Hello all,<br><br>Further to my previous post. The issue has not gone away I've now upgraded the BigIrons to ver 7.8.04 and the fastiron is now on 4.2.0. I've had to remove FSRP due to foundry versions not supporting it at the level I have moved to and I have now enabled VRRP.<br> <br>The issue still is that transfers between a device on the BigIrons running at 100mb and a device on the Fastiron running at a Gig is very slow one way the transfer is fine from the BI device to the FI device. From the FastIron to the BigIron is ridiculously slow. Just to add to this if I change the device on the FastIron to 100mb the transfers are fine both ways. If anyone has any idea how I can resolve this it really would be much appreciated.<br><br>Thanks<br><br>Kevin<br><br><br>------------Forwarded message------------<br>From: <a href="mailto:k.tunak@virgin.net" class="parsedEmail" target="_blank">k.tunak@virgin.net</a><br>Date: Jul 27, 2009 04:35:45 PM<br>Subject: Issue between FastIron (JetCore) and BigIron (IronCore)<br>To: <a href="mailto:foundry-nsp@puck.nether.net" class="parsedEmail" target="_blank">foundry-nsp@puck.nether.net</a><br><br>
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<br></body></html>
