Errored Frames Pie chart showing the distribution of errored received and transmitted frames according to the following:

Table 7-4Errored Frames

Graph	Meaning
inDiscards	Frames received at the port but discarded for internal
	reasons
inErrors	Frames received at the port but discarded due to errors
inUnknown	Frames received at the port but discarded due to
	unknown protocols
outDiscards	Frames discarded from being transmitted from the port
	for internal reasons
outErrors	Frames discarded from being transmitted from the port
	due to errors

LANE Component	The LANE Component Statistics allow you to measure the performance of
Statistics	LAN Emulation Services and LAN Emulation Clients in the network.
	You can display statistics for the following LAN Emulation Services:
	■	LES
	■	LEC
	■	LANE User
LES Performance	The LES performance statistics see Figure 7-13, allow you to see the type
	of load that exists on the LAN Emulation Services and to use this
	information for load balancing when required.

The LES Performance Statistics are as follows:

Data History graph of transmission rate of Broadcast and Unknown data (BUS) in Emulated LAN.

Data Utilization Utilization of the transmission rate of the BUS service relative to the maximum possible.

Control Frames Pie graph of quality of LE ARPs and other LAN

Emulation control frames handled by LES.

Errored Control Frames Pie graph of errored control frames.
