Table 7-20. Frame Relay Performance Statistics (2 of 4)

Statistic

What It Indicates

 

 

Frame Relay Errors

 

 

 

Total Errors

The number of total frame relay errors, excluding LMI errors.

 

Short frames, long frames, invalid DLCIs, unknown DLCIs, and

 

unknown errors are included in this total.

 

Indicates that 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

The number of invalid frames received over the Network or

 

Port-1 interface.

 

There is a non-frame relay device on the other end of the link.

 

 

Short Rx Frames

The number of frames received over the Network or Port-1

 

interface that were less than 5-octets (five 8-bit bytes) in length.

 

There may be a non-frame relay device on the other end of the

 

link.

 

 

Long Rx Frames

The number of frames received over the Network or Port-1

 

interface that were more than 8192-octets in length.

 

The device on the far end of the link may be configured

 

incorrectly.

 

 

Invalid DLCI

The number of frames received over the interface that were

 

addressed to DLCIs outside the valid range; that is, a number

 

less than 16 or greater than 1007.

 

The device on the far end of the circuit may have been

 

configured incorrectly, or the DLCIs configured for the

 

FrameSaver unit may not match the DLCIs supplied by the

 

service provider.

 

 

Unknown DLCI

The number of frames received over the interface that were

 

addressed to unknown DLCIs.

 

The DLCI may not have been configured, or it has been

 

configured to be Inactive.

 

Indicates that the FrameSaver units or devices at both or either

 

end of the circuit have been configured incorrectly.

 

 

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.
