Due to a topic conflict, the subject can only be taken by those who have not previously completed the following subjects: VIHIAV96, VIHIBA01, VIHIBB03, VIHIBB02.
The basic objective of "Administrating Computer Networks I." is to introduce the practical administration of computer networks - including network design, installation, and configuration of network devices. This subject gives the basics of "Administration Computer Networks in Practice II." (VIHIAV42) subject, thus providing adequate theoretical and practical knowledge and the way of its direct application. The students who successfully complete also the subject "Administrating Computer Networks II" acquire the knowledge and skills required for the Cisco CCNA (Cisco Certified Network Associate) certification. The certification can be obtained in authorized examination centers, independently from the University education.

6. Basic functionalities of the Networking layer, addressing the interfaces. Observing the addressing and address resolution in IPv4 and IPv6 (ARP, NDP).
a) Setting IP addresses in hosts and network device interfaces b) Observation of ARP operation c) Observation of NDP operation
7. Basic settings and operation of routers. Connecting LANs. a) Setting the default gateway b) Configuration of interfaces c) Observing traffic running between LANs
8. Designing and cabling networks, computing subnetworks, address assignment. a) Design of a small network b) Implementing the designed network
9. Control message protocol of the networking layer (ICMP). Basic troubleshooting.
a) Use of ping and traceroute commands b) Observation of ICMP packets
10. Transport layer in practice, TCP and UDP. Application layer, management of applications and services, observation of some application layer protocols and services. a) Observation of TCP and UDP communication at the user b) Observation of TCP and UDP headers and operation c) Analysis of HTTP traffic d) Analysis of DNS traffic 11. Basics of network security. Building and controlling a small network.
a) Configuration of ssh for secure access to devices b) Troubleshooting, detection, localization and correction of simpler configuration errors
12. Summarization of knowledge, Midterm test (theory).
13. Practical task.
14. Recaps.
The midterm test and the practical task are evaluated in percentage results. When the above conditions are satisfied, the grade is determined according to the mean value of the midterm test and the practical task results. The grade is calculated using the following ranges:0-49% fail (1)50-65% satisfactory (2)66-76% medium (3)77-87% good (4)88-100% excellent (5)
