I am configuring Failover on two ASA5510,but some Failover commands take no effect when I entered them into ASA.
I entered the following commands in the mode of ASA5510A(config)#:
failover lan unit primary
failover link FailOver Ethernet2
ip address 172.16.1.1 255.255.0.0 standby 172.16.1.2
failover interface ip FailOver 10.1.1.1 255.255.255.0 standby 10.1.1.2
Then,two-three commands above did not appear whem I used show run,why?
