Description
This field displays the current VCI value of the VC/VP Endpoint 2.
This field displays the Service Class assigned to the PVC (defined by
the traffic descriptor).
This field displays the number of user and OAM cells transmitted
on this PVC/PVP.
This field displays the number of user cells received on this PVC/
PVP before any policing actions are taken.
This field displays the number of OAM and RM cells received on this
PVC/PVP before any policing actions are taken. This count does not
include any cells received with an OAM Cyclic Redundancy Check
(CRC)-10 error.
This field displays the number of nonconformant cells discarded on
this PVC/PVP that arrived with the CLP bit = 0.
This field displays the number of CRC errors detected.
This field displays the number of Oversized Service Data Units
(SDUs) detected.
This field indicates if the endpoint of a PVC/PVP is in an AIS State.
An AIS state occurs for an endpoint when a fault is detected such as
loss of cell delineation on the incoming interface or an AIS cell is
received from an upstream interface. When a loss of cell delineation
occurs, this endpoint generates OAM AIS cells downstream.
If the PVC is terminated at the MPI port on the cell switch, OAM RDI
cells are generated upstream. The AIS state will become inactive
(False) after a valid user cell is received at the endpoint or if no AIS
cell is received for approximately 2 seconds and cell delineation has
been achieved. Note that for PVCs that use the MPI interface, the
AIS State will track the current value of the other endpoint of the
PVC
This field Indicates if the endpoint of a PVC/PVP is in an RDI State.
An RDI state occurs when an endpoint receives an RDI cell from a
downstream ATM node. When the RDI state is entered, an AIS state
is also declared but no AIS cells are generated in response to the
RDI cell reception. The RDI state becomes inactive (False) after a
valid User cell is received or if no RDI cell is received for
approximately 2 seconds.
For PVCs that use the MPI interface, the RDI State tracks the cur-
rent value of the other endpoint of the PVC.
This field displays the number of nonconformant cells discarded on
this PVC/PVP that arrived with the CLP bit = 0 or 1.
This field displays the number of nonconformant cells with the
CLP=0 bit that had the CLP bit changed to 1 due to policing.
