Column	Description
DTE FECN under	The number of packets seen on the DTE side of the link that had the
CIR	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	The number of packets seen on the DCE side of the link that had the
under CIR	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.

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.
