Thanks Dan - Our 2960 was doing a mix of Inet+VRF+backup traffic...so quite
bursty.
Really impressed with the difference between the 2960 + 4948...as you have
said...night and day.
Im really interested to find out if it's purely buffer size (And the way it's
allocated), or if there is a significant architectural difference between the
2960/3560/3750 and 4948's....to go from 40,000+ drops to zero (5min) is a
significant improvement :)

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 the 2960G?
Dan.

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) and the 4948 has 16Mb (total?)?
Cheers.
