We are upgrading a customer network and have found that users of a particular application [which is very bursty/bandwidth hungry] have experienced a marked performance drop. I see lots of output drops on the interfaces. This is only happening on 2960S-48 the rest of the users on 2960PSTL [all PoE] are not having nearly as bad a time.
I have tried various QoS configs with little success. I have seen on some other blogs that the 2960S has less buffers than the rest of the family. An idea of this is true?
Removing QoS or upping the users to 1Gb cures the performance problem.
TIA
