Running Observer Software with the WAN Probe 33
WAN Load by DLCI
In a WAN installation, Observer’s Network Activity Display is called WAN Load by
DLCI. This mode shows critical WAN transfer rate and congestion statistics in a number
of formats. This display can show you the health of a WAN link at a glance and can warn
of impending slowdowns due to congestion or other error conditions.
The WAN Load by DLCI mode can be viewed as a dial, graph, or list display. Except for
list view, there are no setup options for WAN Load by DLCI mode. Every view includes a
dropdown box that lets you select which DLCI you want to monitor.
To activate WAN Load by DLCI, choose Statistics > WAN Load by DLCI . Press the
Play button to start the mode.
Dial View
DTE FECN under
CIR The number of packets seen on the DTE side of the link that had the
Forward Explicit Congestion Notification bit set, even though the
bandwidth usage was within the Committed Information Rate (CIR).
Normally this number should be zero. If bandwidth usage exceeds CIR,
congestion is expected.
DCE BECN
under CIR The number of packets seen on the DCE side of the link that had the
Backward Explicit Congestion Notification bit set, even though the
bandwidth usage was within the Committed Information Rate (CIR).
Normally this number should be zero. If bandwidth usage exceeds CIR,
congestion is expected.
DTE BECN
under CIR The number of packets seen on the DTE side of the link that had the
Backward Explicit Congestion Notification bit set, even though the
bandwidth usage was within the Committed Information Rate (CIR).
Normally this number should be zero. If bandwidth usage exceeds CIR,
congestion is expected.
