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.)
