Chapter 7 System Status and Port Statistics Table 7 Status: Port Details (continued) LABEL Excessive Late Error Packet RX CRC Runt Distribution 64 65-127 128-255 256-511 512-1023 1024-1518 Giant DESCRIPTION This is a count of packets for which transmission failed due to excessive collisions. Excessive collision is defined as the number of maximum collisions before the retransmission count is reset. This is the number of times a late collision is detected, that is, after 512 bits of the packets have already been transmitted. The following fields display detailed information about packets received that were in error. This field shows the number of packets received with CRC (Cyclic Redundant Check) error(s). This field shows the number of packets received that were too short (shorter than 64 octets), including the ones with CRC errors. This field shows the number of packets (including bad packets) received that were 64 octets in length. This field shows the number of packets (including bad packets) received that were between 65 and 127 octets in length. This field shows the number of packets (including bad packets) received that were between 128 and 255 octets in length. This field shows the number of packets (including bad packets) received that were between 256 and 511 octets in length. This field shows the number of packets (including bad packets) received that were between 512 and 1023 octets in length. This field shows the number of packets (including bad packets) received that were between 1024 and 1518 octets in length. This field shows the number of packets (including bad packets) received that were between 1519 octets and the maximum frame size. The maximum frame size varies depending on your switch model.

Excessive
This is a count of packets for which transmission failed due to excessive
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).
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.
65-127
This field shows the number of packets (including bad packets)
received that were between 65 and 127 octets in length.
128-255
This field shows the number of packets (including bad packets)
received that were between 128 and 255 octets in length.
256-511
This field shows the number of packets (including bad packets)
received that were between 256 and 511 octets in length.
512-1023
This field shows the number of packets (including bad packets)
received that were between 512 and 1023 octets in length.
1024-1518
This field shows the number of packets (including bad packets)
received that were between 1024 and 1518 octets in length.
Giant
This field shows the number of packets (including bad packets)
received that were between 1519 octets and the maximum frame size.
The maximum frame size varies depending on your switch model. See
Chapter 41 on page 327
