Comparing The Alliedware Plus Version Numbers And Feature Licenses - Allied Telesis AT-x550-18XTQ Installation Manual

Comparing the AlliedWare Plus Version Numbers and Feature
Licenses
This procedure is optional. It explains how to compare the following
information about the two switches of the stack:
 AlliedWare Plus Version Number: The procedure explains how to
view the version numbers of the AlliedWare Plus management
software on the switches. This is important because when the
switches of a stack are powered on or reset, the master switch
compares the version number of its AlliedWare Plus management
software with the software on the member switch. If the two units
have different versions, it automatically downloads its management
software to the member switch over the stack trunk, so that both
switches have the same version. By determining ahead of time
whether the two switches have different software versions, you can
select the master switch of the stack to be the switch with the
newer version of the operating system, thus avoiding the situation
where a master switch with an older version of the management
software replaces newer software on a member switch.

Optional feature licenses: It is also a good idea to check whether
the switches have optional Allied Telesis feature licenses. If one
switch has an optional feature license and the other does not, the
switches can still operate as a stack, but the additional features are
only available on the switch with the license. To resolve the issue,
you can add the license to the switch without it either before or
after connecting the stacking cables.
To view the management software version numbers and optional feature
licenses on the switches, perform the following procedure:
1. Start a local or remote management session on one of the switches to
be in the stack. For instructions on how to start a local management
session, refer to "Starting a Local Management Session" on page 91.
2. When prompted, enter the manager name and password to log on.
The default values are "manager" and "friend", respectively.
The switch displays the Use Exec mode prompt, shown here:
awplus>
3. Enter the ENABLE command to move from the User Exec mode to the
Privileged Exec mode:
awplus> enable
awplus#
4. In the Privileged Exec mode, enter the SHOW SYSTEM command:
