Option Description
Notify Switches
Select Yes, No, or Inherit from vSwitch to notify switches in the case of
failover.
If you select Yes, whenever a virtual NIC is connected to the distributed
switch or whenever that virtual NIC’s trac would be routed over a
dierent physical NIC in the team because of a failover event, a
notication is sent out over the network to update the lookup tables on
physical switches. In almost all cases, this process is desirable for the
lowest latency of failover occurrences and migrations with vMotion.
N Do not use this option when the virtual machines using the port
group are using Microsoft Network Load Balancing in unicast mode. No
such issue exists with NLB running in multicast mode.
Failback
Select Yes, No, or Inherit from vSwitch to disable or enable failback.
This option determines how a physical adapter is returned to active duty
after recovering from a failure. If failback is set to Yes (default), the adapter
is returned to active duty immediately upon recovery, displacing the
standby adapter that took over its slot, if any. If failback is set to No, a
failed adapter is left inactive even after recovery until another currently
active adapter fails, requiring its replacement.
Failover Order
Specify how to distribute the work load for uplinks. If you want to use
some uplinks but reserve others for emergencies in case the uplinks in use
fail, set this condition by moving them into dierent groups:
n
Active Uplinks. Continue to use the uplink when the network adapter
connectivity is up and active.
n
Standby Uplinks . Use this uplink if one of the active adapter’s
connectivity is down.
N When using IP-hash load balancing, do not congure standby
uplinks.
10 (Optional) To congure trac shaping, expand  shaping, click Enabled, and specify the
following parameters.
Option Description
Average Bandwidth
Establishes the number of bits per second to allow across a port, averaged
over time—the allowed average load.
Peak Bandwidth
The maximum number of bits per second to allow across a port when it is
sending or receiving a burst of trac. This tops the bandwidth used by a
port whenever it is using its burst bonus.
Burst Size
The maximum number of bytes to allow in a burst. If this parameter is set,
a port may gain a burst bonus when it doesn’t use all its allocated
bandwidth. Whenever the port needs more bandwidth than specied by
Average Bandwidth, it may be allowed to temporarily transmit data at a
higher speed if a burst bonus is available. This parameter tops the number
of bytes that may be accumulated in the burst bonus and thus transferred
at a higher speed.
Trac shaping policy is applied to the trac of each virtual network adapter aached to the virtual
switch.
