LABEL | DESCRIPTION |
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 Packet | 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. |
|
|
Tagged | This field shows the number of packets with VLAN tags transmitted. |
|
|
Rx Packet
The following fields display detailed information about packets received.
RX Packet | 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. |
|
|
Control | This field shows the number of control packets received (including those with CRC |
| error) but it does not include the 802.3x Pause packets. |
|
|
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 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. |
|
|
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. |
