ager Reference Manual.
Known Problems
A non-administrative user cannot run 3WXM.
(12155)
3WXM generates an exception if a user does not have
administrative privileges on the 3WXM host. This
issue involves the Java Virtual Machine (JVM) that is
being used by 3WXM and should be resolved with a
future release of JVM.
To use 3WXM, users must belong to a “Power Users”
group or be added to the administrators group in the
Windows operating system.
Default RADIUS parameters are not used for
configuring a specific RADIUS server. (12301)
In the CLI, RADIUS parameters are implicitly inherited
from the default set of RADIUS parameters. In
3WXM, a RADIUS server’s initial parameters are
always set to the factory default, regardless of any
changes made to the Default RADIUS Parameters
Setup page.
Set all RADIUS server parameters directly. You can use
a domain policy to configure all the RADIUS servers
and server groups for all the WX switches in the
Mobility Domain.
Using the Undo feature in the Local & Network
Changes dialog box does not restore a WX switch to
its original Mobility Domain. (12676)
If you move a WX switch from one Mobility Domain
to another, the WX switch is not moved back to the
original Mobility Domain when you use the Undo fea-
ture.
Manually move the WX switch back to the original
Mobility Domain.
When the VLAN name is composed entirely of
numbers in ACL VLAN mappings imported from the
CLI, 3WXM assumes that the VLAN name is a VLAN
ID. (12682)
A VLAN can be specified in the CLI by its VLAN ID or
its VLAN name. When the CLI command is imported
into 3WXM, the VLAN reference type is not apparent.
If the VLAN reference is composed entirely of num-

Known Problems 5
bers, 3WXM assumes that the reference is a VLAN ID.
Otherwise, 3WXM assumes that the reference is a
VLAN name.
Do not use VLAN names that consist entirely of num-
bers.
Changes in the order of network or admin access
rules are not displayed in Review Changes. (14191)
Network and admin access rules are organized in
ordered lists. When changing the list order in 3WXM,
the Review Changes dialog box does not show the
new order of the access rules.
No workaround is required. This is a display anomaly
in the Review Changes dialog box. Deployment and
synchronization of ordered list changes are performed
correctly.
Importing of a floor plan in JPEG format might fail
with a color conversion exception. (14612)
On rare occasion, importing a floor plan in JPEG
format might fail with the following Java exception:
sun.awt.image.ImageFormatException: Unsupported
color conversion request.
This exception occurs because of unusual color pal-
ette settings in the file.
Using a JPEG editing tool, manually remove all extra-
neous information possible to remove the problem-
atic color information. Alternatively, convert the JPEG
file into a GIF file to import.
Size or location adjustments of shared coverage
areas with identical dimensions might cause
problems when you run Compute and Place. (14631)
When shared 802.11a and 802.11b/g coverage areas
are created, one coverage area is directly placed on
top of the other. If you resize or move one of the cov-
erage areas, the other coverage area is now a differ-
ent shape or in a different location. Running
Compute and Place might not work.
Use the dimension toolbar icon to set the center and
size of each coverage area to identically match each
other.
When importing a CAD file (DWG/DXF), any lines
with arrowheads will display incorrectly. (15906)
When importing DXF or DWG CAD files with lines
that have line ends (arrows, dots, and so on) the
objects get imported with huge arrows at the ends of
the lines.
Use a CAD program to remove any arrowheaded
lines, or modify the line’s properties to not display an
arrowhead. Alternatively, delete the line while in the
Edit Content page of the Floor wizard in 3WXM.
3WXM cannot undo or redo object additions or
deletions. (15910)
Undo and redo operations are currently supported for
drawing object modifications, only. If a drawing
object is delete or created, this operation cannot be
undone, even though the “Undo” icon appears to be
active.

6WIRELESS LAN SWITCH MANAGER (3WXM) VERSION 3.0 RELEASE NOTES
There is no current workaround. If you perform an
“Undo” in this situation, you will undo the last sup-
ported action, instead.
3WXM incorrectly reports Mobility Domain
configuration changes after deleting and
re-uploading a WX switch. (16044)
If you delete a WX switch and re-upload the same
switch, Review Local Changes erroneously reports
that the seed and member switches need to be
deployed. This may be confusing as the configuration
to be deployed is identical to the current configura-
tion.
No action is required. Deploy the indicated configura-
tions to the WX switches.
3WXM reports that changes have occurred even
when the changes cancel each other out, but does
not list the changes. (16212)
If you make a configuration change to a WX switch
and then reverse the change before synchronizing
3WXM and the WX, 3WXM still reports that changes
have occurred, but does not list any changes. For
example, if you use the CLI to change the system
description, then clear the change, the Local & Net-
work Changes dialog shows Configuration changes
in the Local Status field for the WX. However, no
changes are listed when you select Review.
This issue is cosmetic and does not affect the configu-
ration or operation of 3WXM or the switches.
Domain Policy manager does not correctly identify
changes. (16383,16384,17692)
The Domain Policy manager does not list some
changes, such as changes to the order of network
access rules. Generally, changes are not listed if there
is no valid CLI to generate for the configured values.
For example, if you configure an 802.1X network
access rule but you do not specify a RADIUS server
group, this is an invalid configuration and cannot be
mapped to a valid CLI command.
3WXM does not support the Ctrl + drag-and-drop
mouse operation. (16425)
Polling interval for client session cannot be changed.
(17585)
By default, 3WXM polls every 10 seconds for updates
to information for clients on the watch list. In Version
3.0, this polling interval cannot be modified.
Enabling STP on an WX switch's management VLAN
causes a configuration deployment to fail. (17668)
If you use 3WXM to enable STP on an WX switch's
management VLAN, then deploy the configuration,
the deploy fails. The failure occurs because the man-
agement interface must pass through the standard
Listening and Learning states, which together take at
least 30 seconds, before the interface can change to
the Forwarding state. Until the interface reaches the
Forwarding state, the switch cannot receive traffic,
such as configuration deployment from 3WXM, on its
management interface.

Known Problems 7
If this occurs, wait 30 seconds for the interface to
reach the Forwarding state, then accept the WX
switch's change in 3WXM.
Extended character sets not supported in CAD files.
(17778)
3WXM does not support characters that are
non-ASCII or not in the U.S. character set for plan
names or for text strings within CAD files (DXF or
DWG format). If such characters are used, they might
not be displayed properly in 3WXM.
Use only ASCII, U.S. characters in CAD files.
Changing the unit of measurement of a drawing
requires rescaling the drawing. (17941)
If you change the unit of measurement for a floor
plan, 3WXM does not rescale the drawing accord-
ingly. For example, if you change the unit of measure-
ment from feet to meters, a 1-foot distance becomes
a 1-meter distance.
If you change the unit of measurement, use the ruler
icon to adjust the scale of the floor plan.
When calculating MAP placement, selection of
coverage vs capacity affects both areas in a shared
area. (17982)
When configuring options for calculating MAP place-
ment, the setting of the Use Capacity Calculation
option affects both areas of a shared area.
Upgrade requires complete uninstall of Beta version
first. (18144)
Before you upgrade from a Beta version, you must
uninstall it first, including the option to delete the
network plans. If you install 3WXM without uninstall-
ing the Beta version first, the monitoring service will
not start properly. To upgrade:
1Save a copy of your network plans. The plans are
located in the Wireless Switch Manager\xml\db folder
where you installed 3WXM.
2Start the uninstall program.
3Leave the option to delete network plans selected.
4Do not select the option to delete the serial number.
5Install Version 3.0.
6Copy your network plans back into Wireless Switch
Manager\xml\db.
If you do accidentally upgrade without uninstalling
the previous version, do the following:
1Stop the monitoring service.
2Delete all files from the Wireless Switch Manager\ser-
vices-db\data folder.
3Restart the monitoring service.
Disabled radio on operational MAP does not turn red
if the MAP or WX switch becomes unavailable.
(18330)
In the Explore and Status Summary windows of the
Monitor tab, the operational state of the equipment
is indicated by color, and is also indicated in the Status

8WIRELESS LAN SWITCH MANAGER (3WXM) VERSION 3.0 RELEASE NOTES
column of the Status Summary window. For example,
if a WX switch goes down, its icon turns red. How-
ever, if the MAP or WX switch for a disabled radio
goes down, the radio does not turn red. In addition,
the value in the Status column of the Status Summary
window changes from Operational to Not Applicable.
(It is normal for a disabled radio’s state to be Opera-
tional, since disabled radios perform RF sweeps for
rogue detection.)
This issue is cosmetic only and does not affect other
information displayed for the equipment.
Channel and power assignment use only default
channel and power settings for third-party APs.
(18346)
If you use third-party APs in a coverage area, the
Compute Optimal Power option assigns the default
power setting to the third-party APs. Likewise, the
Assign Channels to MAPs option assigns the default
channel numbers to the third-party APs.
Use coverage visualization to see the coverage, manu-
ally adjust the power and channel assignments for the
third-party APs, then lock the APs in place and use
the Compute and Place, Compute Optimal Power,
and Assign Channels to MAPs options again.
Image files are left over in nonvolatile storage when
a switch is upgraded using 3WXM. (18349)
When you upgrade a WX switch with 3WXM, 3WXM
copies the new image file into the user files area of
nonvolatile storage. The switch then copies the image
file from the user files area into a boot partition. How-
ever, the unneeded copy of the image file in the user
files area is not deleted. The user files area can
become full after as few as three upgrades, making
further upgrades impossible until the superfluous
image files are deleted. This issue does not occur of
you use the CLI to perform the upgrade.
After an upgrade, use the CLI to delete the unneeded
copies of the image files from the user files area. (Use
the dir command to display the file names, then use
the del command to remove the files.)
