A next-generation firewall does this as well and it also incorporates features such as application awareness and control, integrated intrusion prevention, and cloud-delivered threat intelligence. A traditional firewall normally offers stateful inspection of incoming and outgoing network traffic. The basic failover configuration is presented below :įailover lan interface FAILOVER GigabitEthernet0/6įailover link STATEFULL GigabitEthernet0/7įailover interface ip FAILOVER 192.168.1.1 255.255.255.252 standby 192.168.1.2įailover interface ip STATEFULL 192.168.2.1 255.255.255.252 standby 192.168.2.2įailover lan interface FAILOVER GigabitEthernet0/6įailover interface ip FAILOVER 192.168.1.1 255.255.255.252 standby 192.168.1.2įailover interface ip STATEFULL 192.168.2.1 255.255.255.252 standby 192.168.2.A next-generation firewall (NGFW) is a network security device with capabilities that go beyond those of a traditional, stateful firewall. The standby IP and MAC goes to the standby unit. If the failover condition is me t, the standby unit becomes active and acquires an active IP address an d MAC. Based on the defined time, the failover condition is checked.

Standby has an identical configuration as active and pools an active unit with keepalive packets. Platform: Cisco ASA 5505, 5500, 5525 Description :Īctive-Standby failover means that two units are working in an active-standby configuration where the active state is always present on one of the failover pairs.
