Frames Received with Unknown DLCIs - Number of frames received with unknown DLCIs.
Frames Received with Other Errors - Number of frames received with other errors.
LMI Frames Received - Number of LMI frames received.
Percent Receive Buffers In Use - Percentage of receive buffers currently in use.

Display/Update Frame Relay PVC Statistics
To clear the PVC statistics counters, you must enter the test number followed by the update
symbol ( 2,u ) on the Communications menu. This will enable the PF4 key to clear all counters
for the currently displayed PVC. A 584__32 event will be logged if PF4 is used to clear the
Frame Relay PVC counters.
The maximum value for all counters is 4,294,967,295. Once a counter has reached the
maximum value, it will start back at zero.
The refresh key (PF9) can be used to update the statistics for the currently displayed PVC.
The PF7 and PF8 keys can be used to display statistics for other Frame Relay PVCs.
Line - Line ID of this line.
DLCI - DLCI number shown in decimal.
Status - Current status of this PVC.
• Up indicates that this PVC is in a normal data transfer state.
• Congestion indicates that the PVC is in a data transfer state but the transmit rate has
been temporarily reduced due to congestion.
• Down indicates that this PVC has is not currently in a data transfer state. PVCs may be
“down” due to line problems, such as an unplugged cable, or network reasons such as
an inactive switch or destination FRTE.
Frames Received - Total number of frames received.
Bytes Received - Total number of bytes received.
BECNs Received - Number of frames received with the BECN bit set.
FECNs Received - Number of frames received with the FECN bit set.
Frames Transmitted Within CIR - Number of frames transmitted within the CIR.
Bytes Transmitted Within CIR - Number of bytes transmitted within the CIR.
Frames Transmitted in Excess of CIR - Number of frames transmitted above CIR but within
Excess Burst (Be).
Bytes Transmitted in Excess of CIR - Number of bytes transmitted above CIR but within
Excess Burst (Be).
Frames Transmitted after Deferral - Number of frames transmitted which were internally
deferred due to CIR constraints.
Bytes Transmitted after Deferral - Number of bytes transmitted which were internally
deferred due to CIR constraints.
Frames Dropped due to Congestion - Number of frames dropped during the transmit process
due to congestion.
