RFC1304-MIB device MIB details by RFC

RFC1304-MIB file content

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.

       Format Error.

       - Invalid BAsize Field Value,

       An error is considered to have occurred when the
       BAsize field of an SIP L3PDU contains a value less
       that 32, greater than 9220 octets without the
       CRC32 field present, greater than 9224 octets with
       the CRC32 field present, or not equal to a
       multiple of 4 octets,

       - Invalid Header Extension Length Field Value,

       An error is considered to have occurred when the
       Header Extension Length field value is not equal
       3.

       - Invalid Header Extension - Element Length,

       An error is considered to have occurred when the
       Header Extension - Element Length is greater than
       12.

       - Invalid Header Extension - Version Element
       Position, Length, or Value,

       An error is considered to have occurred when a
       Version element with Length=3, Type=0, and Value=1
       does not appear first within the Header Extension,
       or an element Type=0 appears somewhere other than

       within the first three octets in the Header
       Extension.

       - Invalid Header Extension - Carrier Selection
       Element Position, Length, Value or Format,

       An error is considered to have occurred when a
       Carrier Selection element does not appear second
       within the Header Extension, if the Element Type
       does not equal 1, the Element Length does not
       equal 4, 6, or 8, the Element Value field is not
       four BCD encoded decimal digits used in specifying
       the Carrier Identification Code (CIC), or the
       identified CIC code is invalid.

       - Header Extension PAD Error

       An error is considered to have occurred when the
       Header Extension PAD is 9 octets in length, or if
       the Header Extension PAD is greater than zero
       octets in length and the Header Extension PAD does
       not follow all Header Extension elements or does
       not begin with at least one octet of all zeros.

       - BEtag Mismatch Error,

       An error is considered to have occurred when the
       Beginning-End Tags in the SIP L3PDU header and
       trailer are not equal.

       - BAsize Field not equal to Length Field Error,

       An error is considered to have occurred when the
       value of the BAsize Field does not equal the value
       of the Length Field.

       - Incorrect Length Error, and

       An error is considered to have occurred when the
       the Length field value is not equal to the portion
       of the SIP L3PDU which extends from the
       Destination Address field up to and including the
       CRC32 field (if present) or up to and including
       the PAD field (if the CRC32 field is not present).
       As an optional check, an error is considered to
       have occurred when the length of a partially
       received SIP L3PDU exceeds the BAsize value.


       - MRI Timeout Error.

       An error is considered to have occurred when the
       elapsed time between receipt of BOM and
       corresponding EOM exceeds the value of the MRI
       (Message Receive Interval) for a particular
       transport signal format.

       An entry is indexed by interface number and error
       type, and contains Source Address, Destination
       Address and a timestamp. All these errors are
       counted in the sipL3Errors counter.  When
       sipL3PDUErrorTimeStamp is equal to zero, the
       SipL3PDUErrorEntry does not contain any valid
       information."
