Use the drop-down menu to choose from the list of available ports. After you highlight a port from the list, you see the configuration and statistics information for that port.

Configuration

Software Status

Indicates whether the interface has been enabled or disabled by the operator.

Hardware Status

Indicates whether the line protocol for the interface is up or down. Normally, if the Software Status is enabled, the Hardware Status is up. An error condition occurs if the Software Status is enabled and the Hardware Status is down.

Maximum Rate

The rate setting for the ethernet interface, either 10 Mbps or 100 Mbps.

Duplex

The duplex setting for the ethernet interface, either half or full.

Receive/Transmit Statistics

Receive

Good Bytes Input

The total number of error-free bytes received by the system.

Total Bytes Input

The total number of bytes, including data and MAC encapsulation, received by the system.

Unicast Packets

The number of packets received in point-to-point communication.

Multicast Packets

The number of packets received that were sent as a transmission to a set of nodes.

Broadcast Packets

The total number of broadcast packets received by the interface.

Source Address Change

The number of times a source MAC address change has been detected on the port.

Undersize Packets

The number of packets received that were less than 64 octets in length (excluding framing bits but including FCS octets).

Oversize Packets

The number of packets received that were longer than 1518 octets (excluding framing bits but including FCS octets).

Excessive Size Packets

The number of packets received that were over the maximum frame size of 1500 + vlan tag.

Pauses (Control Frames)

The number of control frames that were received at the gigabit level. This counter is available only on a Gigabit Ethernet port.

Packets Up To 64 Bytes

The number of received packets (including bad) that were less than 64 bytes in length.

Packets Up To 127 Bytes

The number of received packets (including bad) that were less than 127 bytes in length.

Packets Up To 255 Bytes

The number of received packets (including bad) that were less than 255 bytes in length.

Packets Up To 511 Bytes

The number of received packets (including bad) that were less than 511 bytes in length.

Packets Up To 1023 Bytes

The number of received packets (including bad) that were less than 1023 bytes.

Transmit

Bytes Output

The total number of bytes, including data and MAC encapsulation, transmitted by the system.

Unicast Packets

The number of packets that were requested for transmittal by higher-level protocols but were not addressed to a multicast or broadcast address at this sublayer.

Multicast Packet

The number of packets that were requested for transmittal by higher-level protocols and were addressed to a multicast address at this sublayer.

Broadcast Packets

The number of packets that higher-level protocols requested for transmission.

Frame Deferred

The number of packets that attempted transmission on a particular interface but were delayed because the line was busy. In half duplex mode, a high number of deferrals means that the line is busy with traffic from other stations. In full duplex mode, the link is always available for transmission.

Frame Discards

The number of frames discarded by this port because of excessive transmit delays.

Pauses (Control Frame)

The number of control frames that were transmitted at the gigabit level. This counter is available only on a Gigabit Ethernet port.

Error Statistics

Receive

Drops

The number of events in which packets were dropped by the probe because of a lack of resources.

Jabbers

The number of packets received that were longer than 1518 octets (excluding framing bits but including FCS octets) containing either a bad FCS and integral number of octets or a bad FCS with a non-integral number of octets.

Alignment Errors

The number of packets received that had a length between 64 and 1518 octets (excluding framing bits but including FCS octets) containing a bad FCS and a non-integral number of octets.

FCS Errors

The number of packets received that had a length between 64 and 1518 octets (excluding framing bits but including FCS octets) containing a bad FCS and an integral number of octets.

Fragmentation

The number of packets received that were less than 64 octets in length (excluding framing bits but including FCS octets) with either a bad FCS and an integral number of octets or a bad FCS and a non-integral number of octets.

Symbol Errors

The number of symbols received that the system could not correctly decode. A symbol is a group of bits that are outputted from the encoding of raw data. The number of bits in the symbol depends on the encoding scheme used.

Transmit

Drops

The number of events in which packets were dropped by the probe because of a lack of resources.

Total Collisions

The total number of collisions on this Ethernet segment.

Single Collisions

The total number of single collisions on this Ethernet segment. A station detects a collision in the receive mode when three or more stations are transmitting simultaneously.

Multiple Collisions

The total number of multiple collisions on this Ethernet segment.

Late Collisions

The total number of late collisions on this Ethernet segment.

Excessive Collisions

The total number of excessive collisions on this Ethernet segment.
