Console Settings
The loader, kickstart, and system images have the following factory default console settings:
• Speed—9600 baud
• Databits—8 bits per byte
• Stopbits—1 bit
• Parity—none
These settings are stored on the switch, and all three images use the stored console settings.
To change a console setting, use the line console command in configuration mode. The following
example configures a line console and sets the options for that terminal line:
switch# configure terminal
switch(config)# line console
switch(config-console)# databits 7
switch(config-console)# exec-timeout 30
switch(config-console)# parity even
switch(config-console)# stopbits 2
You cannot change the BIOS console settings. These are the same as the default console settings.
