Statistic
What It Indicates
Frame Relay Link
Frames Sent
Number of frames sent over the interface.
Frames Received
Number of frames received over the interface.
Characters Sent
Number of data octets ( 8-bit bytes) sent over the interface.
Characters Received
Number of data octets ( 8-bit bytes) received over the interface.
FECNS Received
Number of Forward-Explicit Congestion Notifications received
over the interface.
The network sends FECNS to notify users of data traffic
congestion in the same direction of the frame carrying the
FECN indicator.
BECNS Received
Number of Backward-Explicit Congestion Notifications
received over the interface.
The network sends BECNS to notify users of data traffic
congestion in the opposite direction of the frame carrying the
BECN indicator.
Frame Relay Errors
Invalid Rx Frames
Number of invalid frames received over the interface.
There is a non-frame relay device on the far-end of the circuit.
Short Rx Frames
Number of frames received over the interface that were less
than 5-octets ( five 8-bit bytes) in length.
There may be a non-frame relay device on the far-end of the
circuit.
Long Rx Frames
Number of frames received over the interface that were more
than 2048-octets in length.
The device on the far end of the circuit may be configured
incorrectly.
Invalid DLCI
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 access
unit may not match the DLCIs supplied by the service provider.
