SML Example Scenarios in Normal Condition
Following are example scenarios with SML-enabled media converters.
Figure 9 shows Link LED behavior of end nodes and a media converter
with copper and fiber ports with SML enabled under normal condition.
Figure 9. SML in Normal Condition with One Media Converter
Figure 10 shows Link LED behavior of end nodes and media converters
with SML enabled under normal condition. Two media converters with
