DECNET-PHIV-MIB device MIB details by RFC

DECNET-PHIV-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.

PhivAddr ::= OCTET STRING (SIZE (2))
-- This data type is intended as a short word representation of
-- standard DECnet Phase IV addresses. DECnet addresses are
-- hierarchically structured numbers assigned to a particular
-- DECnet node. The address is structured so that the area

     Data link overhead (except for the constant value of
     6). There is one buffer size for all circuits.

     NOTE: The BUFFER SIZE defines the maximum size messages
     that the Routing layer can forward. The SEGMENT BUFFER
     SIZE (defined below) defines the maximum size messages
     that the End Communication layer can transmit or

    a packet that has traversed too many nodes. For correct
    operation, this parameter must not be less than the
    maximum path length of the network. (The maximum path
    length is the routing distance between the two nodes of

    On adjacencies over a circuit of type

    this variable is the state of the Ethernet
    Initialization Layer for this adjacency, and can have
    values INITIALIZING or UP. (See Section 9.1.1 of
    DECnet Phase IV Routing Layer Functional Specification.)

    On adjacencies over a circuit of type
    (phivCircuitCommonType) Ethernet, CI, or FDDI, with an
    adjacent node of type (phivAdjNodeType) NONROUTING IV,
    this variable will always take on the value UP.

    On adjacencies over a circuit of type

    the state of the Routing Layer Initialization Circuit
    State. (See section 7.3, ibid.)  It can have values
    between RUN and HALT.

    On adjacencies over a circuit of type
    (phivCircuitCommonType) OTHER, this variable may be
