Software Description
OS
The RingMaster appliance runs on the Linux operating system. The WLM1200-RMTS does not provide
any means of accessing the OS shell to run arbitrary commands.
CLI
A Command Line Interface (CLI) is provided through a serial port. This interface allows configuration of
platform-related settings and is equivalent to that of the platform configuration Web interface. The CLI
provides a subset of the functionality provided by the Web interface. For details, see Using The Command
Line Interface below.
Web
The WLM1200-RMTS supports a Web interface for configuring RingMaster tunables plus a new interface
for configuring platform-related settings like networking, date/time, etc. The RingMaster configuration Web
interface is accessed via HTTPS on port 443. You have the option as to whether or not access control
should be enabled for this interface. The WLM1200-RMTS’s platform configuration Web interface is
accessed via HTTPS on port 8003. Links in both interfaces allow navigation between the two. Access
control is always enabled for the platform configuration Web interface. There are two users — admin and
monitor — defined for the platform settings Web interface.
Image Upgrade
WLM1200-RMTS software is distributed as a single image containing both the OS and the RingMaster
application. The installation procedure is based on an active/standby partitioning scheme where the new
software is setup in the standby partition. The system does not reboot itself as part of an upgrade. The
upgrade sets up the standby partition. You must make upgrades effective by manually rebooting the
system. If anything goes wrong during an installation procedure, the system resorts to running the
previously active partition.
A Web-based mechanism is also provided for you to manually revert to the previously active partition at
any time. If this revert operation is invoked, the state of the RingMaster application (plans and monitoring
database) also reverts to the state at which the previous installation occurred.
Factory Reset
The WLM1200-RMTS supports a CLI-based mechanism to reset the platform and RingMaster application
settings back to default settings. This operation does not affect the executable software running on the
appliance. It resets the configuration to a default state compatible with currently active software. Any
existing RingMaster plans as well as the monitoring database are cleared as part of this operation. All
licensing information is also deleted.
A mechanism is provided to reset the admin password should you forget it. This mechanism is only
provided through the CLI on the serial port. The reset operation does not affect any other platform
configuration other than the password.

WLM1200-RMTS™ User Guide
Licensing
License Distribution
The WLM1200-RMTS is shipped with a license certificate for 250 APs. You must install and activate the
base license and all additional AP licenses.
Appliance Installation
Complete instructions regarding site preparation, unit unpacking and equipment installation are provided in
the publication WLM1200-RMTS Hardware Setup Guide including information on cabling connections to
the unit from a power source and for networking interfaces.
Platform Configuration
Initial RingMaster Setup
When the WLM1200-RMTS is shipped, RingMaster software is already installed, including the latest OS
and RingMaster software. When powering up for the first time, the only function available to you is the
setup wizard. You use this initial setup wizard to specify basic platform information, such as how to connect
to a network, before appliance functionality is enabled. This wizard is implemented as a CLI-based
mechanism accessible through the appliance’s serial port.
When you connect to this port, you are prompted for the following information:
Hostname
Networking
−Selection of DHCP or static IP
−If static IP
>IP address and netmask
>Default gateway
>IP address of primary name server and domain name
Administrator password — The wizard uses this to set up a user named admin.
Command Line Interface
A command line interface is supported on the appliance’s serial port. The commands supported provide a
subset of the functionality provided by the Web interface.
Specifically, the following is supported:
Networking
Image Upgrade
Factory Reset
Shutdown/Reboot
The one CLI-only function is the factory reset command.

Forgotten Password Recovery
If the administrator of a system forgets the password of the user admin, the following method can be used
to reset the password to the empty password so that the system can be accessed as admin with no
password required. The password can then reset to a secure one via the CLI.
The procedure is as follows:
1. Boot the system to single user and execute a script to reset the admin password in the active
database. If any database corruption is suspected, the script resets the system database to its
initialized default. The admin password is not set in such a database. A system booted to single user
mode does not require a privileged user password. The system can be rebooted by power cycling. It is
assumed the person using this procedure is able to access the system’s console and can see the
entire boot process (this is either over a serial console or the system’s direct console).
2. Once the system is starting to boot, the following GRUB message should be seen (GRUB is the boot
loader for the system):
Grub Loading stage 2...
Press any key to continue.
[This message repeats (once a second) on a new line several times, and if no key is pressed the system
boots normally. You should press a key to enter the GRUB command line]
.
.
.
Press any key to continue.
[Assume the user presses the space key (for example)]
3. Next, you should see the following GRUB text which allows you to select one of the 2 images to be
booted. Choose the desired image by using the arrow keys so that GRUB indicates that the desired
entry will be booted.
GRUB version 0.93 (640K lower / 259536K upper memory)

Use the ^ and v keys to select which entry is highlighted.
Press enter to boot the selected OS, 'e' to edit the
commands before booting, 'a' to modify the kernel arguments
before booting, or 'c' for a command-line.
Highlighted entry is 1:
If a selection is not made within a few seconds, the system will automatically boot the image that is
highlighted. You should press the ekey to enter the edit command mode. This will give you the ability to
change command options that are part of the boot process. Specifically, you will add the option single to
force the system into single user mode.
When the ekey is pressed, the GRUB text shown below will be seen. (Note the 0and 1entries now refer
to the selected image that is booting). You should now edit the kernel line. This is done using the arrow
keys on your keyboard to select the 1: line — press the down arrow key one time. The message at the
bottom should now indicate Highlighted entry is 1:
GRUB version 0.93 (640K lower / 259536K upper memory)
-------------------------------------------------------------------
0: root (hd0,1)
1: kernel /vmlinuz ro root=/dev/hda5 console=tty0 console=ttyS0,9600n8
-------------------------------------------------------------------
Use the ^ and v keys to select which entry is highlighted.
Press 'b' to boot, 'e' to edit the selected command in the
boot sequence, 'c' for a command-line, 'o' to open a new line
after ('O' for before) the selected line, 'd' to remove the
selected line, or escape to go back to the main menu.
Highlighted entry is 1:
4. After selecting the 1: kernel command line, press the ekey to edit this line.
5. After e is pressed, you should see the grub edit> prompt. If the line is long enough, you may only see
a portion of the end of the text. For example, in the above when the 1: kernel line is:
kernel /vmlinuz ro root=/dev/hda5 console=tty0 console=ttyS0,9600n8
after 'e' is pressed, the user may see the following
<yS0,9600n8
The <indicates the a portion of the command line is not seen. The arrow keys allow you to
navigate the command line.
The option single should be appended to the end of this line. For example:

Highlighted entry is 1:
It should be noted that two 'console' options appear on the kernel line. In this example, the latter is the
serial console and the former is the direct console. The console option that appears last is used. If the
procedure is used on the direct console, the order of the two console options should be changed or the
serial one (console=ttyS0,9600n8) should be deleted.
6. When done editing the kernel line, press the <enter> key followed by the bkey to resume booting the
selected image. After more boot messages a root user prompt will be displayed:
sh-2.05b#
7. At this prompt, run the following command:
/sbin/resetpw.sh
If successful, the admin password is now reset to an empty password. If any corruption of configuration
state is detected, an attempt to save existing configuration databases is made and the system’s
configuration state is reset to initial values — i.e. the same state as when the system was manufactured.
In this case, the admin password will be set to the 'empty' password. The command will notify you of any
locations of saved configuration state.
sh-2.05b# /sbin/resetpw.sh
Admin password reset successful.
