How to modify the switch baud rate

Use of baud rate:

1, when using the console line to manage the switch, you need to configure the same baud rate as the switch on the management terminal to communicate properly;

2. When the switch baud rate is raised, the speed of transmitting files through the console port can be increased.

How to configure:

In global configuration mode, type the following configuration

(config) #line console 0

(config-line) #speed 115200

Check method:

In privileged mode, type the following configuration

#show Running-config | Begin line Con

----------The following is what is displayed----------

Line con 0

Speed 115200

Line vty 0 4

--The following omission--

-------------------------------------

The above information appears to indicate that the configuration is correct

Inverse operation mode:

Configure the baud rate to the default value--9600

In global configuration mode, type the following configuration

(config) #line console 0

(config-line) #speed 9600

Check method:

In privileged mode, type the following configuration

#show Running-config | Begin line Con

----------The following is what is displayed----------

Line con 0

Line vty 0 4

--The following omission--

-------------------------------------

The above information indicates that the default baud rate is not displayed because the configuration is correct.

Precautions:

1, the system will not display the default baud rate;

2, change the baud rate command can not be undone, in the global configuration mode, type the following code, the following hints:

(config) #line console 0
(config-line) #no speed 115200

----------The following is what is displayed----------

Failed to change line 0 ' s speed

------------------------------------

The above message indicates that the baud rate modification cannot be undone with the no command, and that the default value can only be explicitly specified if it is to be restored.

System version:

The above experimental part system version is Cisco:version 12.2 () SEE2
