Improper Network Topologies
It is important to make sure that you have a valid network topology. Common topology
faults include excessive cable length and too many repeaters (hubs) between end nodes.
In addition, you should make sure that your network topology contains no data path loops.
Between any two ends nodes, there should be only one active cabling path at any time.
Data path loops will cause broadcast storms that will severely impact your network
performance.
10.1 Cabling
RJ-45 ports: use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for
RJ-
45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps connections or 100Ω
Category 5 cable for 100Mbps connections. Also be sure that the length of any twisted-pair
connection does not exceed 100 meters (328 feet). Gigabit port should use Cat-5 or cat-5e
cable for 1000Mbps connections. The length does not exceed 100 meters.
