DES-3010F/DES-3010FL/DES-3010G/DES-3018/DES-3026 Fast Ethernet Switch Manual 
The following fields may be set or viewed: 
Parameter                        Description 
Time Interval [1s ] 
Select the desired setting between 1s and 60s, where "s" stands for seconds. The 
default value is one second. 
Record Number [200] 
Select number of times the Switch will be polled between 20 and 200. The default 
value is 200. 
ExDefer 
Counts the number of packets for which the first transmission attempt on a particular 
interface was delayed because the medium was busy. 
CRC Error 
Counts otherwise valid packets that did not end on a byte (octet) boundary. 
LateColl 
Counts the number of times that a collision is detected later than 512 bit-times into the 
transmission of a packet. 
ExColl 
Excessive Collisions. The number of packets for which transmission failed due to 
excessive collisions. 
SingColl 
Single Collision Frames. The number of successfully transmitted packets for which 
transmission is inhibited by more than one collision. 
Coll 
An estimate of the total number of collisions on this network segment. 
Show/Hide 
Check whether or not to display ExDefer, LateColl, ExColl, SingColl, and Coll errors.
