Table 7-16. Frame Relay Performance Statistics (1 of 2)
Statistic What It Indicates
Frame Relay Link
Frames Sent Number of frames sent over the frame relay interface.
Frames Received Number of frames received over the interface.
Characters Sent Number of data octets (bytes) sent over the interface.
Characters Received Number of data octets (bytes) received over the interface.
FECNs Received Number of FECNs received due to data traffic congestion in the
same direction of the frame carrying the FECN indicator.
BECNs Received Number of BECNs received due to data traffic congestion in the
opposite direction of the frame carrying the BECN indicator.
Frame Relay Errors
Total Errors Total number of frame relay errors includes short frames, long
frames, invalid DLCIs, unknown DLCIs, and unknown errors. This
number does not include LMI errors.
There may be a non-frame relay device on the other end of
the link, or the units at either the far-end or both ends of the link
may be configured incorrectly.
Invalid Rx Frames Number of invalid frames received over the interface. There is a
non-frame relay device on the other end of the link.
Short Rx Frames Number of frames received over the interface that were less than
5 octets in length. The device on the far end of the link may be
configured incorrectly.
Long Rx Frames Number of frames received over the interface that were more than
8196 octets in length. The device on the far end of the link may be
configured incorrectly.
Invalid DLCI Number of frames sent to invalid DLCIs (not 16–1007).
Unknown DLCI Number of frames received for unknown DLCIs.
Unknown Error Number of frames received that do not fall into one of the other
statistic categories. The unit cannot recognize the error.
