Adding a Virtual Port
Group
Port groups allow you to differentiate
between different kinds of traffic passing through a virtual switch. You can
also use port groups as a boundary for communication or for security policy
configuration. The default port groups for ESXi systems are
Management Network
and
VM Network
.
When you create a port group, you can specify a
VLAN ID for it. VLANs are an important part of ESXi networking because they
allow you to group traffic. For example, you could create separate network
segments for VMotion, for management and for development. Using VLANS, you only
need to have a separate uplink adapter for each network segment and a single
virtual switch connecting to that adapter. That setup can greatly reduce the
number of switches you need.
To add a virtual port group, use the following
steps.
- Define aHostPortgroupSpec. For each port group, you can specify the network policy, the VLAN ID, and the virtual switch to which the port group belongs.
- CallHostNetworkSystem.AddPortGroup, passing in thePortGroupSpec.
