If you are unsure contact your instructor.Īnswers Note : Refer to the Answers Lab Manual for the procedures to initialize and reload devices. Note : Ensure that the routers and switches have been erased and have no startup configurations. Refer to the Router Interface Summary T able at the end of the lab for the correct interface identifiers. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in th e labs. Other routers, switches, and Cisco IOS versions can be used. The switches used in the labs are Cisco Catalyst 2960s with Cisco IOS Release 1 5.2(2) (lanbasek9 image). Note : The router s used with CCNA hands-on lab s are Cisco 4221 with Cisco IOS XE Release 1 6.9. You will document your findings in a network topology diagram. In this lab, you must document the ports that are connected to other switches using CDP and LLDP. NTP is extremely efficient no more than one packet per minute is necessary to synchronize two machines to within a millisecond of each other. It then distributes this time across the network. By default, NTP communications use Coordinated Universal Time (UTC).Īn NTP server usually receives its time from an authoritative time source, such as an atomic clock attached to a time server. NTP uses the User Datagram Protocol (UDP) as its transport protocol.

Network Time Protocol (NTP) synchronizes the time of day among a set of distributed time servers and clients. The network devices advertise information, such as their identities and capabilities to their neighbors. It is mainly used with network devices in the local area network (LAN). Link Layer Discovery Protocol (LLDP) is vendor-neutral protocol using on the data link layer for network discovery. It can share information such as device names and IOS versions with other physically connected Cisco devices. Part 4: Configure and Verify NTP Background / ScenarioĬisco Discovery Protocol (CDP) is a Cisco proprietary protocol for network discovery on the data link layer.
