I have two ASA 5510 with 7.06 sowftware (Security Plus licence), this is the original image the device came with it. When I upgrade to 7.22 the sh ver output says Failover suppport Acitve/Active,while the original image supports Active/Standby and I need Standby option. How can activate Standby option?
You dont need to worry about failover support showing "Active/Active", this will still support "Active/Stnadby". Now you just need to make sure that the supposed to be secondary ASA atleast has failover support of "Active/Standby", to configure these ASA's in Active/Standby failover scenario.
