Objectives

This challenge involves the configuration of services on the device. The objectives of this challenge are to:

• Setup services.
• Define timestamp formats. Link
• Enable small TCP servers. Link
• Enable small UDP servers. Link

Sample

> en
# config t
(config)# service sequence-numbers
(config)# service timestamps log datetime
(config)# service timestamps log uptime
(config)# service dhcp
(config)# service finger
(config)# service tcp-small-servers
(config)# service udp-small-servers
(config)# service password-encryption
