Connection to the console port is used for direct local management. The switch
console port settings are set as follows:
" Baud rate — 9600
" Data bits — 8
" Stop bit — 1
" Parity — None
" Flow control — XON/XOFF
The terminal connected to the console port on the switch must be configured with the
same settings. This procedure will be described in the documentation supplied with
the terminal.
