Parameter Description
Frames Received
Total Frames The total number of correct frames received. When a valid connection is established the number
should increase steadily.
Total Octets The total number of octets (bytes) received. When a valid connection is established the number should
increase steadily.
Oversize
Frames
Number of frames exceeding the maximum allowed frame size, but are otherwise valid Ethernet frames
(good CRC).
Fragments The number of frames that are shorter than 64 bytes and have an invalid CRC.
Jabber The number of frames that are too long and have an invalid CRC.
A jabber is transmission by a data station beyond the time interval allowed by the protocol, usually
affecting the rest of the network. In an Ethernet network, devices compete for use of the line,
attempting to send a signal and then retrying in the event that someone else tried at the same time. A
jabber can look like a device that is always sending, effectively bringing the network to a halt.
Recommendations
Check network interface card or any other transmitting devices and external electrical interference.
Dropped
Frames
Number of dropped frames due to delivery problems.
Recommendations:
Check the network interface card.
CRC Errors The amount of frames with invalid CRCs.
Frames Transmitted
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.
Collisions The number of successfully transmitted frames which transmission is inhibited by a collision event. A
collision occurs in half-duplex connection when two devices try to transmit at the same time. This
counter tracks the number of times frames have collided. This event exists only in half duplex mode,
which is not recommended in an IPmux-11 application.
Recommendations:
Many collisions indicate that the traffic is too heavy for a half duplex media. Set to a full duplex
environment if possible.
