Configuring CDP for Extended Discovery
You can change the default configuration of CDP on the command switch to continue discovering
devices up to seven hops away. Figure 6-4 shows a command switch that can discover candidates and
cluster members up to seven devices away from it. Figure 6-4 also shows the command switch connected
to a Catalyst 5000 series switch. Although the Catalyst 5000 supports CDP, it does not support
clustering, and the command switch cannot learn about connected candidate switches connected to it,
even if they are running CMS.
