CISCO-SNMP-NOTIFICATION-EXT-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.

csneSnmpNotifyFilterTable OBJECT-TYPE
    SYNTAX      SEQUENCE OF CsneSnmpNotifyFilterEntry
    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION
        "This table contains objects which are used
         to configure notification filtering parameters
         and an entry in this table will augment the 
         corresponding base entry in snmpNotifyFilterTable.

         When the csneFilterAdminTimer defined in this table 
         expires, the entire row from the snmpNotifyFilterTable 
         and the csneNotifyFilterTable will be removed.
         Thus, the csneNotifyFilterTable will provide an
         'aging' capability to the snmpNotifyFilterTable
         entries. The 'age' of an entry will be defined in the
         csneFilterAdminTimer object.

         The snmpNotifyFilterProfileStatus is an object
         in the snmpNotifyFilterProfileTable. 
         The snmpNotifyFilterProfileTable also contains 
         the snmpNotifyFilterProfileName that is used to 
         index into the snmpNotifyFilterTable (and 
         consequently the csneNotifyFilterTable). 
         If, due to the aging mechanism, there are no 
         entries in the snmpNotifyFilterTable with an 
         index corresponding to a snmpNotifyFilterProfileName 
         say abc, then the corresponding entry in the 
         snmpNotifyFilterProfileTable for abc will have its 
         row status, snmpNotifyFilterProfileRowStatus, changed 
         to 'notReady'.

         If set to 0, it indicates that the corresponding 
         snmpNotifyFilterSubtree will remain active forever.
         This value can be set when the snmpNotifyFilterRowStatus
         is active. If this is done, the csneFilterOperTimer will
         be refreshed to take the new value set in this object.

csneFilterOperTimer OBJECT-TYPE
    SYNTAX      Unsigned32

    DESCRIPTION
        "This object specifies the time in units 
         specified in csneFilterTimerUnit for which the 
         notification specified in snmpNotifyFilterSubtree 
         to remain active within the corresponding 
         snmpNotifyFilterProfileName.

         When this value becomes 0, it indicates that the 
         corresponding row in the snmpNotifyFilterTable has 
         run through the time specified in csneFilterAdminTimer. 
         This will cause the corresponding row to be deleted from 
         the corresponding snmpNotifyFilterName. 

         If snmpNotifyFilterRowStatus is notInService, then this 
         object will not be decremented, i.e. the timer will not
         run. Once the snmpNotifyFilterRowStatus is transitioned to
         active, the timer will be refreshed with the value in
         csneFilterAdminTimer.

         Example:
         If a row indexed by snmpNotifyFilterProfileName abc and 
         snmpNotifyFilterSubtree 1.2.3.1 is created for a
         csneFilterAdminTimer value of 10 units (as specified in 
         csneFilterTimerUnit). Initially, the csneFilterAdminTimer 
         and the csneFilterOperTimer will indicate 10 units. 
         If the snmpNotifyFilterRowStatus is active, then the 
         csneFilterOperTimer will start decrementing. 
         Once the csneFilterOperTimer value reaches 0, it will 
         cause the deletion of the row indexed by 
         snmpNotifyFilterProfileName abc and 
         snmpNotifyFilterSubtree 1.2.3.1. 
         Now, if snmpNotifyFilterProfileName abc has no more 
         active rows that it indexes, then, the 
         snmpNotifyFilterProfileRowStatus for the 
         snmpNotifyFilterProfileName of abc will be 
         transitioned to notReady.
