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 application.
Recommendations:
Many collisions indicate that the traffic is too heavy for a half-duplex media. Set to a Full-
Duplex environment if possible.
