CISCO CCNA Device Basic Configuration

1. Define a host name for the router

router>enable \ \ Enter Privileged mode

Router#configure terminal \ \ Enter global configuration mode

Router (config) #hostname R1 \ \ Change the router name

R1 (config) #

The default router name is "Router", which can be used to differentiate the device from the network for easy management.

2. Turn off Domain name resolution

R1 (config) #no IP domain-lookup

By default, when an administrator enters the wrong command or the command cannot be found locally, the router triggers the Domain name resolution feature, and during domain name resolution, the administrator typically waits for the entire domain name resolution process to be completed before the command can be re-entered.

R1#pingg

Translating "Pingg" ... domain server (255.255.255.255)

You can break this domain name resolution by pressing the key combination ctrl+shift+6

3, the Console line off the line timeout.

R1 (config) #line console 0

R1 (config-line) #exec-timeout 0 0

iOS for security purposes, iOS automatically jumps from other modes when an administrator leaves the terminal for a period of time

to user mode. When the experiment is generally done, the time is changed to 0 minutes and 0 seconds, which means the shutdown timeout.

4, the Console line to open output synchronization.

R1 (config) #line console 0

R1 (config-line) #logging synchronous

When the administrator is operating on the terminal, there are usually a lot of system logs appear, these system logs

Will disrupt the configuration of the current administrator, such as:

R1 (config) #i

*mar 1 00:22:29.903:%sys-5-config_i:configured fromconsole by

Consolent f0/0

In order to prevent this interference, the output synchronization is usually turned on.

Initialization management is the basis for subsequent other experiments, no matter what the subsequent experiment, basically the above several lives

The order is "standard"
