Frame Relay
All counts continue to increment until the maximum value is reached (2
32
–2), then
the count starts over. The NextL
ink and PrevLink function keys only appear when
multiple frame relay links have been configured.
For FrameSaver units with an ISDN DBM:
All enabled multilink aggregate links are available for selection from the Frame
Relay Performance Statistics screen. The multilink aggregate link must be enabled
if statistics are to be collected for this frame relay link. When the frame relay link is
the multilink aggregate link, statistics for its related constituent links can be viewed.
To view the statistics for a multilink constituent link, select the ConstLinkS
tats
function key. All enabled multilink constituent links become available for selection.
Select the desired constituent link from the Multilink Constituent Link field.
The frame relay performance statistics collected for any frame relay link are
collected for multilink frame relay links, unless the link is a multilink aggregate link.
In this case, statistics for Frame Relay LMI and Frame Relay HDLC Errors are not
collected; these statistics are available for multilink constituent links only.

Statistic What It Indicates
Frame Relay Link
Frames Sent The number of frames sent over the interface.
Frames Received The number of frames received over the interface.
Characters Sent The number of data octets (bytes) sent over the interface.
Characters Received The number of data octets (bytes) received over the interface.
FECNs Received The 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 The 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.
