Linux systems Configure switches through COM ports

1, the Linux server configuration switch environment

A, remotely connect to a Linux server over a network or use a Linux server locally, connect a Linux server's COM port to the console port of the switch, and install the Minicom software configuration switch on a Linux server.

b, if the minicom is not installed, the Yum installation method is as follows:

Yum install-y minicom installs COM serial communication tools, similar to the Windows system HyperTerminal.

The installation is complete and configuration is required to use minicom to configure the switch via COM port;

2. Configure minicom Software

A, before the configuration check

[[Email protected]_server ~]# ll/dev/ttys* display serial full path

CRW-RW----1 root dialout 4, Jul 2717:56/DEV/TTYS0

CRW-RW----1 root dialout 4, 2701:10/dev/ttys1

CRW-RW----1 root dialout 4, 01:10/dev/ttys2

CRW-RW----1 root dialout 4, 2701:10/dev/ttys3 Jul

[[Email protected]_server ~]# dmesg | grepttys* perform this command check

console [TTY0] enabled

Serial8250:ttys0 at I/o 0x3f8 (IRQ = 4) is a 16550A check to linux COM 0 port to recognize that the console line is connected

00:03:ttys0 at I/o 0x3f8 (IRQ = 4) is a16550a

B, minicom configuration as follows

Execute command:minicom–s Edit the serial communication tool so that Linux can configure the switch via COM port
