Error Source
This area of the Repeater Configuration view provides a series of buttons
allowing you to select the types of errors to include in the error sum. The
selectable error types are as follows:
CRC
Describes the number of packets received by the module with bad CRC
(Cyclical Redundancy Checks).
Runts
Describes the number of runt packets received by the module. A runt packet is
one byte less than the standard Ethernet frame of 64 bytes (not including
preamble).
OOW_Colls
Describes the number of collisions out of the standard window (51.2 µs) due to
a network problem.
Alignment
Describes the number of misaligned packets detected by the module.
No_Resource
Describes the number of times the module ran out of resources (i.e., lack of
buffer space) and could not accept packets.
Giants
Describes the number of giant packets received by the module. A giant packet
exceeds 1518 bytes (not including preamble).
