Statistic

What It Indicates

 

 

Frame Relay HDLC Errors

 

 

Rx Total Errors

he number of receiver errors on the interface. The following are

 

included in this count:

 

Receive invalid frames (short frames, long frames, invalid

 

DLCIs, unknown DLCIs, and unknown errors)

 

Rx Total Discards

 

Receive errors (non-octet aligned frames, frames with CRC

 

errors, and Rx Overruns)

 

 

Rx Total Discards

he number of receiver discards on the interface. The following

 

are included in this count:

 

Resource errors

 

Rx Overruns

 

Frames received when the link was down

 

Inactive and disconnected DLCIs

 

TInactive destination DLCIs

 

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.
