E-FL-HB-0x00 in Half-Duplex Network
The 5-4-3 Rule applies separately to each collision domain. NOTE: A
collision domain is any Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) network in which a collision will occur if two attached stations
transmit at the same time. A segment is the cable connection between two
network interfaces.
USING THE 5-4-3 RULE:
The 5-4-3 Rule allows no more than five segments in any 10-Mb/sec
Ethernet collision domain, no more than four repeaters (hubs) and no
more than three populated segments (10Base-2 or 10BASE-5 coaxial-
cable installations).
To determine the size of the collision domain by assigning segment
numbers to cable connections, determine the two network devices in a
transmission path that are separated by the greatest number of segments.
Define a segment path between the network devices by labeling the
cable connection to the first device “segment 1”and numbering each
segment in the path to the last network device, up to “segment n”(n =
total number of segments ≤5). Verify that no segment path in the entire
collision domain contains more than n ≤5 segments.
