<br>
<br>
We have had a number of 10ge-4-port card crashes on SE600 running
SEOS v11 and have been advised by Ercisson to upgrade to 12.1.1.6,
however, I have seen a number emails regarding 10GE card crashes
on 12.1.1.6 which is quite worrying. Does anyone have experience
of stable v12 code with 10GE cards, especially in an L2TP/LNS/LAC
environment?
<br>
<br>
Any feedback regarding version 12 experiences appreciated!

4x10G card is PPA3 based<br>
1x10G card is PPA2 based<br>
<br>
In 12.1.1.7p1 ericsson has resolved important crash problem for PPA3
based cards, while PPA2 cards problems still exists.<br>
<br>
So, if you have only PPA3 based cards - use 12.1.1.7p1<br>
Also several other issues have been fixed.<br>
<br>
If you have a very heavy load in meaing of fetures and functions on
a single node, probabilty of crash increases.. on a SE600 that acts
as a BGP only - 12.1.1.5p2 and no crashes on record..<br>
<br>
<br>
btw, as additional workaround for any possible future crashes - use
2x 4x10G cards and create link-groups access mode (cross cards). In
a case of a crash (single card crash) the other card in link-group
continues operation with a little hiccup for switchover. No multiple
simultanous crashes occur.<br>
<br>

Marcin<br>
