Bandwidth Policies vs. Bandwidth Shaping

© Copyright Lenovo 2016
VM Profile Bandwidth Shaping differs from VM Policy Bandwidth Control.
VM Profile Bandwidth Shaping (see "VM Profiles" on page
VM group and is enforced on the server by a virtual switch in the hypervisor.
Shaping is unidirectional and limits traffic transmitted from the virtual switch to
the G8264. Shaping is performed prior to transmit VM Policy Bandwidth Control.
If the egress traffic for a virtual switch port group exceeds shaping parameters, the
traffic is dropped by the virtual switch in the hypervisor. Shaping uses server CPU
resources, but prevents extra traffic from consuming bandwidth between the
server and the G8264. Shaping is not supported simultaneously on the same ports
as vNICs.
VM Policy Bandwidth Control is configured per VE, and can be set independently
for transmit traffic. Bandwidth policies are enforced by the G8264. VE traffic that
exceeds configured levels is dropped by the switch upon ingress. Setting txrate
uses ACL resources on the switch.
Bandwidth shaping and bandwidth policies can be used separately or in concert.
