Use the get command to copy the desired files to your local system. Use the quit command to exit passive FTP. Understanding the ENTITY-MIB and Extensions The ENTITY-MIB provides basic management and identification of physical and logical entities within a network switch. Cisco NX-OS support for the ENTITY-MIB focuses on the physical entities within a switch. This MIB provides details on each module, power supply, and fan tray within a switch chassis. It gives enough information to correctly map the containment of these entities within the switch. Cisco has developed a number of private extensions to the ENTITY-MIB to provide more details for these physical entities. Each MIB extensions shares the common index value, entPhysicalIndex, which allows the management application developer to link information across multiple MIBs. Table 2 lists the Cisco MIB extensions that are linked to the ENTITY-MIB by entPhysical Index. Table 2 ENTITY-MIB Extensions MIB Description CISCO-ENTITY-EXT-MIB Extends the entityPhysicalTable for modules with processors. For each of these modules, this MIB provides memory statistics and LED information. CISCO-ENTITY-FRU-CONTROL- Manages field-replaceable units, such as power supplies, MIB fans, and modules. CISCO-ENTITY-SENSOR-MIB Provides sensor data for environmental monitors such as temperature gauges. CISCO-IMAGE-UPGRADE-MIB Provides module image management based on entPhysicalIndex.
