Up Time This field shows the total amount of time the connection has been up.
Tx Packet
The following fields display detailed information about packets transmitted.
TX
Packets
This field shows the number of good packets (unicast, multicast and broadcast) transmitted.
Multicast This field shows the number of good multicast packets transmitted.
Broadcast This field shows the number of good broadcast packets transmitted.
Pause This field shows the number of 802.3x Pause packets transmitted.
Rx Packet
The following fields display detailed information about packets received.
RX
Packets
This field shows the number of good packets (unicast, multicast and broadcast) received.
Multicast This field shows the number of good multicast packets received.
Broadcast This field shows the number of good broadcast packets received.
Pause This field shows the number of 802.3x Pause packets received.
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).
Length This field shows the length of the packet received that were in error.
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.
