Task 1: Identify the Current Topology
5. In the Attributes pane, check the Configuration Tag attribute.
6. To identify the topology, compare the attribute value with the supported
configuration tags shown in Table 4-3.

*A cluster using the split-star topology with only one cluster switch per fabric uses the same configuration tag as
a cluster using the star topology if the cluster switch occupies position 1. You can identify the topology by
checking the configuration revision. A star topology cluster switch has a configuration revision of 0_0. A split-star
topology cluster switch has a configuration revision of 1_7 or higher. See Table 4-9
on page 4-12.
