VersaLink Wireless Gateway (Model 7500)
14.2.4.1
LAN Devices
The following screen will appear if you select
Advanced > Diagnostics > System Status Tables > LAN Devices
from the main menu. The Gateway scans the network for devices that are connected to your LAN. If you want to
disable this feature in the Gateway, click
disable scanning
.
IP Address
Displays the IP network address that your Gateway is on.
MAC Address
Displays the Media Access Controller (MAC) address of this device.
Name
Displays the ASCII (text) name of the devices connected to the LAN.
Status
Displays the status of the devices connected to the LAN.
Enable/disable scanning
Click this button to enable or disable the scanning function.
14.2.4.2
Wireless Stations
The following screen will appear if you select
Advanced > Diagnostics > System Status Tables > Wireless
Stations
from the main menu. This screen displays the wireless devices that are connected to your LAN along with
a history of all stations that authenticated and/or associated with the AP. There is only one entry per station, and the
data shown is based on the most recent authentication or association transaction between the AP and the given
station.
Authentication is the security process by which a station is recognized and allowed to associate for the purpose of
passing data. A station must be authenticated before it can associate with an AP. A station can be authenticated by
multiple access points; however, it may be associated with only one at a time. Authentication and association are
separate processes involving separate records. A station initiates both authentication and association, and the AP
firmware completes both. The AP informs the Gateway of the processes via autonomous management messages.
During periods of heavy WLAN traffic, it is possible that management messages will be dropped in favor of data. In
such instances, it is possible for the history to show a station still associated with the AP even though the station
may have roamed to another AP or is off.
NOTE:
A Wireless device must be connected to the Gateway for this table to be populated.

Station
Displays the order number in which the stations are first accessed by Gateway. The
history allows a maximum of 250 stations.
MAC Address
Displays the Media Access Controller Address assigned to the station. This is a unique
number typed into the WLAN device’s permanent memory during production. A
station’s MAC address is typically printed on the card or can be viewed using the
card’s configuration utility.
State
Displays the current state of the negotiation between the station and Gateway.
14.2.4.3
RIP Table
The following screen will appear if you select
Advanced > Diagnostics > System Status Tables > RIP Table
from
the main menu. The RIP Table allows you to monitor network routes received via the Routing Information Protocol
(RIP).
NOTE:
RIP must be enabled for this table to be populated.
RIP Network Routing Table

that may be printed or saved to file.
Remote Logging
Enable/Disable
Click this check box to enable/disable Remote Logging. Remote Logging
contains the configuration for the diagnostics remote logging, allowing
diagnostics logs to be sent to a machine running a syslog server. If saving the
diagnostics logs is desired, remote diagnostics logging should be enabled, and
the IP address of the syslog server must be configured.
Note: The syslog server must be configured to listen on udp port 514, which is
usually the default. In order for the logs to be saved to the syslog server, the
server should be configured to save the logs to a file.
Some of the free syslog
servers available on the internet are kiwisyslog, MT_syslog and 3CSyslog.
Remote IP Address
Displays the IP address of the syslog server machine to which the diagnostics
logs will be sent.

Test Utilities
The following screen will appear if you select
Advanced > Diagnostics > Test Utilities
from the main menu. This
screen provides tools for diagnosing network connection problems. Some tests depend on the modem status and the
capabilities exercised by previous tests, and, therefore, may not be run.
If you want to PING using the
Test Utilities
screen, type your
DNS
or
IP
address in the fields provided, and click
the
test
button. The System Self Test will run a diagnostic test that executes independent of firewall security
settings.
If you want to PING using the MS-DOS (shell) window on your PC or station, you will first need to check your
firewall security setting. (If you PING via DOS shell you are susceptible to firewall rules, as this PING is dependent
on your Gateway’s firewall settings.) If your firewall is set to
Medium
or
High
, you will not be able to PING. You
must set your firewall security setting to
Low
or
None
.
•
To run a DNS test, type the appropriate host name in the field provided, and then click
test.
•
To run a PING test, type the appropriate IP address or host name in the field provided, and then click
test.
•
To run a Trace Route, type the appropriate IP address or host name in the field provided, and then click
trace.
•
To run a full diagnostic test on your Gateway, click
Test All.
DSL
Displays the DSL connection status. If the status is DOWN, check to be sure the cable connecting
your Gateway to the DSL wall jack is properly connected. (Also, ensure the plug is properly seated
in the Gateway jack.) If this is ok, then try another phone cable. Next, wait for the Gateway to train
(this may take up to two minutes). If it still hasn’t come into sync, try power cycling the Gateway. If
after trying these approaches the Gateway still will not sync, contact your ISP.
•
UP: Your Gateway is operating correctly and has obtained synchronization with the
opposing network device.
•
DOWN: Your Gateway is operating correctly, but not synchronized with the opposing
device.
