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.
