Abstract
V magistrskem delu preučimo in primerjamo standarde ter priporočila na področju Ethernet OAM (angl. OAM – Operation, administration and maintenance). Tehnologija Ethernet postaja vedno polj prisotna v mestnih in prostranih omrežjih, zato je pomembno, da imamo dobro definirane mehanizme za nadzor delovanja, administracijo in upravljanje Ethernet omrežij. V delu se osredotočimo predvsem na standarda IEEE 802.3ah in IEEE 802.1ag ter priporočilo ITU-T Y.1731. Posebno pozornost namenimo delovanju funkcij zapisanih v standardih/priporočilih ter protokolnim sporočilom. Za uspešno delovanje Ethernet OAM v omrežju je pomembno, da omrežne naprave poznajo delovanje Ethernet mehanizmov, ki morajo biti natančno specificirani. V delu se osredotočamo na funkcionalno testiranje funkcij, ki so definirane s standardi in priporočili. Funkcionalno testiranje izvedemo za zgoraj omenjena IEEE standarda. Postavimo testno topologijo omrežja v laboratorijskem okolju in delovanje funkcij standardov testiramo na omrežnih napravah proizvajalca Cisco. Pri testiranju podrobno spremljamo tudi protokolna sporočila, ki si jih naprave izmenjujejo. Kot rezultat testiranja potrdimo pravilno delovanje testiranjih funkcij na napravah, potek funkcionalnega testiranja tudi ustrezno dokumentiramo.

Title:Ethernet OAM testing
Abstract:
In this thesis we examine and compare standards and recommendations of Ethernet OAM (OAM – Operation, administration and maintenance). Ethernet technology is becoming more involved in metro and wide area networks. That is why operation, administration and maintenance mechanism on Ethernet layer are required. We take closer look to IEEE standard 802.3ah, IEEE standard 802.1ag and ITU-T recommendation Y.1731. We pay special attention to supported functions and protocol data unit. It is important that all network devices that take part in Ethernet OAM in network, support Ethernet OAM mechanisms as defined in standards. That brings us to the focus of this thesis, which is functional testing of functions defined in standards and recommendations. We perform functional testing of both IEEE standards mentioned above. We set up test topology of the network in the laboratory environment. Functions are implemented and tested on Cisco network devices. In testing we also follow protocol data units that devices exchange. As a result of functional testing we confirm that tested network devices support operation of selected functions as specified in standards. We also document the functional testing process.
