interface active and working, even though the
Ethernet line description is in a status of RCYCNL. )

To automate the answering of message CPA57E9, use the Work with Reply List
Entries (WRKRPYLE).

The communications path used by TCP/IP for Gigabit Ethernet interfaces is
different than older interfaces. Therefore, TCP/IP handles its recovery
separately from the recovery processing for the system for the line,
controller, and device objects. TCP/IP recovers when it is informed that
the link is back up. The system recovery is driven by the CMNRCYLMT
configured for the line. If those recovery limits are exceeded, recovery of
the system objects waits for a response to an operator message without
regard to the physical link status.

The system object recovery method for Gigabit is the same as for any other
line and is not considered an error. In this case, forcing the TCP/IP
recovery to wait for the system object recovery does not seem desirable.
This is considered a permanent restriction.

We have a client that would like to get email notifications of alerts.

As an example the attention light was on and the cause was the Ethernet
line failed overnight. I suspect there was some network maintenance.

So the orange light is on and I get an email enquiring why.

My investigation finds the Ethernet line failure and subsequent recovery.

I am not aware of any default way to get an email if a problem is created
- I'm sure there are API's and most likely SQL options to read current
problems so if I want to write something that would be one place to start.

Is there anything already provided on the system that can be turned on /
set up that would achieve the same result ?

Thanks

Don
