NOTE: NAT devices may not be connected between the DSView 3 server and any managed appliances.
Licenses
License keys permit the operation of the DSView 3 management software on the hub server. They 
also specify the number of managed devices that may be controlled by the software and spoke 
servers allowed on a system. Managed devices include physical servers, routers, switches, 
firewalls, blade chassis, hypervisor managers, hypervisor servers, virtual machines and any other 
target device that can be managed by the DSView 3 software. If a managed device is available 
through multiple connection methods, the managed device requires only one license as long as it is 
merged into a single connection in the DSView 3 software.
Licenses may also be required to enable additional features. See Table 4.8 on page 55 for more 
information.
A demonstration (demo) license key may also be used for a trial period. When the trial elapses, 
login attempts will fail. A demo license key may be replaced with another demo license key or a 
permanent license. If additional license keys are added during the trial and the demo key expires, 
the add-on keys will have to be re-entered when a new license key is installed.
Contact Avocent for information about obtaining licenses.
