We got following error messages.
=====================================================
11:25:18 KORST 26 Feb 2007 1536-14(0-10) E (s2)
GDLC detected LS outage.
LS = ETHLINK2
Outage = protocol error (-906)
11:25:18 KORST 26 Feb 2007 512-60(0-10) P (s2)
An active link station has failed.

Conversation ended by session outage.
TP name = SNARECV1
=====================================================
We have no system error log 'errpt' at this time.
What is a cause of that error?
What is major situation?
and... Where can I find error code (-906)???
thanks...

The "protocol error (-906)" comes from the GDLC layer,
which is part of AIX and sits between CS/AIX and the
adapter. Look at /usr/include/sys/gdlextcb.h which has:
#define DLC_PROT_ERR -906 /* protocol error */
The frame that caused the error never made it up into
CS/AIX, it was thrown away at the GDLC layer:
CS/AIX Linkstation
CS/AIX Port
CS/AIX DLC
AIX GDLC
AIX ethernet device driver
ethernet adapter
You would need a sniffer trace to see why the frame was
determined to have a protocol error. Where there any
corresponding errors at the remote end or on an intermediate
bridge/router/switch? For example, if an intermediate
bridge was reset and decided to change from 802.3 ethernet
to Standard (V2) ethernet, the AIX GDLC would see that as
a protocol error.

I am suprised there was not an 'errpt -a' entry created by
the GDLC layer. Were there any 'errpt' entries with a
matching timestamp, even if that errpt entry was just hex data?
