Well that indeed solved the 50-60% load I experienced with "route-only"<br>
configured on the interface. I'm still stuck 8% cpu-utilization on LP<br>
though. Is anyone on this list connected to AMS-IX with a CER or MLX(e), not<br>
experiencing this and willing to compare some interface configuration and<br>
debug packet captures?<br>

Hi,<br>
<br>
Since I'm working on 5500c, that's worth a try ;-)<br>
<br>
Thanks for your feedback!<br>
<br>

Onderwerp: Re: [f-nsp] Unexpected CPU load on NetIron CER<br>
<br>
Hi,<br>
<br>
> Has anyone seen similar behavior?<br>
><br>
> IronWare : Version 5.5.0cT183 Copyright (c) 1996-2013 Brocade<br>

><br>
<br>
when we started to test the CER 2024F-4x in our environment we discovered<br>
high cpu load as well, when using IPv6.<br>
<br>
"sh cpu lp" was at unusual high levels:<br>
<br>
09:15:15 GMT+01 Thu Sep 26 2013<br>
<br>
SLOT #: LP CPU UTILIZATION in %:<br>
in 1 second: in 5 seconds: in 60 seconds: in 300 seconds:<br>
1: 67 67 67 67<br>
2: 67 67 67 67<br>
<br>
The root cause was found in a high amount of ipv6 discovery and<br>
solliciatations.<br>
<br>
In our specific case it was fixed in 5500d, and the issue was traced back to<br>
the fix made for 459558 in 5500c.<br>
<br>
<br>
Best regards<br>
