Network Login
Network Login is a method of authenticating users as hosts are added to a network. As a new host is
added to the network, its port connection is in an unauthenticated state, denying any access to the
network. During authentication, the user supplies a password to the switch using the host. If
authenticated, the port connection is authenticated, and traffic flows to and from the host and the
network.
CLEARFlow
CLEARFlow is a broad framework for implementing security, monitoring, and anomaly detection in
ExtremeWare XOS software. Instead of simply looking at the source and destination of traffic,
CLEARFlow allows you to specify certain types of traffic that require more attention. Once certain
criteria for this traffic are met, the switch can either take an immediate, predetermined action; or it can
send a copy of the traffic to another device for analysis.
Software Licensing
Some Extreme Networks products have capabilities that are enabled by using a software key. Keys are
typically unique to the switch and are not transferable. Keys are stored in NVRAM and, once enabled,
persist through reboots, software upgrades, power outages, and reconfigurations.
Two level of software licensing apply to ExtremeWare XOS 11.1: the Core and the Advanced Core
license. Additionally, the U.S. government requires a security licensing to enable certain features.
Upgrading to Core License—Aspen 8810 Switch Only
The Aspen 8810 switch ships with the Advanced Edge license. With ExtremeWare XOS 11.1 on the
Aspen 8810 switch, you can obtain a Core license. The Core license provides additional functionality for
some features.
The license belongs with the switch chassis, not with the particular MSM module.
You can obtain a regular license; you cannot downgrade licenses. The key contains all the necessary
information on the license level.
NOTE
Refer to the specific chapter of the ExtremeWare XOS Concepts Guide to determine if the Core license is required
for some functionality. If not noted, all functionality is available, and license is not required.
If you attempt to execute a command and you do not either have the required license or have reached
the limits defined by the current license level, the system returns one of the following messages:
Error: This command cannot be executed at the current license level.
