Method of setting time, warning information and port information for Cisco router

After we have configured the basic security password protection for the router, there are still some basic information of the router to be configured. For example, logging in to the router is the slogan information and description information of the router that users can see. The following is the setting method of time, alarm information and port information of Cisco router that I collected for you. I hope it will help you. The method of setting time, alarm information and port information for Cisco routers: 1. If we want all administrators of the company to see a warning message when logging in to the router, the command process is as follows.

Yong 1 & gt； enable

Yong 1 # meeting t

Yong 1 (configuration) # banner moth # warning! ! Don? Do not change any configuration #

Yong 1 (Configuration) # Exit

Yong 1 # exit

The next time you log in to the router and enter user mode (>), you will see the warning message set above.

2. We can also configure a description for each port to indicate the purpose of the port or the next hop (that is, where the connection goes).

Yong 1 (configuration) #? Omitted the command before entering configuration mode.

Yong 1 (configuration) # Interface Gigabit Ethernet 0/0? Enter Gigabit Ethernet 0/0 port configuration mode.

Yong 1(config-if)# describes that this port is connected to BT.

Yong 1 (configuration -if)# Exit

Yong 1 (Configuration) # Exit

Yong 1#show interface gigabitethernet 0/0? Display information of Gigabit Ethernet port 0/0.

3. Configure the local time for the router

Yong 1 # Clock Set11:00: 00 05mar2016

Yong 1 # display clock

By default, when we type the wrong command, the router will parse the wrong command into the name that needs to be parsed, which is very time-consuming. So we need to turn off command parsing.

Let's look at the state before closing: this process needs to wait for dozens of seconds.

Connect the router and computer with console cable, start the router, and connect to the console with putty. We suggest to configure the host name of the router first, so as to identify it, configure the privileged mode (enable) password and vty(telnet) password, and protect the router.

Privileged mode passwords of Cisco routers can be divided into plaintext passwords and encrypted passwords. It is recommended to configure the encryption password directly here, because you can directly see the plaintext password through the show running_configure command.

Set enable plaintext password

Router & gt enabled? User mode enters privileged mode.

Router # Configure Terminal? Enter global configuration mode from privileged mode.

Router (configuration) #hostname yong 1? The name of the router was changed to Yong 1.

Yong 1(config)# Enable password Guo Yong? Set the privileged password to Guo Yong.

Yong 1 (Configuration) # Exit? Enter the privileged view from the global configuration view.

Yong 1 # exit? Return to user mode

Yong 1 & gt；

Privileged mode plaintext password setting

Set the enable encryption password (independent of the above command)

Router & gt enabled? User mode enters privileged mode.

Router # Configure Terminal? Enter global configuration mode from privileged mode.

Router (configuration) #hostname yong 1? The name of the router was changed to Yong 1.

Yong 1(config)# Enable encryption Guo Yong? Set the privileged password to Guo Yong.

Yong 1 (Configuration) # Exit? Enter the privileged view from the global configuration view.

Yong 1 # exit? Return to user mode

Yong 1 & gt；

Privileged mode encryption password

Set vty line password (control telnet login)

Yong 1 & gt； enable

Yong 1#conf t？ Convt is the abbreviation of configuration terminal.

Yong 1 (configuration) #vty line 0-4? Encrypt vty 0-4 five lines.

Yong 1(config _ line)# Password Guo Yong? Set the telnet password to Guo Yong.

Yong 1(config _ line)# login

Yong 1(config_line)#end？ Exit port configuration mode
