Local Management C H A P T E R 5 Using Local Management Late Collision: The number of collisions detected after the allowable detection period. This usually occurs in networks where cables are longer than the IEEE specification. MAC Rx Error: The number of received packets containing Rx Error events. Dropped Frames: The number of frames dropped by this port since the last switch reboot. Undersize Frames: The number of frames detected that are less than the minimum permitted frame size of 64 bytes and have a good CRC. Undersize frames usually indicate collision fragments, a normal network event. Total errors: The total number of errors detected since the last switch reboot. Total errors include everything listed in this error table. Collisions: A collision occurs when two devices try to transmit at the same time. This counter tracks the number of times packets have collided on this port. Collisions are normal in an Ethernet network and tend to increase as network utilization rises. Therefore, if the collision rate increases without an increase in network utilization, it might indicate a problem. 460T Ch5 - Sec 2-VLANs-Monitoring-Tools.p65109 4/19/00, 1:55 PM 109

Local Management
Late Collision:
The number of collisions detected after the allowable
detection period. This usually occurs in networks where cables are longer
than the IEEE specification.
MAC Rx Error:
The number of received packets containing Rx Error
events.
Dropped Frames:
The number of frames dropped by this port since the
last switch reboot.
Undersize Frames:
The number of frames detected that are less than the
minimum permitted frame size of 64 bytes and have a good CRC.
Undersize frames usually indicate collision fragments, a normal network
event.
Total errors:
The total number of errors detected since the last switch
reboot. Total errors include everything listed in this error table.
Collisions:
A collision occurs when two devices try to transmit at the same
time. This counter tracks the number of times packets have collided on this
port. Collisions are normal in an Ethernet network and tend to increase as
network utilization rises. Therefore, if the collision rate increases without
an increase in network utilization, it might indicate a problem.
