Explanation

Pre-requisites for HA Both the primary and the secondary server should be of the same size and the same type (VM or physical appliance). Both the primary and the secondary server should have the same Cisco CMX version. Both the primary and the secondary server should be connected on the same subnet. Both the primary and the secondary server should be connected on the same subnet if Layer 2 Both the primary and the secondary server should be IP connected with delay of less then 250ms if Layer 3 HA is used. From Cisco CMX release 10.6.2, NTP server settings must be configured on both Primary and Secondary server instance before HA pairing starts. We recommend that you use the same NTP server on both Primary and Secondary. As a Cisco CMX admin you can also use a dedicated NTP for Primary and Secondary. 6/cmx_config/b_cg_cmx106/managing_cisco_cmx_system_settings.html
