Tx KB/s

This field shows the number kilobytes per second transmitted on this port.

Rx KB/s

This field shows the number of kilobytes per second received on this port.

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

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

error.

RX CRC

This field shows the number of packets received with CRC (Cyclic Redundant Check)

error(s).

Length

65-127

This field shows the number of packets (including bad packets) received that were

between 65 and 127 octets in length.
