ASA(config)# failover link failover Management0/0 If you do show running-config you will see that the description of interface Management 0/0 has changed to "description LAN/STATE Failover Interface". Type the following commands ASA(config)# failover lan unit primary ASA(config)# failover lan interface failover Management0/0 When you type this command the ASA will say "INFO: Non-failover interface config is cleared on Management0/0 and its sub-interfaces" and it will give a description to that interface as "description LAN Failover Interface" ASA(config)# failover interface ip failover 192.168.150.1 255.255.255.0 standby 192.168.150.2Ģ. Make sure interface has no interface name "no nameif". For management interface, do a no shutdown. Interfaces need to be on different networks. For instance for inside network with IP address 192.168.99.1 255.255.255.0, pick an ip address for the standby like 192.168.99.2 (no mask needed) and configure that interface: ip address 192.168.99.1 255.255.255.0 standby 192.168.99.2 Do the same thing for all other interfaces that you are going to use like the Outside and DMZ.
The standby will have 192.168.150.2 Primary ASA: For each interface with IP address and mask pick an ip address for the standby from the same network. Pick a network and IP address for that interface like 192.168.150.1. You could use the Management interface management0/0 for that. Connect the two ASAs through a cat5 cable for fail-over link (Heartbeat). Note that Important: If you have An圜onnect or VPN images loaded on the primary, you need to copy them into the secondary because again that will not replicate - only configuration will replicate. After failover is configured, configuration from primary will replicate to standby.
#Failover configuration asa asdm manual
Before upgrading to 8.3 (in case you want to but you don't have to), study well! Access Lists and NAT are different so you need to do manual clean up and re-configuration. If you are running ASA IOS 8.3 and above, licenses don't need to match. From "Show version" compare the licenses installed. Two Cisco ASAs have identical hardware specs. What we need to pay attention? Lets start. 1.How to Configure Hot Failover-Cisco ASA 5510 and ASA 5500 Series-ActiveStandby? In this article, the author told the detailed info of Cisco asa 5505, 5500 failover configuration from primary to standby.
