CTRON-RATE-POLICING-MIB device MIB details by Enterasys Networks Inc

CTRON-RATE-POLICING-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
        "The Enterasys Rate Policing MIB module allows the user to
        set maximum ingress rates on a per port, per priority basis."
    
    REVISION    "200304101518Z"  -- Thu Apr 10 15:18 GMT 2003
    DESCRIPTION "Added display hint to CtPriList."

    REVISION    "200303111553Z"  -- Tue Mar 11 15:53 GMT 2003
    DESCRIPTION "Changed the definitions of the CtRatePolActionList and
                 CtRatePolDirectionList textual conventions.  The syntax
                 was also changed from Integer32 to INTEGER with
                 enumeration values that map to the prior bit positions."

    REVISION    "200011281551Z"  
    DESCRIPTION "Changed the CONTACT-INFO portion of the MODULE-IDENTITY
                 to reflect the company name change to Enterasys Networks.
                 Added ranges to the ctRatePolicingThreshHoldMin and 
                 ctRatePolicingThreshHold leaves."

-- Textual Conventions

CtPriList ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "x"
    STATUS      current
    DESCRIPTION
        "The least significant octet within this integer specifies
        a set of eight priorities.  Within this octet, the most
        significant bit represents the highest priority(7), and
        the least significant bit represents the lowest priority(0).
        Thus, each priority is represented by a single bit within
        the value of this object.  If that bit has a value of '1'
        then that priority is included in the set of priorities; the
        priority is not included if its bit has a value of '0'."
    SYNTAX      INTEGER (0..255) 

CtRatePolActionList ::= TEXTUAL-CONVENTION
    STATUS      current
    DESCRIPTION

        enable(1),
        disable(2)
    }
    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
        "Allows the rate policing feature to be globally
        enabled/disabled.  A value of disable(2), functionally
        supersedes the ctRatePolicingRuleStatus of individual
        entries in the ctRatePolicingConfigTable, but does not
        change their actual values."
    DEFVAL { disable }
    ::= { ctRatePolicingObjects 1}

ctRatePolicingConfigLastChange OBJECT-TYPE
    SYNTAX      TimeTicks
    MAX-ACCESS  read-only

    DESCRIPTION

ctRatePolicingConfigTable  OBJECT-TYPE
    SYNTAX      SEQUENCE OF CtRatePolicingConfigEntry
    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION
        "This table allows configuration of rate policing rules
        on this device.  Their are a limited number of resources
        available for rate policing, and this directly limits the
        number of rate policing rules that may be configured on
        each port.  As a result this table does not support dynamic
        row creation, rather, all possible rows exist in either an
        active or disabled state.  A manager application should not,
        however, infer that this configuration is necessarily fixed
        during the lifetime of the managed entity.  The allocation
        of resources could theoretically be shifted.  For example
        port 20 could have 3 resources and at some point suddenly
        have 4 or 2.  Any such change would of course cause the
        value of ctRatePolicingConfigLastChange to change.  At this
        time their is no defined mechanism to move these resources
        and there very likely never will be.  This is merely a
        warning that manager applications should not count on this."

        exceeded.  This value must be a valid action as specified
        by the corresponding ctRatePolicingActionsAllowed object.
        Also, no more than one action may be specified.  Attempts
        to set this value outside of the aforementioned guidelines

        the rate policing rule defined by the other leaves
