Kevin,
That should to the trick. I would suggest to make a mirror port on the bi to see how packets come in and analyse that. We had problems in the past with the buffers, but not like this….

Basically I just added the following commands to cover all the ports. buffer-profile port-region 0 voip downlink 100 uplink 1000 buffer-profile port-region 1 voip downlink 100 uplink 1000 Is there something I have missed ? Is there any addtional configuration needed at the Bigiron end.

You have to adjust the buffers to get it working, it’s also in the releasenotes for the FGS. Ronald Met vriendelijke groet, With kind regards, Fout! Bestandsnaam niet opgegeven.

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. 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. 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. 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. Is there some sort of issue interconnecting these 2 devices when the BI is configured as a Layer 3 Route/Switch ? 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. Any help would be gratefully received.
