How to Plan for Switch Clustering
Figure 7 Discovery Through CDP Hops
Discovery Through Non-CDP-Capable and Noncluster-Capable Devices
If a cluster command switch is connected to a non-CDP-capable third-party hub (such as a non-Cisco hub), it can
discover cluster-enabled devices connected to that third-party hub. However, if the cluster command switch is
connected to a noncluster-capable Cisco device, it cannot discover a cluster-enabled device connected beyond the
noncluster-capable Cisco device.
Figure 8 on page 96 shows that the cluster command switch discovers the switch that is connected to a third-party hub.
However, the cluster command switch does not discover the switch that is connected to a Catalyst 5000 switch.
