Failover and Scan Interfaces

In a failover pair, although the scan interfaces are enabled only on the primary system, the scan interface configurations are replicated on both systems. When the primary fails, the secondary activates its scan interfaces (physical and virtual) using the same IP configurations. Both the primary and the secondary can access the network using the same scan interface configurations. After a failover, the NetMRI appliance continues to interact with the devices using the same scan interfaces.

If no scan interfaces are configured on both failover systems, then the NetMRI appliances interact with network devices using the management port. The physical management port configuration is not replicated between the systems. After a failover, the NetMRI appliance interacts with the devices using the management port of the local system. Therefore, you have to configure the management IPs and infrastructure ACLs on both systems.
