Variables that could appear in the panes below each graph include:
Variable Displayed Indication
Frames Sent above CIR Number of transmitted frames that exceeded the
contracted CIR.
Frames Sent within CIR Number of transmitted frames that complied
with CIR.
Frames Sent marked DE Transmit data on a management PVC is marked
discard eligible, so the network can discard the
lower-priority frame when there is congestion.
Frames discarded by the network Number of transmitted frames that were
dropped.
Bytes Sent above CIR Number of transmitted bytes over the contracted
CIR.
Bytes Sent within CIR Number of transmitted bytes within or under the
contracted CIR.
Bytes discarded by the network Number of transmitted bytes actually lost.
BECNs Received Backward explicit congestion notification
(BECN) has been sent by the network, warning
that outbound frames may encounter congestion
and may be dropped.
BECNs seconds Duration over which BECNs were received.
FECNs Received Forward explicit congestion notification (FECN)
has been sent by the network, warning that
inbound frames may encounter congestion and
may be dropped.
FECNs seconds Duration over which FECNs were received.
Congested seconds Duration over which BECNs and FECNs were
received.
BECNs and FECNs indicate network congestion issues. Frames marked DE
indicate that the DLCI is partly responsible for the network congestion; the DLCI
has exceeded its contracted CIR.
When congestion is detected on the network, select the Congestion button under
the menu bar to verify whether the DLCI is the cause for the problem.
See Chapter 11, Displaying System Information , for additional information on
these types of errors.
