Client Troubleshooting

The following tables describe some common client problems and the recommended solutions:

Table 1: Client Cannot Connect to the Server (Incompatible Software)

Problem	A single client cannot connect to the server.
Cause	The client and server use different software versions.
Verification	Error message: Unable to talk to Agent! This message appears when the server software is an older version that does not use the RMI interface.
Verification	Error message: The Version of this Agent is not compatible! The client and server software versions are displayed with this error message.
Solution	Upgrade the client or server software so that both systems are using the same software version.

Table 2: Client Cannot Connect to the Server (Host Name)

Problem	A single client cannot connect to the server.
Cause	The client cannot resolve the server host name.
Verification	At a command prompt, attempt to ping the server by name.
Verification	Error message: Unable to logon to Agent!
Solution	One of the following: Configure the client for proper DNS or WINS resolution. Add the server to the client’s HOSTS file.
Solution	Log into the server and launch the ServerDirectory Editor. If the hostname contains underscores (_) or is greater than 15 characters, modify the Hostname value or the Agent to either: Modify the hostname, removing the underscores(_) Modify the hostname to the appropriate IP address Modify the hostname to one containing 15 characters or fewer. If none of the above issues are present, contact Tellabs TAC. (See Contacting Technical Support).

Table 3: Group of Clients Cannot Connect to the Server

Problem	A group of clients on a particular network cannot connect to the server.
Cause	The cause may be one of the following: A router is down, or not configured correctly. The DNS or WINS server for that network is missing an entry for the server. A firewall is blocking the traffic.
Verification	Attempt to ping the server by name.
Solution	One of the following: Troubleshoot a name resolution or router problem. If the name is resolved and the server responds, investigate a potential firewall issue. See "Maintaining Server Properties" or "Maintaining Client Properties" in the Tellabs 1100 Series Optical LAN Managing the PON User’s Guide.

Table 4: None of the Clients Can Connect to the Server

Problem	None of the clients can connect to the server.
Cause	The cause may be one of the following: The server or the directory server may not be running. The server Ethernet connection or router may be down.
Verification	Attempt to ping the server.
Solution	If the server responds, verify that the Panorama server and directory server are running on the server. If the server does not respond, troubleshoot the Ethernet or router problem, or restart the Panorama PON EMS services.
