Telnet Settings

You can access the onboard configuration program over the network using Telnet (i.e., a virtual terminal). Management access via Telnet can be enabled/disabled and other various parameters set, including the TCP port number, timeouts, and a password. These parameters can be configured via the web or CLI interface.

Command Attributes

•Telnet Status – Enables or disables Telnet access to the switch. (Default: Enabled)

•Telnet Port Number – Sets the TCP port number for Telnet on the switch. (Default: 23)

•Login Timeout – Sets the interval that the system waits for a user to log into the CLI. If a login attempt is not detected within the timeout interval, the connection is terminated for the session. (Range: 0 - 300 seconds; Default: 300 seconds)

•Exec Timeout – Sets the interval that the system waits until user input is detected. If user input is not detected within the timeout interval, the current session is terminated. (Range: 0 - 65535 seconds; Default: 600 seconds)

•Password Threshold – Sets the password intrusion threshold, which limits the number of failed logon attempts. When the logon attempt threshold is reached, the system interface becomes silent for a specified amount of time (set by the Silent Time parameter) before allowing the next logon attempt.

(Range: 0-120; Default: 3 attempts)
