VLAN C: vMotion Port Group-active on vmnic1 (to physical switch #2); standby on vmnic3 (to physical
switch #1.)

VLAN D: FT Logging Port Group-active on vmnic3 (to physical switch #1); standby on vmnic1 (to
physical switch #2.)
vMotion and FT Logging can share the same VLAN (configure the same VLAN number in both port
groups), but require their own unique IP addresses residing in different IP subnets. However, separate
VLANs might be preferred if Quality of Service (QoS) restrictions are in effect on the physical network with
VLAN based QoS. QoS is of particular use where competing traffic comes into play, for example, where
multiple physical switch hops are used or when a failover occurs and multiple traffic types compete for
network resources.

Create Cluster and Check Compliance in the vSphere Client
vSphere Fault Tolerance is used in the context of a vSphere HA cluster. After you have configured
networking on each host, create the vSphere HA cluster and add the hosts to it. You can check to see if the
cluster is configured correctly and complies with the requirements for the successful enablement of Fault
Tolerance.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Procedure
1 In the vCenter Server inventory, select the cluster and click the Profile Compliance tab.
2 Click Check Compliance Now to run the compliance tests.
To view the tests that are run, click Description.
