LABEL DESCRIPTION
Tx This field shows the percentage of actual transmitted frames on this port as a percentage of the
Utilization%
Link speed.
Rx kB/s This field shows the number of kilobytes per second received on this port.
Rx This field shows the percentage of actual received frames on this port as a percentage of the Link
Utilization%
speed.
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.
Unicast This field shows the number of good unicast packets 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.
Unicast This field shows the number of good unicast packets 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) errors.
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 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.
