CISCO-WAN-BBIF-ATM-CONN-STAT-MIB device MIB details by Stratacom

CISCO-WAN-BBIF-ATM-CONN-STAT-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 MIB module contains ATM Connection related
        real time statistical counter objects. The ATM
        connections are applicable to PXM1 service module.
        in MGX82xx products.

        Logical Channel refers to ATM Connection(or connection
        end point).

        Terminologies used:
            broadband interface - Logical port on PXM1.
            SCR  - Sustained Cell Rate
            BT   - Burst Tolerance
            PCR  - Peak Cell Rate
            CDVT - Cell Delay Transfer Variance Tolerance
	    GCRA - The Generic Cell Rate Algorithm(GCRA) is used to
	           define comformance with repect to the traffic
	           contract. For each cell arrival, the GCRA determines
		   whether the cell conforms to the traffic contract
		   of the connection.

            GCRA1 - GCRA  Bucket 1. For CBR and UBR connections, only
                    GCRA-1 is needed to check for PCR, CDVT Conformance.

            GCRA2 - GCRA  Bucket 2. For VBR and ABR Connections, GCRA-1
                    is needed to check for PCR, CDVT conformance and
                    GCRA-2 for SCR, BT Conformance.

            EFCI - Explicit Forward Congestion Indication.
            QE    - Queue Engine(QE).
                    This ASIC Provides the traffic management functions
                    related to VC queues, QoS queues and interface
                    queues. This management function is performed
                    for both directions of traffic(ingress, egress).
            ingress - ingress traffic is defined as data flowing
                      toward the switch fabric. Ingress data can come
                      from either the Service Modules through the 
                      backplane or the PXM1 Uplink back card.
            egress  - Egress traffic is defined as data flowing
                      away from the switch fabric."
