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
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.
