Management Center for Cisco Security Agents High Availability White Paper
Source: Cisco Systems
This whitepaper discusses the Management Center for Cisco Security Agents (CSA MC) High Availability (HA) solution. The CSA MC high availability solution uses a primary and secondary CSA MC to provide agents with maximum access to a Management Center. Generally, Cisco Security Agents (agents) communicate with CSA MC when it is in the "reachable" system state. When the CSA MC is not reachable, the agents will not send events, receive software upgrades, or receive policy updates. The CSA MC may not be reachable for many reasons including scheduled upgrades, network connectivity issues, the CSA MC service has been stopped, or there has been a server outage.
