Installing Optional Feature Licenses
You may now install the optional premium and AMF master licenses.
Please review the following information before installing a feature license:
When ordering a feature license from Allied Telesis for the stack,
you must order two licenses, one for each chassis. However, you
use only one license to activate the feature. The active controller
card automatically copies new feature license to all the controller
cards in the stack, thereby activating the license on both switches.
For example, to install the premium feature license on a stack, you
have to order two premium licenses from Allied Telesis and then
use one of the licenses to activate the feature on the stack.
Feature licenses are installed with the LICENSE command in the
Privileged Exec mode. For instructions, refer to the Software
Reference for SwitchBlade x8100 Series Switches.
Feature licenses for the AT-SBx81CFC400 Controller Fabric Card
are not compatible with the AT-SBx81CFC960 Card.
