UNIT TITLE

Design basic industrial Ethernet networks

APPLICATION

This unit describes the performance outcomes, skills and knowledge required to design basic switched Ethernet networks.

The unit of competency is applied by technicians who maintain Ethernet networks in an industrial environment, and/or design small-scale alterations/extensions to existing Ethernet networks.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

ELEMENT

Elements describe the outcome of a unit of competency.

PERFORMANCE CRITERIA

Performance criteria describe the performance needed to demonstrate achievement of the element.

1.    Use fundamental techniques in arithmetic, measurement and mensuration.

1.1.      Capture and analyse Ethernet frames

1.2.      Establish the differences between V2(Bluebook) and IEEE 802.3 frames
