Configuring a Redundant Link
BNC:
An Example Configuration
According to the priority scheme described above, BNC will not be the active uplink if either an AUI or 10T connection exists. Due to this ordering, if BNC is selected, it is assumed that this medium is the only type available.
There are different redundant link cabling schemes which can be used to provide increased network reliability.This example illus- trates one possible scenario. The concepts here can be applied to other possible redundant cabling schemes.
