Disabling a Telnet Connection

To disable Telnet connections to the switch, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# feature telnet
switch(config)# no feature telnet

Configuring Console Port Settings

The console port is an asynchronous serial port that enables switches in the Cisco MDS 9000 Family to
be set up for initial configuration through a standard RS-232 port with an RJ-45 connector. Any device
connected to this port must be capable of asynchronous transmission. Connection to a terminal requires
a terminal emulator to be configured as 9600 baud, 8 data bits, 1 stop bit, no parity.
The console baud rate automatically reverts to the default rate (9600) after any BIOS upgrade.
Caution
To configure the console port parameters from the console terminal, follow these steps:
Command
Step 1
switch# config terminal
switch(config)#
Step 2
switch(config)# line console
switch(config-console)#
Step 3
switch(config-console)# speed 9600
Step 4
switch(config-console)# databits 8
Step 5
switch(config-console)# stopbits 1
Step 6
switch(config-console)# parity none

Verifying Console Port Settings

Use the show line console command to verify the configured console settings. This command also
displays problems that may have occurred along with the other registration statistics.

bps (110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200,
28800, 38400, 57600, 115200). The valid values for
Supervisor-2 modules are 9600, 19200, 38400, and
115200. Be sure to specify one of these exact values.
Configures the data bits for the console connection. The
default is 8 data bits and the valid range is between 5 and
8 data bits.
Configures the stop bits for the console connection. The
default is 1 stop bit and the valid values are 1 or 2 stop bits.
Configures the parity for the console connection. The
default is no parity and the valid values are even or odd
parity.
