Simple Network Management Protocol

SNMP describes the Structure of network Management Information (SMI) in network devices, and the protocols for accessing (and possibly modifying) such information.
 
The key concept in SNMP is the Management Information dataBase, or MIB. This is formally described in the Abstract Syntax Notation -1 (ASN.1) specification language and its associated Basic Encoding Rules (BER).
 
SNMP is documented in various Internet RFCs: 1109, 1052, 1057, 1155, etc.
 
The MIB is defined in terms of only a few basic (or UNIVERSAL) ASN.1 object types. Some of these include:
 
OBJECT IDENTIFIER (OID)
A unique sequence of integers which specifies the object's location in a global tree structure - the MIB
OBJECT DESCRIPTOR
A unique printable string which describes the object's type
INTEGER
OCTET STRING
