Strange issue of upload faster than download speed

Recently moved to HP for our core and our residential wireless network has been significantly slower with faster uploads than downloads.  So if you unplug the aruba ap from the HP switch and then plug in directly a laptop speeds are normal.  Wondering if there is a MTU size issue? Any help would be greatly appreciated.

Look on the interfaces to see if you see any errors on the HP interfaces

by default in all brands its on auto... look onthe interface that it sincronized with the correct speed  at 1000


You are doing this test when noone is using the network?

I tell you this because HP switches cisco switches etc oversubcribe the speed they can handle... they think that noone will ever use all the ports at maximum speed.

Which core you used to had before HP?

Yes I would always hard code your uplinks (1000FDX) to the controller.  we saw the same issue with our HP 5412 switch and the aruba controller.  The HP side would negotiate to 1000HDX and the aruba to 1000FDX obviously this causes some major issues :)

 

You should see something in your HP logs as well possibly stating a duplex mis-match

Thank you for replying, no errors on the interfaces.  Testing during normal times of day.  We had Cisco core prior.  Will double check interface speed settings as well.  Thank you.

Hey CFritz,

 

I am experiencing the same issue and was wondering if you ever found a resolution?  Thanks!

I know this is a late reply, but we never found a conclusive resolution.  We ended up changing some other core switches and the numbers then seemed to begin to even out.

Re: Strange issue of upload faster than download speed

For us it turned out to be an old configuration copied from when we used Cisco Wi-Fi running on the controller that did not impact layer 2 switches. Once layer 3 switches were introduced the configuration hampered the communications between the controller and AP's tied to the Layer 3 switches. Deleting the old configuration cleared up the issue.
