RFC1213-MIB by vendor RFC

RFC1213-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.

            1 through 7, that this node performs transactions
            for, 2 raised to (L - 1) is added to the sum.  For
            example, a node which performs primarily routing
            functions would have a value of 4 (2^(3-1)).  In
            contrast, a node which is a host offering
            application services would have a value of 72
            (2^(4-1) + 2^(7-1)).  Note that in the context of
            the Internet suite of protocols, values should be

-- Implementation of the Address Translation group is

-- likely be excluded from MIB-III nodes.  From MIB-II and
-- onwards, each network protocol group contains its own

-- The Address Translation group contains one table which is
-- the union across all interfaces of the translation tables
-- for converting a NetworkAddress (e.g., an IP address) into
-- a subnetwork-specific address.  For lack of a better term,
-- this document refers to such a subnetwork-specific address

            The only value which may be set by a management

            appropriate for an agent to return a `badValue'
            response if a management station attempts to set
            this object to any other value.

            If a management station sets this object to the
            value deleteTCB(12), then this has the effect of
            deleting the TCB (as defined in RFC 793) of the
            corresponding connection on the managed node,
            resulting in immediate termination of the
            connection.

            segment may be sent from the managed node to the
