ENTERASYS-UPN-TC-MIB device MIB details by Enterasys Networks


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.

                     StationAddress object is a zero-length string.

         dns(16)     A DNS domain name as defined by the
                     InetAddressDNS textual convention as defined
                     in RFC3291.
         Each definition of a concrete StationAddressType value must 
         be accompanied by a definition of a textual convention for use
         with that StationAddressType.
         The StationAddressType textual convention SHOULD NOT be 
         subtyped in object type definitions to support future extensions.
         It MAY be subtyped in compliance statements in order to require
         only a subset of these address types for a compliant
        "STD0058 (RFC2579), Textual Conventions for SMIv2.

    STATUS      current
        "Denotes a generic Internet address.

         An StationAddress value is always interpreted within the 
         context of an StationAddressType value. Every usage of the
         StationAddress textual convention is required to specify 
         the StationAddressType object which provides the context.  
         It is suggested that the StationAddressType object is 
         logically registered before the object(s) which use the 
         StationAddress textual convention if they appear in the 
         same logical row.

         The value of an StationAddress object must always be
         consistent with the value of the associated StationAddressType
         object. Attempts to set an StationAddress object to a value
         which is inconsistent with the associated StationAddressType
         must fail with an inconsistentValue error.

         When this textual convention is used as the syntax of an
         index object, there may be issues with the limit of 128
         sub-identifiers specified in SMIv2, STD 58. In this case,
         the object definition MUST include a 'SIZE' clause to
         limit the number of potential instance sub-identifiers."

          The scope identifier MUST disambiguate identical address
