Table 6-19. Frame Relay Performance Statistics (3 of 3)
Statistic What It Indicates
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 Overruns The number of receiver overruns (too many bits) on the
interface.
Rx Non-Octet Frames The number of non-octet frames received on the interface.
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.
Tx Underruns The number of transmitter underruns (too few bits) on the
interface.
