The GE ports on a VS-S720-10G-3C supervisor are each provisioned with 9.6MB
RX and 8.1MB TX buffers.  This is quite a respectable amount of buffer
space for a GE port, although if you have mls qos enabled, the default TX
configuration is 1p3q4t, configured as:

SP: 1.2MB
Q3: 1.2MB
Q2: 1.6MB
Q1: 4.1MB

This may not suit your traffic profile if everything is in a default
priority class, as you'll end up putting everything into q1.
