Login to the VLNC4x/VLNC6x.

From the Navigation menu, select System → Configuration → Telnet Session.

Result:

The Telnet Session Configuration window displays the current configuration.

Enter/Select the following parameters as required, then click Submit.

Parameters:

• Telnet Server Admin Mode — Administrative mode for inbound telnet sessions. Setting this value to Disable shuts down the telnet port. If the admin mode is set to Disable, then all existing telnet connections are disconnected. The default value is Enable.

• Allow New Telnet Sessions — If you set this to No, new telnet sessions will not be allowed. The factory default is Yes.

• Maximum Number of Telnet Sessions — This command specifies the maximum number of inbound Telnet connection sessions that can be established. A value of 0 indicates that no Telnet connections can be established.. The maximum is 5, which is also the factory default.

• Telnet Session Timeout (minutes) — Specifies how many minutes of inactivity should occur on a telnet session before the session is logged off. You may enter any number from 1 to 160. The factory default is 5.

Equivalent CLI commands:

• From the Privileged EXEC Mode, enter ip telnet server enable to enable Telnet sessions to the system and enable the Telnet Server Admin Mode.

• From the Line Config Mode, enter transport input telnet to regulate new incoming and outgoing Telnet sessions. If enabled, new Telnet sessions can be established until there are no more sessions available. An established session remains active until the session is ended or an abnormal network error ends the session.

  If the Telnet Server Admin Mode is disabled, Telnet sessions cannot be established, you must specify the ip telnet server enable command to enable Telnet Server Admin Mode.

• From the Privileged EXEC Mode, enter telnetcon maxsessions <value> to specify the maximum number of inbound Telnet connection sessions that can be established. A value of 0 indicates that no Telnet connections can be established.

• From the Privileged EXEC Mode, enter telnetcon timeout <value> to set the inbound Telnet connection session timeout value in minutes. A session is active as long as the session has not been idle for the value set.
