Losses

Collisions Detected

The number of unknown packet types if Ethernet IP encapsulation is being used. The number of packets with illegal lengths if IEEE 802.2/802.3 IP encapsulation is being used.

The number of frames sent.

The number of times packets could not be transmitted because the CSMIM-T1 lost the Carrier Sense signal – usually the result of excessive traffic on the Ethernet.

The number of times packets could not be transmitted because the CSMIM-T1 lost the Clear to Send signal – usually the result of excessive traffic.

The number of times the CSMIM-T1 had to retry transmissions automatically – usually the result of normal Ethernet traffic. These retries do not cause the boot command to display ‘‘*.”

 

The number of times the CSMIM-T1 could not transmit

Excessive Collision

packets because there were too many collisions –

Losses

usually the result of excessive traffic on the Ethernet.

 

The boot command displays these retries as “*.”
