Table 6-14. Frame Relay Performance Statistics (2 of 2)
Statistic What It Indicates
Frame Relay Errors
(cont’d)
Unknown Error The number of frames received over the interface that do not
fall into one of the other statistic categories.
Indicates that the error is not one that the unit can recognize.
Frame Relay LMI
LMI Protocol The LMI protocol configured for the frame relay link.
Normal condition.
Status Msg Received The number of LMI status messages received over the
interface.
Normal condition.
Total LMI Errors The number of LMI errors. Reliability errors, protocol errors,
unknown report types, unknown information elements, and
sequence errors are included in this total.
Network problems.
Number of Inactives The number of times the LMI has declared the frame relay link
Inactive.
Network problems.
Frame Relay HDLC Errors
Rx Total Errors The number of receiver errors on the interface. The following
are included in this count:
H Receive invalid frames (short frames, long frames, invalid
DLCIs, unknown DLCIs, and unknown errors)
H Rx Total Discards
H Receive errors (non-octet aligned frames, frames with CRC
errors, and Rx Overruns)
Rx Total Discards The number of receiver discards on the interface. The
following are included in this count:
H Resource errors
H Rx Overruns
H Frames received when the link was down
H Inactive and disconnected DLCIs
H Inactive destination DLCIs
H Unknown EDLCIs
Rx CRC Errors The number of received CRC (cycle redundancy check) errors.
Tx Total Errors The total number of transmit errors on the interface, including
transmits discards and transmit overruns.
Tx Total Discards The total number of transmit discards on the interface,
including underrun flushes.
