Chapter 7: 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 device connected to
the serial port. (Range: 9600, 19200, 38400, 57600, or 115200 baud, Auto;
Default: Auto)
• Stop Bits – Sets the number of the stop bits transmitted per byte.
(Range: 1-2; Default: 1 stop bit)
• Password
1
– Specifies a password for the line connection. When a connection is
started on a line with password protection, the system prompts for the password.
If you enter the correct password, the system shows a prompt. (Default: No
password)
• Login
1
– Enables password checking at login. You can select authentication by a
single global password as configured for the Password parameter, or by
passwords set up for specific user-name accounts. (Default: Local)
1. CLI only.
