For complete information, see zonestat(1).
The zonestat network component shows the usage of virtual network (VNIC) resources on PHYS, AGGR, Etherstub, and SIMNET data-links by zones. Information on other data-links, such as bridges and tunnels, can be obtained by using the networking utilities described in the dladm(1M) and dlstat(1M) man pages.
All zonestat options and resource types can also be invoked within a non-global zone to display statistics for that zone.
