Console Port Settings
You can access the onboard configuration program by attaching a VT100
compatible device to the switch’s serial console port. Management access
through the console port is controlled by various parameters, including a
password, timeouts, and basic communication settings. These parameters
can be configured via the web or CLI interface.
Command Attributes
• 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: 0)
• 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: 0
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)
• Silent Time – Sets the amount of time the management console is
inaccessible after the number of unsuccessful logon attempts has been
exceeded. (Range: 0-65535; Default: 0)
• Data Bits – Sets the number of data bits per character that are
interpreted and generated by the console port. If parity is being
generated, specify 7 data bits per character. If no parity is required,
specify 8 data bits per character. (Default: 8 bits)
• Parity – Defines the generation of a parity bit. Communication
protocols provided by some terminals can require a specific parity bit
setting. Specify Even, Odd, or None. (Default: None)
• Speed – Sets the terminal line’s baud rate for transmit (to terminal) and
receive (from terminal). Set the speed to match the baud rate of the
