Ronald,<br><br>I found the document you refer to and used the buffer settings suggested however this has not improved the performance at all. <br><br>Basically I just added the following commands to cover all the ports. <br><br>buffer-profile port-region 0 voip downlink 100 uplink 1000<br>buffer-profile port-region 1 voip downlink 100 uplink 1000<br><br>Is there something I have missed ? Is there any addtional configuration needed at the Bigiron end.<br><br>Thank you<br><br>Kevin<br><br>Jul 28, 2009 09:15:39 PM, <a href="mailto:ronald.esveld@qi.nl" class="parsedEmail" target="_blank">ronald.esveld@qi.nl</a> wrote:<br><blockquote style="border-left: 3px solid rgb(102, 153, 204);">

<b>Onderwerp:</b> [f-nsp] Issue between FastIron (JetCore) and BigIron
(IronCore)</span></p>

<p class="MsoNormal"></p>
<p class="MsoNormal">Hello,<br>
<br>
I have an issue with some of my Foundry Network.<br>
<br>
I have a BigIron 8000 (IronCore) with a Management 3 Module with 8 Fibres and a
number of 24 port 10/100 modules. MM3 Software version 8.0.0.1 ( I have also
tried from around 6.5 upwards). The BigIron is set as a layer 3 switch which
manages traffic between the 20 or so VLAN's we have set up. <br>
<br>
I also have a FastIron GS648P software version 3.1.00 set up as just a standard
Layer 2 switch. (I have also tried up to version 4). In this I have an E1MG-SX
Fibre Module.<br>
<br>
The problem I have is when I connect these switches together with a Fibre Lead
I seem to have slow file transfer speeds between a PC patched in the BigIron
and a PC patched into the FastIron. However when I connect the FastIron to a
BigIron (same modules) set up with Switching code only the transfers are fine.<br>
<br>
I recreated this problem in a test lab using the spare BI4000 and FastIron
GS648P we have. I have also tried a Management 2 module with the same results
fine layer 2 slowness on layer 3.<br>
<br>
Is there some sort of issue interconnecting these 2 devices when the BI is
configured as a Layer 3 Route/Switch ?<br>
<br>
I think the configuration should be fine I've basically just tagged in the
VLAN's needed on the 2 Fibre ports. No configuration on the actual fibre
connections. This is done exactly the same as the rest of my network which
consists of 9 BigIrons varying from 4000 to 8000's and none of these have had
this issue.<br>
<br>
Any help would be gratefully received. <br>
<br>
Thank you,<br>
<br>
Kevin Tunak</p>
