CISCO-WAN-BBIF-ATM-CONN-STAT-MIB

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.
