Short Events
This counter is incremented by one for each carrier event
whose duration is less than the short event maximum time. Short
events are error frames smaller than the minimum size defined for
802.3 frames. They may indicate externally generated noise causing
problems on the network. Check the cabling routing and re-route any
cabling which may be affected by external noise sources.
Late Events
This counter is incremented by one each time a collision
occurs after the valid packet minimum time. A late event is an
out-of-window collision that may occur if your 802.3 LAN exceeds the
maximum size as defined in the IEEE standard. A late event is also
counted as a collision.
Long Frames
This counter is incremented by one each time a frame is
received whose octet count is greater than the maximum frame size
but less than Jabber frame size. Long Frames are frames that exceed
the maximum size defined for 802.3 frames (1518 octets). If you see a
high number of long frames on your network, you should isolate the
source of these frames and examine the transceiver or adapter card at
the device. Some protocols may generate these frames.
Jabbers
The total number of packets received that were longer than 8K
octets (excluding framing bits, but including FCS octets).
CLEAR SCREEN COUNTERS
Select this button to set all counters
shown on the screen to zero. It is useful for trend analysis if you wish to
see changes in counters over a short period of time. This button does
not clear the counters on the device or affect counters at the network
management station.
