CISCO-ENTITY-PFE-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 Packet Forwarding Engine technology are Cisco developed 
        Network Processors, which accelerates certain features in 
        order to provide better network performance.

        An agent uses this MIB to monitor the performance history 
        on any active PFE pipeline listed in the ENTITY-MIB (RFC 2737)
        entPhysicalTable. This monitoring is via measurement periods
        of actual, 1-minute, 5-minutes and 15-minutes.

        For the 1-minute and 5-minute measurement periods, perfor-
        mance statistics are calculated and displayed based on pre-
        vious 1 minute and 5 minute respectively.

        For the 15-minute period, the performance statistics are
        accumulated in fifteen minute intervals.  At any one time, 
        an agent maintains one current (incomplete) interval and up 
        to 96 completed intervals (24 hours worth).  Fewer than 96 
        intervals of data will be available if the agent has been 
        restarted within the last 24 hours. In addition, there is a 
        rolling 24-hour total of each performance statistic.

        There is no requirement for an agent to ensure fixed rela-
        tionship between the start of a fifteen minute interval and 
        any wall clock; however some agents may align the fifteen 
        minute intervals with quarter hours."
