FAST-ETHERNET-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.

SYNTAX  INTEGER  (1..1023)
ACCESS  read-only

DESCRIPTION
        "This indicates the technology ability of the local hardware.
        The value of this object is the logical OR of all supported 
        technologies.  Where each technology is given the values below:

          other(1)                      Undefined, or ability not known
          Auto-Negotiation(2)           Auto-Negotiation

          100BASE-TX(32)                100BASE-TX  
          100BASE-TXFD(64)              Full Duplex 100BASE-TX
          100BASE-T4(128)               100BASE-T4 
          100BASE-FX(256)               100BASE-FX
          100BASE-FXFD(512)             Full Duplex 100Base-FX

        For example a port which supported 100Base-TX(32), 100Base-TXFD(64),
        and Auto-Negotiation(2) would have a value of 98(32 + 64 + 2)."
::= { ctFastEthernetCtlEntry 4 }


ctFastEthernetCurrentOperationalMode OBJECT-TYPE
SYNTAX  INTEGER (1..1023)
ACCESS  read-write
STATUS  mandatory
DESCRIPTION
        "Indicates the current operational mode of this port.
        The value of this object is the logical OR of current opertational
        mode and how we arrived at that mode, whether it be by 
        Auto-Negotiation(2), Manual-Config(4) or default.
        Where each mode is given the values below:

          other(1)                      Initializing or no link, ability unknown
          Auto-Negotiation(2)           Auto-Negotiation/Parallel Detection
          Manual-Config(4)              Manually Configured
          10BASE-T(8)                   10BASE-T
          10BASE-TFD(16)                Full duplex 10BASE-T
          100BASE-TX(32)                100BASE-TX  
          100BASE-TXFD(64)              Full Duplex 100BASE-TX
          100BASE-T4(128)               100BASE-T4
          100Base-FX(256)               100Base-FX
          100Base-FXFD(512)             Full Duplex 100Base-FX

        For example, a port operating at 100Base-TX(32) achieved through 
        Auto-Negotiation(2) would have a value of 34(32 + 2).
        If the port was manually configured(4) for 100Base-TX(32) this object 
        would have a value of 36(32 + 4).

        Values written to this object are limited to values read from
        ctFastEthernetLocalTechnologyAbility, with the addition of
        Manual-Config(4) but excluding other(1).  Therefore if 
        ctFastEthernetLocalTechnologyAbility has a value of 98 writing a 
        value of 256 would result in an error.  That is to say 100Base-FX 
        is not supported on this port.

        A set to a value of Auto-Negotiation(2) will result in
        auto-negotiation being enabled and will cause link re-negotiation.
        Note: this re-negotiation will in every case cause temporary link loss 
        during the link re-negotiation. Any other set with Auto-Negotiation(2)
        included will result in an error since you can not force an operational
        mode and auto-negotiation at the same time.

        A set to a value of Manual-Config(4) will result in auto-negotiation
        being disabled but the port staying at its current operational mode
        until device reset/power down at which time the port will come up
        in default mode. A subsequent read will indicate only the current
        operational mode achieved by default means.

        A set to any other value (port is being manually configured) must
        reflect a single ability.  For example writing a value of 68 would
        result in auto-negotiation being disabled and the port being manually
        configured(4) for 100Base-TXFD(64).  However a write of 100 would
        result in an error."

ctFastEthernetAdvertisedTechnologyAbility OBJECT-TYPE
SYNTAX  INTEGER   (1..1023)
ACCESS  read-write
STATUS  mandatory
DESCRIPTION
        "Indicates the advertised ability of the local hardware, but only
        becomes active on ports that have auto-negotiation enabled.  

        For example a port which will advertise 100Base-TX(32) and
        100Base-TXFD(64) ablilities would have a value of 96(32 + 64). A port
        that does not support auto-negotiation will be read as other(1).

        Values written to this object are limited to values read from
        ctFastEthernetLocalTechnologyAbility, excluding other(1) and
        Auto-Negotiation(2).  Therefore if ctFastEthernetLocalTechnologyAbility
        has a value of 98 writing a value of 128 would result in an error.  That
        is to say 100Base-T4 is not supported on this port. Furthermore, if
        ctFastEthernetLocalTechnologyAbility has a value that does not include
        Auto-Negotiation(2), writing any value will result in an error. That is
        to say that this port does not support Auto-Negotiation and therefore
        does not support ctFastEthernetAdvertisedTechnologyAbility.

        A successful set operation will result in immediate link re-negotiation
        if ctFastEthernetCurrentOperationalMode has a value that includes 
        Auto-Negotiation(2)(meaning Auto-negotiation is enabled). 

        Note: this re-negotiation will in every case cause temporary link loss 
        during the link re-negotiation.  If set to a value that is incompatible 
        with ctFastEthernetReceivedTechnologyAbility, link negotiation will not 
        be successful and will cause permanent link loss."

DESCRIPTION

          100Base-FXFD(512)             Full Duplex 100Base-FX

        For example a port which supports 100Base-TX(32), 100Base-TXFD(64),
        would have a value of 98(32 + 64 + Auto-Negotiation(2)).

        A read should always include Auto-Negotiation(2), unless the link
        partner does not support auto-negotiation, at which time the value
        will be Not-Detected(4) or auto-negotiation is disabled(or not
        supported) for this port at which time the value will be other(1)."
