Ensure 'Failover' is enabled

MoyenneNiveau 1Automatiséecisco-asa

Description

Enables failover between the security appliance and another security appliance in order to achieve high availability. Enabling failover helps to meet the availability requirement of the security CIA (Confidentiality - Integrity - Availability) triad, ensuring a physical and logical redundancy of firewalls in order to avoid service disruption should the security appliance or ...

! Follow the steps below to enable active/standby failover. The commands are run in the system execution space - Step 1: For each appliance, identify the failover link physical interface <failover_interface_physical> and assign it a name <failover_interface_name> and IP address <failover_interface_ip> and subnet mask <failover_interface_mask>. Identify the other device IP address for each appliance as <peer_failover_ip> - Step 2: For each appliance, identify the state link physical interface <state_interface_physical> and assign it a name <state_interface_name> and IP address <state_interface_ip> and subnet mask <state_interface_mask>. Identify the other device IP address for each appliance as <peer_state_ip> - Step 3: Run the following on the Active device to set it as primary node failover lan unit primary - Step 4: Run the following on the Standby device to set it as secondary node failover lan unit secondary - Step 5: Run the following on both security appliances failover lan interface <failover_interface_name> <failover_interface_physical> failover interface ip <failover_interface_name> <failover_interface_ip> <failover_interface_mask> standby <peer_failover_ip> interface <failover_interface_physical> no shutdown failover link <state_interface_name> <state_interface_physical> failover interface ip <state_interface_name> <state_interface_ip> <state_interface_mask> standby <peer_state_ip> interface <state_interface_physical> no shutdown failover write memory - Step 6: Set up IPSEC preshared key failover ipsec pre-shared-key *
