Optional Feature Licenses

44
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 also offers additional features and capabilities
for the switches. These features come with the AlliedWare Plus operating
system, but they have to be unlocked before you can use them. The
features are unlocked with feature licenses from Allied Telesis. For a list of
optional feature licenses for this 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 may install feature licenses while the switches are operating
as stand-alone units or as 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 optional feature licenses. To resolve the issue, you
can use the ATMF REMOTE-LOGIN command to log onto the
switch without the license, and install the license. For more
information, refer to the Software Reference for x550 Series
Switches, AlliedWare Operating System from
