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 a cluster-enabled device connected
beyond the noncluster-capable Cisco device.

to a third-party hub. However, the command switch does not discover the Catalyst 2950 switch that is
connected to a Catalyst 5000 switch.
Refer to the release notes for the Catalyst switches that can be part of a switch cluster.
