The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

          -- This data type specifies 1 nanosecond units as
          -- an integer value.
          --
          -- NOTE: The encoding is normal integer representation, not
          -- two's complement.  Since this type is used for variables
          -- which are encoded as TimerTwosComplement in the ANSI
          -- specification, two operations need to be performed on such
          -- variables to convert from ANSI form to SNMP form:
          --
          -- 1) Convert from two's complement to normal integer
          --    representation
          -- 2) Multiply by 80 to convert from 80 nsec to 1 nsec units
          --
          -- No resolution is lost.  Moreover, the objects for which
          -- this data type is used effectively do not lose any range
          -- due to the lower maximum value since they do not require
          -- the full range.
          --
          -- Example: If fddimibMACTReq had a value of 8 ms, it would
          -- be stored in ANSI TimerTwosComplement format as 0xFFFE7960
          -- [8 ms is 100000 in 80 nsec units, which is then converted
          -- to two's complement] but be reported as 8000000 in SNMP
          -- since it is encoded here as FddiTimeNano.

          -- This data type is used to refer to an instance of a  MAC,
          -- PORT, or PATH Resource ID.  Indexing begins

          -- string of 8 octets, represented as X' yy yy xx xx xx xx
          -- xx xx' with the low order 6 octet (xx) from a unique IEEE
          -- assigned address.  The high order two bits of the IEEE
          -- address, the group address bit and the administration bit
          -- (Universal/Local) bit should both be zero.  The first two
          -- octets, the yy octets, are implementor-defined.

          -- is in the IEEE (ANSI/IEEE P802.1A) canonical notation for
          -- 48 bit addresses.  The canonical form is a 6-octet string
          -- where the first octet contains the first 8 bits of the
          -- address, with the I/G(Individual/Group) address bit as the
          -- least significant bit and the  U/L (Universal/Local) bit
          -- as the next more significant bit, and so on.  Note that
          -- addresses in the ANSI FDDI standard SMT frames are
          -- represented in FDDI MAC order.

          FddiMACLongAddressType ::= OCTET STRING (SIZE (6))
          -- The representation of long MAC addresses as management
          -- values is in the IEEE (ANSI/IEEE P802.1A) canonical
          -- notation for 48 bit addresses.  The canonical form is a

          -- (Universal/Local) bit as the next more significant bit,

          -- These timers, when stored in a Spanning Tree Protocol's
          -- BPDU, are in units of 1/256 seconds.  Note, however,
          -- that 802.1D-1990 specifies a settable granularity of
          -- no more than 1 second for these timers.  To avoid
          -- ambiguity, a data type is defined here as a textual
