			Table 4-4. LAN Statistics Parameters
Parameter	Description
MAC Address	MAC address	of the local port.
Mode	Port mode is set either manually or via the auto-negotiation mode (under LAN configuration screen).
	Note: When auto-negotiation protocols do not support each other, this will degrade the connection to a half-duplex mode.
	In order to avoid this, auto-negotiation should be disabled and the ports should be configured/forced manually. Half-duplex degradation will occur also when
	auto-negotiation is enabled at one port and disabled at the opposite port.
Rate (Mbps)	Port rate is set either manually or via the auto negotiation mode.
Status	Link status:	Connected = Normal operation.
		Not connected = Ethernet Link loss
Frames Received
Correct Frames	The number of frames successfully received. When a valid connection is established the number should increase steadily.
Correct Octets	The number of octets successfully received. When a valid connection is established the number should increase steadily.
Alignment	The number of frames received that are not an integral number of octets in length (RFC 1643). All frames should end on an 8-bit boundary, but physical
Errors	problems on the network could cause the number of bits to deviate from the multiple of eight.
	Recommendations:
	Check physical connections, devices and configuration.
FCS Errors	Counts the number of frames received that do not pass the FCS check (RFC 1643). An FCS check is a mathematical way to ensure that all the frame bits are
	correct without the system having to examine each bit and compare it against the original.

Recommendations:

Check for physical problem such as hardware problem, or a bad line, or noisy environment.
