Bandwidth Policies vs. Bandwidth Shaping

© Copyright Lenovo 2017
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 G8264CS. 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 G8264CS. 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 G8264CS. 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.
