Statistic What It Indicates
Interface's PVC
DLCI DLCI number selected for display of the PVC statistics for a
specific DLCI.
This is a DLCI selection or entry field.
Tx/ Rx Characters Number of data octets ( 8-bit bytes) sent/received for the
selected DLCI on the interface.
Tx / Rx Frames Number of frames sent/received for the DLCI on the interface.
Tx / Rx Frames Number of frames sent/received for the DLCI on the interface
Within CIR that are within the committed information rate that had been
configured.
Tx / Rx Frames Number of frames sent/received for the DLCI on the interface
Exceed CIR that exceed the committed information rate that had been
configured.
Tx / Rx Frames Number of frames dropped for the DLCI on the interface due to
Dropped CIR enforcement or congestion control.
Tx / Rx Frames Number of frames sent/received for the DLCI on the interface
With DE that have the discard eligible bit set.
Tx BECN Frames Number of Backward-Explicit Congestion Notifications sent
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.
The access unit may have set this bit. This could occur if this
DLCI is a source DLCI on a PVC connection, and CIR is
greater than the CIR set for the destination DLCI, causing data
to be discarded.
This could also occur when the speed of the alternate
destination (backup) link is lower than the source DLCI's.
