LABEL

DESCRIPTION

 

Single

This is a count of successfully transmitted packets for which transmission is

 

 

inhibited by exactly one collision.

 

 

 

 

Multiple

This is a count of successfully transmitted packets for which transmission

 

 

was inhibited by more than one collision.

 

 

 

 

Excessiv

This is a count of packets for which transmission failed due to excessive

 

e

collisions. Excessive collision is defined as the number of maximum

 

 

collisions before the retransmission count is reset.

 

 

 

 

Late

This is the number of times a late collision is detected, that is, after 512

 

 

bits of the packets have already been transmitted.

 

 

 

 

Error Packet

The following fields display detailed information about packets received

 

 

that were in error.

 

 

 

 

RX CRC

This field shows the number of packets received with CRC (Cyclic

 

 

Redundant Check) error(s).

 

 

 

 

Length

This field shows the number of packets received with a length that was out

 

 

of range.

 

 

 

 

Runt

This field shows the number of packets received that were too short

 

 

(shorter than 64 octets), including the ones with CRC errors.

 

 

 

 

Distribution

 

 

 

 

 

64

This field shows the number of packets (including bad packets) received

 

 

that were 64 octets in length.

 

 

 

 

65 to

This field shows the number of packets (including bad packets) received

 

127

that were between 65 and 127 octets in length.

 

 

 

 

128 to

This field shows the number of packets (including bad packets) received

 

255

that were between 128 and 255 octets in length.

 

 

 

 

256 to

This field shows the number of packets (including bad packets) received

 

511

that were between 256 and 511 octets in length.

 

 

 

 

512 to

This field shows the number of packets (including bad packets) received

 

1023

that were between 512 and 1023 octets in length.

 

 

 

 

1024 to

This field shows the number of packets (including bad packets) received

 

1518

that were between 1024 and 1518 octets in length.

 

 

 

 

Giant

This field shows the number of packets dropped because they were bigger

 

 

than the maximum frame size.
