RFC1318-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.

para    OBJECT IDENTIFIER ::= { transmission 34 }

-- the generic Parallel-printer-like group

-- Implementation of this group is mandatory for all
-- systems that have Parallel-printer-like hardware
-- ports supporting higher level services such as
-- character streams

paraNumber OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of ports (regardless of their current
state) in the Parallel-printer-like port table."
::= { para 1 }


-- the Parallel-printer-like Port table

paraPortTable OBJECT-TYPE
SYNTAX SEQUENCE OF ParaPortEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"A list of port entries.  The number of entries is
given by the value of paraNumber."

DESCRIPTION
"A unique value for each port.  Its value ranges
between 1 and the value of paraNumber.  By
convention and if possible, hardware port numbers
map directly to external connectors.  The value for
each port must remain constant at least from one
re-initialization of the network management agent to
the next."
