[e-nsp] EXOS 15.3.2 on X650 - EAPS + stacking (and multicasts)

[Marcin Kuczera]

hello,

we have done many changes in main switch architecture recently.
We have 2x X650-24x in stacking mode, however slot-2 was disconnected 
for a while.

Yesterday we have upgraded switches with:
- 4x40G modules
- 15.3.2.11 EXOS

And we have some issues and a big problem ;)

1. remember that when you install VIM3-40G4X in stacking mode, the 
switch will boot and... will search for master forever so
you can't login beacue aaa is pending all the time.
Problem is caused by SystemType change:
System Type:      X650-24x(SS) (Stack)
System Type:      X650-24x(40G4X) (Stack)

There is some magic command to override it, but we didn't know it so 
reconfiguration took a time..


2. EXOS 15.3.2.11 is something that I suppose you should not install on 
X650.
Multicasts just work randomatically. I mean - there are random problems 
that i.e. particular vlan on particular port
just doesn't forward multicasts strems it was requesting.
On another port - it works. No info from log files, any debug shows that 
stream should be available - but it is not.

Testing is done by mirroring particular ports traffic to LINUX and 
looking into tcpdump.

There are many changes in multicasts in 15.3.2 that migh not be tested 
on X650 platform...

As a result we will go down to 15.3.1.4 patch 1-18. Before we had 
15.3.1.4 patch 1-3, working fine but with some issues related to 40Gx4 
module (patch1-18 fixes this)


3.  EAPS..... we have 2 EAPS ring.
When both slots (1-2) become connected, slot 1 is master, slot 2 is backup.
For one of EAPS instances our stack is Master.

And - in master log we have:
09/19/2013 14:34:47.44 <Warn:EAPS.RxAnotherMaster> Slot-2: EAPSD 
eaps-ktw-glw-domain - Received Health-Pdu from another Master 
(02:04:96:36:C5:65) on the same domain.
09/19/2013 14:26:24.16 <Warn:EAPS.RxAnotherMaster> Slot-2: Previous 
message repeated 503 additional times in the last 502 second(s)

So, every 1 second a message.

Is this a BUG or stacking is not configured properly ?
