	Command or Action	Purpose
Step 4
	end	Saves configuration changes.
	or	• When you issue the end command, the system prompts
	commit
		you to commit changes:
	Example:	Uncommitted changes found, commit them before
		exiting(yes/no/cancel)?
	RP/0/RSP0/CPU0:router(config)# end
		[cancel]:
	or

	RP/0/RSP0/CPU0:router(config)# commit	– Entering yes saves configuration changes to the

		running configuration file, exits the configuration
		session, and returns the router to EXEC mode.
		– Entering no exits the configuration session and
		returns the router to EXEC mode without
		committing the configuration changes.
		– Entering cancel leaves the router in the current
		configuration session without exiting or
		committing the configuration changes.
		• Use the commit command to save the configuration
		changes to the running configuration file and remain
		within the configuration session.
Step 5
	show hosts	Displays all configured name servers.
	Example:
	RP/0/RSP0/CPU0:router(config)# show hosts

Examples

In the following example, the domain name and DNS are configured:

RP/0/RSP0/CPU0:router# configure

RP/0/RSP0/CPU0:router(config)# domain name cisco.com

RP/0/RSP0/CPU0:router(config)# domain name-server 10.1.1.1

RP/0/RSP0/CPU0:router(config)# commit

RP/0/RSP0/CPU0:router(config)# end

RP/0/RSP0/CPU0:router# show hosts

Default domain is cisco.com

Name/address lookup uses domain service

Name servers: 10.1.1.1

Configuring Telnet and XML Host Services

For security, some host services are disabled by default. You can enable Host services, such as Telnet and Extensible Markup Language (XML), using the commands in this section. Enabling the Telnet server allows users to log in to the router using IPv4 Telnet clients.
