Chapter 5 Clustering Switches
Planning a Switch Cluster
Discovery through Non-CDP-Capable and Noncluster-Capable Devices
If a 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 command switch
is connected to a noncluster-capable Cisco device, it cannot discover cluster-enabled device connected
to that noncluster-capable Cisco device.
Figure 5-2 shows that the command switch discovers the Catalyst 3500 XL switch, which is connected
to a third-party hub. However, the command switch does not discover the Catalyst 2950 switch that is
connected to a Catalyst 5000 switch.
