Table 6-2. Ethernet Statistic Parameters (4-Port Ethernet Module)
Parameter Description
MAC Address MAC address of the current port
Mode Port mode is set either manually or via the autonegotiation process.
Note: When autonegotiation protocols do not support each other, this degrades connection to a
half-duplex mode.
In order to avoid this, autonegotiation should be disabled and the ports should be
configured/forced manually. Half-duplex degradation will occur also when autonegotiation is
enabled at one port and disabled at the opposite port.
Rate (Mbps) Port rate is set either manually or via the autonegotiation mode
Status Link status: Connected – Normal operation.
Not connected – Ethernet link loss
Active LAN Displays a currently active LAN port, if Ethernet redundancy is enabled
Frames received from the user
Total Frames The number of frames successfully received. When a valid connection is established the number
should increase steadily.
Total Octets The number of octets successfully received. When a valid connection is established the number
should increase steadily.
Oversize Frames Number of received frames which meet the following conditions:
• Frame data length equals or is greater than 1518/1536 bytes
• Frame has valid CRC
Fragments
Number of received frames which meet the following conditions:
• Frame data length is less than 64 bytes
• Frame has invalid CRC
• Collision event has not been detected
• Late collision event has not been detected
Frames transmitted to the user
Jabber Number of received frames which meet the following conditions:
• Frame data length is greater than 1518/1536 bytes
• Frame has invalid CRC
Dropped Number of received dropped packets
CRC Errors Number of received frames which meet the following conditions:
• Frame data length is between 64 and 1518/1536 bytes
• Frame has invalid CRC
• Collision event has not been detected
• Late collision event has not been detected
Correct Frames The number of frames successfully transmitted. When a valid connection is established the
number should increase steadily.
Correct Octets The number of octets successfully transmitted. When a valid connection is established the
number should increase steadily.
Collision Number of received frames with collision event detected
