| UCS_NW_AV_TR_CA_CMD | Start-up is initiated by chip e.g., INIC.MOSTNetworkStartup()  | 
| UCS_NW_AV_TR_CA_RX_ACTIVITY | Chip is woken up by network activity.  | 
| UCS_NW_AV_TR_CA_NORMAL | Network is typically shutdown by an INIC.MOSTNetworkShutdown() command initiated locally or by a node positioned upstream (in the latter case, the shutdown flag indicates a Normal Shutdown).  | 
| UCS_NW_AV_TR_CA_ERR_SSO | Network is shutdown due to an error. In this case the shutdown reason was a sudden signal off. No shutdown flag is present.  | 
| UCS_NW_AV_TR_CA_ERR_CRIT_UNLOCK | Network is shutdown due to an error. In this case the shutdown reason was a critical unlock. No shutdown flag is present.  | 
| UCS_NW_AV_TR_CA_ERR_SYSTEM | Network is shutdown due to a chip or system error. Possible reasons are:  
INIC enters ForcedNA stateThe AutoShutdownDownDelay time expires after the EHC has detached.  | 
| UCS_NW_AV_TR_CA_NO_TRANSITION | No transition.  |
