Figure 1-1 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 1-2 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.
