Remember to Check you Network Switch Firmware

FYI:

The issue was a problem with roaming between the TRI-Radio Access Points.

The partner installed about 12 AAP's connected to a RFS6000; the initial install seemed to go fine, but after about 3 weeks the users started to have roaming issues.  Of course the customer blamed the Motorola equipment.  The core switch was Cisco, all other switch's were HP.  The customer finally called in Cisco, who insisted it was the Motorola equipment.  After another week of gathering traces and setting up a duplicate network, we figured out the real issue was the firmware on the HP switches.

Lesson learned:  Make sure your customer's network switches are up to date.

We believe the issue was a failure to ARP correctly.

 

Y.11.01 was the original, upgraded to Y.11.16.

 

HP switch model was HP2510G-48. By the way none of the HP notes indicated an ARP issue:

Hi Dan, Do you know what the actual root of the problem was?

I'm guessing cam table refresh? John.

Interesting we are also experience issues with a HP infrastructure but not sure what the root cause is. Right now the MCD and WNS team are blaming each other....

HP model + firmware would be really helpful.

thanks
