Configuring basic system information

In this recipe, we will outline how we can configure basic system parameters on Cisco IOS devices, such as setting the hostname, DNS server, and NTP servers. Following the network setup that we outlined at the start of this chapter, we will configure the following information on all the Cisco IOS devices:

• DNS servers 172.20.1.250 and 172.20.1.251
• NTP server 172.20.1.17
