When modeling Cisco ASA firewalls, Spectrum appends _primary or _secondary to the model name to represent when the model is in a primary or secondary state. This is described in CA documentation:

Cisco Adaptive Security Appliance (ASA) device family delivers enterprise-class firewall capabilities for ASA devices in an array of form factors - standalone appliances, blades, and virtual appliances - for any distributed network environment. ASA software also integrates with other critical security technologies to deliver comprehensive solutions that meet continuously evolving security needs. Cisco ASA devices offers a combination of enterprise-class stateful firewalls with a comprehensive range of next-generation network security services.
With respect to Cisco ASA (Adaptive Security Appliance) devices failover, Spectrum now has the following capabilities:
1. Identifies Primary and Secondary device and appends the text to model name.
2. Generates alarm if the Primary device goes to standby.
3. Changes the ASA device status to Active/Standby or Active/Active.
4. Polls and discovers changes of Failover States of Cisco ASA Firewalls
5. Discover Connections and update the topology, when the failover occurs
The two Cisco ASA Firewalls are in a Primary and Secondary Mode, which ideally means that Primary Firewall is Active, whereas the Firewall in secondary mode is in Standby.
When a failover happens, the two Firewall devices switch their configuration.
This means that they switch their Management IP Address as well. This Management IP Address is used to model both devices in Spectrum.
The MAC Addresses for active interfaces are also switched.
When failover occurs on the primary device, secondary firewall device should become Active and primary firewall device becomes Standby.
The following text: “_Primary” & “_Secondary” is appended to the model name automatically in the topology view.
