Entities connected to a contained entity
A chassis device may contain one or more entities. Examples of entities which can be contained within a chassis device are VLANs, cards, and virtual routers. A contained entity, such as a card, may have one or more interfaces.
A failure on the chassis device suppresses failures on entities directly connected to any of the entities contained within that chassis device. In the figure below, entity B is contained within chassis device A. A failure on chassis device A suppresses a failure on interface d on device D and interface e on device E. Both interfaces d and e are directly connected to entity B.
