To accept a management request and successfully establish and maintain the connection, the following must be in place on the Central Management System appliance:
The Central Management System appliance has the rendezvous process enabled
The rendezvous process is enabled by default.
The Central Management System appliance has a permanent hostname
If the hostname is changed, the connection will be broken and cannot be reset. If this happens, the appliance must be removed from the Central Management System appliance and then added again using the new hostname.
The Central Management System and requesting appliances have the same service name
The rendezvous process has an identifier (known as service name) that is set to "cmc" by default. The Central Management System appliance and the requesting appliance must have the same service name; if you change the service name on one, you must change it on the other as well.
Use the cmc rendezvous service-name <hostname> command to change the service name. Use the no cmc rendezvous service-name command to restore the default value. For details, see the CLI Command Reference.
