DESCRIPTION

 

 

 

and 1518 octets in length.

 

 

>1518

This field shows the number of frames (including bad frames) transmitted that were greater than

 

1518 octets in length.

 

 

Multicast

This field shows the number of good multicast frames received.

 

 

Broadcast

This field shows the number of good broadcast frames received.

 

 

Pause

This field shows the number of 802.3x Pause frames received.

 

 

Tagged

This field shows the number of frames with VLAN tags received.

 

 

Control

This field shows the number of control received (including those with CRC error) but it does not

 

include the 802.3x Pause frames.

 

 

TX Collision

The following fields display information on collisions while transmitting.

 

 

Single

This is a count of successfully transmitted frames for which transmission is inhibited by exactly

 

one collision.

 

 

Multiple

This is a count of successfully transmitted frames for which transmission was inhibited by more

 

than one collision.

 

 

Excessive

This is a count of frames 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 frame have

 

already been transmitted.

 

 

Error Packet

The following fields display detailed information about frames received that were in error.

 

 

RX CRC

This field shows the number of frames received with CRC (Cyclic Redundant Check) error(s).

 

 

Length

This field shows the number of frames received with a length that was out of range.

 

 

Alignment

This field shows the number of frames received of proper size but with CRC error(s) and a non-

 

integral number of octets.

 

 

Runt

This field shows the number of frames received that were too short (shorter than 64 octets),

 

including the ones with CRC errors.

 

 

Dropped Packet

The following filed indicates why frames were dropped.

 

 

Giant

This field shows the number of frames dropped because they were bigger than the maximum

 

frame size.

 

 

Poll Interval(s)

The text box displays how often (in seconds) this screen refreshes. You may change the refresh

 

interval by typing a new number in the text box and then clicking Set Interval.

 

 

Stop

Click Stop to stop port statistic polling.

 

 

Clear Counter

Click this button to erase the recorded statistical information for this port.
