2 – SNMP Overview A When an SNMP request arrives at the agent, the agent will compose a message and pass it on to Switch Management to process the message and provide a response to the agent. The agent then provides a response to the originator of the SNMP request. The SNMP agent does not have direct access to the internal database of the switch.

Section 4 MIB-II Objects This section covers the implementation details for the MIB-II on the SANbox/ SANbox2 switch. A MIB defines the properties of the managed object within the device to be managed. Every managed device keeps a database of values for each definition written in the MIB. It is not the actual database itself; it is implementation dependant. Definition of the MIB conforms to the SMI given in RFC 1155. The latest Internet MIB is given in RFC 1213, and is sometimes called MIB-
