[f-nsp] Issue between FastIron (JetCore) and BigIron (IronCore)

Kevin,

 

There is a problem known, when you’re pc is on 100Mbps and the uplink is a gig in combination with QoS.

You have to adjust the buffers to get it working, it’s also in the releasenotes for the FGS.

Onderwerp: [f-nsp] Issue between FastIron (JetCore) and BigIron (IronCore)

 

Hello,

I have an issue with some of my Foundry Network.

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. 

Thank you,

Kevin Tunak
