[e-nsp] EAPS - Fail-timer-exp flag set. Domain state: Complete

[Fabian]

Hi Mikeld,

 

This message should appear when the EAPS Master is losing EAPS PDU that it
has sent over the ring.

Loss of EAPS Health-Check Packets could happen:

-          Frames in error in the ring

-          A switch in the ring that is having some trouble and loosing
frames

-          Lot of frames going to CPU on the Master

-          ..

 

Wireshark will not really help because EAPS PDU are isolated in the Control
VLAN.

 

If this happened on all rings, I will check the Common Link (or EAPS
Shared-Link) status/statistics.

 

Fabian.

No matter whether it is XOS Version 12.4.1.7 v1241b7-patch1-7 nor EW-Version
7.8e.2.1, at a certain time, mainly between 12.00 to 01.00 pm I get
hundreds of messages in the syslogs like

There are nearly all EAPS-Master from 24 EAPS-Rings affected. My
investigations shows the following: 

All the eaps-rings have no configuration errors. 
There are no rx- or tx-errors on the uplinks. 
Network performance is not affected. 
It must be a certain vlan from which the interference comes, this vlan is
known. 
It happens only on weekdays and during office hours 
I have no details found with wireshark, but I'm not an expert with wireshark

I found some references about IPv6 neighbor discovery protocol, there are
some W7 PCs in that vlan. 

My guess is that something teases the cpu of the eaps-masters but how can I
catch that thing? 
Does anyone have a suggestion how I can get this under control with EW or
XOS or wireshark or anything else? 

Thanks a lot, Mikeld
