VM Profile Bandwidth Shaping differs from VM Policy Bandwidth Control.
VM Profile Bandwidth Shaping (see
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 CN4093. 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 CN4093.
VM Policy Bandwidth Control is configured per VE, and can be set independently
for transmit and receive traffic. Bandwidth policies are enforced by the CN4093.
VE traffic that exceeds configured levels is dropped by the switch upon ingress (for
txrate) or before egress (for rxrate). Setting txrate uses ACL resources on the
switch.
Bandwidth shaping and bandwidth policies can be used separately or in concert.
The CN4093 can be used to display a variety of VMready information.
Note: Some displays depict information collected from scans of a VMware vCenter
and may not be available without a valid vCenter. If a vCenter is assigned (see
"Assigning a vCenter" on page
to two minutes after the switch boots or when VMready is first enabled. Also, any
major changes made through the vCenter may take up to two minutes to be
reflected on the switch unless you force an immediate vCenter scan (see
Scans" on page 269).
A concise list of local VEs and pre-provisioned VEs is available with the following
