Setting the Hop Count

The hop count specifies the number of  times a CDP request can be forwarded from the command switch to other CDP devices in the network. Consequently, the hop count controls the size of the network map in the Topology view. If, for example, the hop count is 3 (the default), the command switch sends a CDP request to its immediate CDP neighbors, which forward the request to their immediate CDP neighbors, which forward the request for the final time. The outer boundary of the network map is defined by edge devices that receive the CDP request in the final forwarding.

To set the hop count, choose Cluster > Hop Count and use the Hop Count window.

Note: CDP requests are not forwarded by devices that do not support clustering; therefore the cluster cannot be extended beyond these devices.
