LABEL DESCRIPTION
Multicast This field shows the number of good multicast frames received.
Broadcast This field shows the number of good broadcast frames received.
Pause This field shows the number of 802.3x Pause frames received.
Control This field shows the number of control received (including those with CRC error) but it does not
include the 802.3x Pause frames.
TX Collision
The following fields display information on collisions while transmitting.
Single This is a count of successfully transmitted frames for which transmission is inhibited by exactly
one collision.
Multiple This is a count of successfully transmitted frames for which transmission was inhibited by more
than one collision.
Excessive This is a count of frames 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 frame have
already been transmitted.
Error Packet The following fields display detailed information about frames received that were in error.
RX CRC This field shows the number of frames received with CRC (Cyclic Redundant Check) error(s).
Length This field shows the number of frames received with a length that was out of range.
Runt This field shows the number of frames received that were too short (shorter than 64 octets),
including the ones with CRC errors.
Distribution
The following fields display the number of frames received.
64 This field shows the number of frames (including bad frames) received that were 64 octets in
length.
65 to 127 This field shows the number of frames (including bad frames) received that were between 65
and 127 octets in length.
128 to 255 This field shows the number of frames (including bad frames) received that were between 128
and 255 octets in length.
256 to 511 This field shows the number of frames (including bad frames) received that were between 256
and 511 octets in length.
512 to 1023 This field shows the number of frames (including bad frames) received that were between 512
and 1023 octets in length.
