CISCO-IF-EXTENSION-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.

    DESCRIPTION
        "This textual convention defines the 'ifIndex' for a 
         set of 64 interfaces in a module.

         Each 4 bytes within the value of an object of this type
         is combined together to represent the interface index of
         a particular port in the module (i.e., each 4 byte group 
         represents the 'ifIndex' of an interface).

         The first 4 bytes (byte 1, byte 2, byte 3 and byte 4)
         combined represent the 'ifIndex' of an interface.
         While the second 4 bytes (byte 5, byte 6, byte 7 and byte 8)
         represent the 'ifIndex' for the next interface in the module,
         and so on.

         If there are only 'n' interfaces in a set of 64 interfaces in 
         the module, then bytes after the '4n' byte in this object 
         are irrelevant."

    DESCRIPTION
        "This textual convention defines the operational mode for a
         set of 64 interfaces in a module.

         The operational mode of an interface is represented by the
         value defined in the textual convention 'InterfaceOperMode'
         (defined in CISCO-ST-TC).

         Each 'byte' within the value of an object of this type,
         specifies the operational mode of an interface in the module.

         The first byte (byte 1) represents the operational mode of an
         interface in the module, whose 'ifIndex' is represented by
         the corresponding instance of 'cieInterfacesIndex'
         object in its first 4 bytes.

         The second byte (byte 2) represents the operational mode of
         an interface in the module, whose 'ifIndex' is represented by
         the corresponding instance of 'cieInterfacesIndex'
         object in its second 4 bytes.

         If there are only 'n' interfaces in a set of 64 interfaces in 
         the module, then bytes after the 'n' byte in this object 
         are irrelevant."

    DESCRIPTION
        "This textual convention defines the operational status cause

         The operational status cause of an interface is represented
         by the value defined in the textual convention
         'IfOperStatusReason' (defined in CISCO-TC).

         Each 2 bytes within the value of an object of this type is
         combined together to represent the operational status cause 
         of a particular interface in the module (i.e., each 2 byte 
         group represents the 'cieIfOperStatusCause' of an interface).

         The first 2 bytes (byte 1 and byte 2) of this object,
         represents the operational status cause of an interface 
         in the module, whose 'ifIndex' is represented by the
         corresponding instance of 'cieInterfacesIndex' object
         in its first 4 bytes.

         The next 2 bytes (byte 3 and byte 4) of this object,

         in the module, whose 'ifIndex' is represented by the
         corresponding instance of 'cieInterfacesIndex' object
         in the next 4 bytes respectively.
