Chapter 7 System Status and Port Statistics Table 9 Port Details (continued) LABEL DESCRIPTION TX Collision The following fields display information on collisions while transmitting. 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. 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 to 127 This field shows the number of packets (including bad packets) received that were between 65 and 127 octets in length. 128 to 255 This field shows the number of packets (including bad packets) received that were between 128 and 255 octets in length. 256 to 511 This field shows the number of packets (including bad packets) received that were between 256 and 511 octets in length. 512 to 1023 This field shows the number of packets (including bad packets) received that were between 512 and 1023 octets in length. 1024 to 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.

TX Collision
The following fields display information on collisions while transmitting.
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.
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 to 127
This field shows the number of packets (including bad packets) received that were between
65 and 127 octets in length.
128 to 255
This field shows the number of packets (including bad packets) received that were between
128 and 255 octets in length.
256 to 511
This field shows the number of packets (including bad packets) received that were between
256 and 511 octets in length.
512 to 1023
This field shows the number of packets (including bad packets) received that were between
512 and 1023 octets in length.
1024 to 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 47 on page
381
