Configuring Cisco IOS Basics
Task 2. Configuring Cisco IOS Basics
The following subsections detail the tasks required to apply a basic-running configuration to the NAS:

2.1 Configuring the Host Name, Enable Secret, and Time Stamps

2.2 Configuring Local AAA Security

2.3 Setting Up a Login Banner

2.4 Configuring the Loopback Interfaces, Ethernet Interface, and IP Route

2.5 Upgrading to a New Cisco IOS Release
Tech Tip
Periodically save the configuration by using the
copy running-config startup-config
command.
2.1 Configuring the Host Name, Enable Secret, and Time Stamps
Assign a host name to the NAS, specify an enable secret password, and turn on time stamps:

A host name allows you to distinguish between different network devices.

Enable secret passwords allow you to prevent unauthorized configuration changes.

Encrypted passwords in the configuration file adds greater security to the NAS.

Time stamps help you trace debug output for testing connections. Not knowing exactly when an
event occurs hinders you from examining background processes.
Step 1
Enter the following commands in global configuration mode:
hostname 5300-NAS
enable secret 0 yourpasswordhere
service password-encryption
service timestamps debug datetime msec
service timestamps log datetime msec
Note
The
enable password
command is an obsolete command. Do not use it.
Step 2
Log in with the enable secret password. The
show privilege
command shows the current security
privilege level.
5300-NAS#disable
5300-NAS>enable
Password:
5300-NAS#show privilege
Current privilege level is 15
5300-NAS#
