Cannot Telnet To Wag; Multiple Wags Have Same Ip Address - Siemens A53457 Installation & Maintenance

TROUBLESHOOTING
4.7

CANNOT TELNET TO WAG

The WAG ships from Siemens Industry, Inc. with TCP Slot #1 configured for well-known TCP port
number 23, the Internet Telnet port number. Any of the TCP slots can be configured with well-
known port number 23 and the user can Telnet to the WAG.
If the user cannot Telnet into the WAG, the most likely problem is that none of the four TCP slot
numbers is configured for port number 23. In this case, simply verify the configured port numbers
and make one of them 23. Another common problem that should be checked is the Telnet port
number being used by the Telnet Client. If the WAG is configured to listen on port 23 for Telnet
connections, make sure that your Telnet Client is attempting to establish a connection to port 23.
If one of the slots is configured for port 23 and your Telnet Client is also configured to establish a
connection to port 23 yet the user still cannot Telnet to the unit, there may be a basic Ethernet
connectivity problem to the WAG. Open a DOS window on a computer that is also connected to
the same Ethernet LAN that the WAG is connected to.
Before pinging WAG, verify that the computer subnet address matches that of
the WAG.
Perform a PING command. If PING does not get any responses, there is a bad Ethernet cable, a
bad Ethernet connection, or perhaps a bad Ethernet radio, switch, hub, or router -- or possibly a
firewall is interfering. Evaluate those possibilities and make corrections.
If PING is not successful and the LAN looks good, isolate the problem by simplifying the Ethernet
connection, if possible, to eliminate network faults.
If PING successfully returns responses, and if any of the TCP slots is configured for port 23, and
Telnet still does not work properly, try a different computer or a different Telnet client.
If the problem persists, send the WAG in for repair.

MULTIPLE WAGS HAVE SAME IP ADDRESS

Each WAG must have a unique IP address. If 2 or more units share the same IP address, the user
can see intermittent problems or a total failure in communications.
In the event that the WAG detects another device is using its configured IP address, the following
message will be displayed out the serial interface and an entry is placed into the system event log:
ERROR: WAG's IP address XX.XX.XX.XX is already in use!
