Figure 3. 15 Viewing the security settings for the built-in Guest Dynamic IP virtual
port profile
An uplink port profile defines the connectivity of the virtual switch to logical
networks. You need separate uplink port profiles for each set of hosts that require the
same physical connectivity (remember that logical networks define the physical
network). Conversely, anytime that you need to restrict logical networks to specific
hosts in the same location or need custom connectivity, you will require different
uplink port profiles. Logical networks can be selected that will be available as part of
the uplink port profile and NIC Teaming configuration, when used on hosts that will
assign multiple network adapters. No inbox uplink port profiles are supplied because
their primary purpose models the logical networks that can be connected to, and by
default there are no logical networks. If a change is made to the uplink port profile
definition (for example, adding a new VLAN that is available), SCVMM will
automatically update all of the virtual switches on the Hyper-V hosts that use the
uplink port profile via a logical switch with the new VLAN availability or any other
settings within the uplink port profile.
Putting all of these components together does require additional up-front work.
However, the long-term deployment and manageability of the environment becomes
much simpler and can help you identify misconfigurations or problems in network
connectivity.
The logical switch is a Live Migration boundary for SCVMM’s placement logic. Note
that a logical switch can be deployed to many hosts, it can stretch clusters, and so on.
However, SCVMM needs to ensure that the same capabilities and connectivity are
available when virtual machines are moved between hosts, and so the SCVMM
