CONFIGURING SYSTEM OPTIONS AND INFORMATION

Administrative Session

TIMEOUT VALUE

Allows you to terminate login sessions after the configured “time-out value” length in time. If “0” is entered, the value will be disabled. The time-out will be enabled by entering a number greater than 0. The range is from 0 to 1,440 minutes.

NUMBER OF SESSIONS

This value disables, or limits the number of Telnet administrative sessions allowed. The default value and the maximum value is 3. If 0 is entered, the Telnet server will be disabled.

TELNET SERVER TCP PORT NUMBER

The port number of the Telnet Server TCP Port. The default value is 23.

EMERGENCY TELNET SERVER TCP PORT NUMBER

The port number for emergency Telnet sessions. The default for this emergency port is 9000.

ADMINISTRATIVE SESSION BACKGROUND INFORMATION

ALTERNATIVE DATABASE LOCATION BACKGROUND INFORMATION

In addition to using the local password file to validate a remote device who wishes to login to the CyberSWITCH, you may also choose to use an off-node database server such as TACACS or ACE. Using the off-node server allows you to share the password file on the database server for multiple systems. It may also provide more secure access to the CyberSWITCH: some of the platforms are PCs, and files on those platforms could be changed, while the database server can be physically more secure.

As an alternative to the local password file, the user can now use security token cards along with the TACACS or the ACE server, which provide the use of dynamic, one-time password capability.

SESSION INACTIVITY BACKGROUND INFORMATION

This option may be set to terminate login sessions after a configured inactivity timeout period. Since there are only a limited number of sessions available, this avoids the problem of administrator lockout because a user forgets to logout from the system.

NUMBER OF ADMINISTRATIVE TELNET SESSIONS BACKGROUND INFORMATION

Whenever IP routing is enabled, three Telnet sessions are available for system administration. Telnet access is a very useful method to manage the CyberSWITCH remotely, but there may be a case where it is desirable to disable the Telnet access for security reasons. With this configuration option, Telnet access to the system can be disabled, or the number of Telnet sessions can be limited to less than 3.

TELNET SERVER TCP PORT NUMBER BACKGROUND INFORMATION

TCP stands for Transmission Control Protocol, which uses IP to deliver its packets. The default value for this port is 23. However, if you choose to use a different port number, you may adjust this value through CFGEDIT. The Client must be aware of the port number you have configured.
