Optional Feature Licenses

74
The x550 Series switches comes with the AlliedWare Plus operating
system and a base set of features that are available as soon as you install
the devices. Allied Telesis offers additional features and capabilities for
the switches. They come with the AlliedWare Plus operating system, but
have to be unlocked before you can use them. Unlocking optional features
requires licenses from Allied Telesis. For a list of optional feature licenses
for the product, refer to its product sheet on the Allied Telesis web site.
Here are the guidelines to feature licenses for a stack of x550 Series
switches:
 The VCStack feature is part of the base features of the switch. It
does not require an additional feature license.
 You can install feature licenses while the switches are operating as
stand-alone units or a stack.
 When ordering feature licenses for the switches of a stack, you
must order one license for each switch.

The switches will form a stack even if they have different feature
licenses. However, the additional features are only available on
those switches that have the necessary licenses. The stack
generates a warning message if it detects that the switches do not
have the same feature licenses. To resolve the issue, you can use
the ATMF REMOTE-LOGIN command to log onto the individual
switches in a stack to install new licenses. For more information,
refer to the Software Reference for x550 Series Switches,
