EM

The environmental monitor (EM) manages and monitors the various field-replaceable units (FRUs), including the port cards, blower assemblies, power supplies, and World Wide Name (WWN) cards. EM controls the state of the FRUs during system start-up, hot-plug sequences, and fault recovery. EM provides access to and monitors the sensor and status data from the FRUs and maintains the integrity of the system by using the environmental and power policies. EM reflects system status by way of CLI commands, system light emitting diodes (LEDs), and status and alarm messages. EM also manages some component-related data.

The fabric state synchronization framework provides facilities by which the active management module can synchronize with the standby management module, enabling the standby management module to take control of the switch nondisruptively during failures and software upgrades. These facilities include version negotiation, state information transfer, and internal synchronization functions, enabling the transition from standby to active operation.

FSS is defined both as a component and service. A component is a module in the SLX-OS, implementing a related set of functionality. A service is a collection of components grouped together to achieve a modular software architecture.

The OpenFlow agent module is responsible for mapping the OpenFlow logical view to physical hardware. Any mapping error or unsupported constructs are logged by these messages.

OFMM

OpenFlow manager messages indicate any error in the flow, group, meter mod processing by the OpenFlow subsystem. These include protocol error and VDX pipeline limitations along with the internal error conditions. OpenFlow protocol exchanges and connections are also logged through this module.
