Failover asa 9 - missing something

manuscript1
Level 1
Level 1

Hi

I am having problem getting a failover working between two asas. They are both routed and single context and same licence. . I have a crossover in the eth0/2 interface . ( ive changed Ip addresses to protect the innocent ).

I have tried reloading the backup firewall with no luck .....

Any ideas ?

secondary unit shows:

I have fixed this . I had done some manual config on the standby  on the backup . I cleared the config on the standby and added the failover commands and it all came to life

Hi,

From the snippet i can see that the failover configuration on the two units are different

failover
failover lan unit primary
failover lan interface failover Ethernet0/2
failover key *****
failover link statelink Ethernet0/3
failover interface ip failover 10.129.192.161 255.255.255.252 standby 10.129.192.162
failover interface ip statelink 10.129.192.166 255.255.255.252 standby 10.129.192.165

**

failover

failover lan unit secondary
failover lan interface failover Ethernet0/2
failover key *****
failover interface ip failover 10.129.192.162 255.255.255.252 standby 10.129.192.161

The failover interface IP address assignment has to be same on both the units. Also you have configured state link on the primary unit and not on the secondary unit. Please configure state link on both the units and correct the failover interface ip addresses on the secondary unit. Following should be the configuration on the secondary unit

failover
failover lan unit seconadary
failover lan interface failover Ethernet0/2
failover key *****
failover link statelink Ethernet0/3
failover interface ip failover 10.129.192.161 255.255.255.252 standby 10.129.192.162 -->these IP addresses are incorrectly assigned
failover interface ip statelink 10.129.192.166 255.255.255.252 standby 10.129.192.165
