3 Configuring the Switch

CLI – Enter the IP address of the TFTP server, specify the source file on the server, set the startup file name on the switch, and then restart the switch.

Console#copy tftp startup-config

4-63

TFTP server ip address: 192.168.1.19

Source configuration file name: config-1

Startup configuration file name [] : startup \Write to FLASH Programming.

-Write to FLASH finish. Success.

Console#reload

To select another configuration file as the start-up configuration, use the boot system command and then restart the switch.

Console#config

 

Console(config)#boot system config: startup

4-67

Console(config)#exit

 

Console#reload

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)
