Hi Guys,
We recently upgraded a 2960G(Only doing L2) that was hitting ~500Mb/sec on one
port, and we were seeing 40,000+ output drops (5Min) - Since the swap to the
4948, we see zero output drops. Is the difference in performance purely buffer
size? I *think* the 2960 has 1.9Mb (Per ASIC)

Same here. We went from 3560G's to 4948's and it was night and day. Zero
output drops now and a noticeable performance improvement, as we were using
these switches for ISCSI traffic. No qos tuning or disabling helped our
situation on the 3560G's.
What type of traffic were you sending through

2960/3560/3750 and 4948'sto go from 40,000+ drops to zero (5min) is a
significant improvement :)

the two platformsi.e. is it buffers/how they are allocated, architectural
differences or combination of both?
Cheers.

No...just genuinely interested in the differences between the 2 switches.

This documents may help answer your questions about buffer sizes and how
they are shared amongst ports on the two switches:

Look down at the QoS and queueing information (ignore the bits about
TelePresence)

Thanks Reuben - much appreciated.
