HP Procurve 2610 - File tranfer at 512Kbps

[BenForMile]

Hi,

I'm not sure if I'm posting this on the right forum but here it is.

I have a HP Procurve 2610-24-PWR (J9087A). When we do file transfer from computer to computer via workgroups the file transfer is limited to 512K transfer rate. On our old office we had a couple of unmanaged switches and we use to transfer files faster. Do know what might be causing this? I have 100 Full-Duplex on almost all ports and some are set to auto. Duplex speed on the ports are sets according to status alerts I get on the web interface.

We have gigabit cabling done on our new office with a gigabit patch panel. Later we are planning in upgrading this switch to a gigabit switch, but at the moment this is the only option for us. Also I'm using the HP Procurve 2610 web interface to change some settings. I'm new to manage switches so please bare with me, my boss want me to learn how to manage this switch.

Thank You
Ben

Having gigabit cabling and patch panel, etc... does not mean you still could not have a cabling issue. If your cabling is run to close to a object that throws off EMI (light balast, air condition unit, high voltage cable, etc...), then you're going to have issues. If the installers didn't follow AT&T 568B code, you could have problems. The only way that you can know for sure is if your installer, using a level 4 scanner, ran tests on the cable plant and left you a printout of those findings and everything certified OK.

If you know your cabling is good, then you could use a crossover cable (568B to 568A) from computer to computer and get the switch completely out of the picture to test your file transfers. I really doubt your switch is the culprit, but this would confirm to you for sure.

Let us know what you find.

Figure out which switch interfaces are carrying this traffic (in and out) and then do a "Show interface..." on each of them. Look at status and statistics, including error count.

A crossover cable is not "568B to 568A!" Constructing such a cable would leave the blue and brown pairs uncrossed, and would definitely not help you troubleshoot anything.

A network crossover cable is most definetly one side 568B starting with the orange pair and splitting the green pair (ow,o,gw,b,bw,g,brw,br) while the other side is 568A starting with the green pair and splitting the orange (gw,g,ow,b,bw,o,brw,br).
You might be thinking of a rollover cable used for serial communication to a router or switch. But a crossover cable as I described is 100% legitimate to troubleshoot this scenario as it negates the need of two computers to talk to each other via a switch. They just connect to each other using a crossover cable. He can then do his file transfers straight from computer to computer without the switch in the middle to confirm if he has as switch issue or a computer issue.

I'm not mistaken on cable type. I know what kind of cable you are suggesting, and why. However, the method you describe is incorrect! It swaps the green/orange pairs, but NOT the blue/brown pairs. In other words, you recommend the following pinout:

1 ----- 3
2 ----- 6
3 ----- 1
4 ----- 4
5 ----- 5
6 ----- 2
7 ----- 7
8 ----- 8

When the correct pinout should be:

1 ----- 3
2 ----- 6
3 ----- 1
4 ----- 7
5 ----- 8
6 ----- 2
7 ----- 4
8 ----- 5

Sure, it'll probably come up at 100mbit, depending on the NIC... and probably leave the original poster wondering if one of his NICs is the problem, since they won't come up at gigabit speeds over a 10' patch cable.

I do stand corrected if he is testing at 1Gb; however, my suggestion is still 100% valid as he is only connecting at 100Mb to his switch, so why convolute the matter if he is able to connect at 1Gb on his card and give him a false comparitive to what he was connecting to via his 100Mb switch.

Does the PC say its connected at 100mb but you only get 512kb when transferring files? have you tried with computers direct into the switch?
