and integral lengths.

 

 

 

 

EtherStatsJabbers

than 1518 octets (non VLAN) or 1522 octets (VLAN) and contained an

 

 

invalid FCS, including alignment errors.

 

 

 

 

EtherStatsCollisions

maximum collisions before the retransmission count is reset.

 

 

 

 

EtherStats64Octets

This is the number of frames received/transmitted (including bad

but excludes framing bits).

 

 

 

 

EtherStats65to127Octets

This is the number of frames received/transmitted (including bad

 

 

frames) that were 65 to 127 octets in length (this includes FCS octets

 

 

but excludes framing bits).

 

 

 

 

EtherStats128to255Octets

This is the number of frames received and transmitted (including bad

 

 

frames) that were 128 to 255 octets in length (this includes FCS octets

 

 

but excludes framing bits).

 

 

 

 

EtherStats256to511Octets

This is the number of frames received/transmitted (including bad

 

 

frames) that were 256 to 511 octets in length (this includes FCS octets

 

 

but excludes framing bits).

 

 

 

 

EtherStats512to1023Octets

This is the number of frames received/transmitted (including bad

 

 

frames) that were 512 to 1023 octets in length (this includes FCS

 

 

octets but excludes framing bits).

 

 

 

 

EtherStats1024to1518Octets

This is the number of frames received/transmitted (including bad

 

 

frames) that were 1024 to 1518 octets in length (this includes FCS

 

 

octets but excludes framing bits).

 

 

 

 

Poll Interval(s)

The text box displays how often (in seconds) this screen refreshes.

 

Set Interval

You may change the refresh interval by typing a new number in the text
