Table3-2. Network Statistics (continued)
Statistic Description
BusWait Drops Thenumber of packets dropped due to waiting too
longfor a bus to become available.
BadTypes/Lengths Thenumber of unknown packet types if Ethernet
DIXencapsulation is being used. The number of
packetswith illegal lengths if IEEE 802.2/802.3
encapsulationis being used.
Frames Sent Thenumber of framessent.
Carrier Sense
Losses The number of times packets could not be
transmittedbecause the Remote Access
Concentratorlost the Carrier Sense signal – usually
theresult of excessive traffic on the Ethernet.
Clearto Send
Losses The number of times packets could not be
transmittedbecause the Remote Access
Concentratorlost the Clear to Send signal – usually
theresult of a serious hardware failure or
incompatibility.
CollisionsDetected Thenumber of times theRemote Access
Concentratorhad to retry transmissions
automatically– usually the resultof normal Ethernet
traffic.These retriesdo not cause the boot command
todisplay ‘‘*.”
ExcessiveCollision
Losses The numberof times the Remote Access
Concentratorcould not transmit packets because
therewere too many collisions – usually the result
ofexcessive traffic on the Ethernet (but can be due
towiring e rrors or hardware failure). The boot
commanddisplaystheseretriesas“*.”
