Guys, I have to ASA 5510 with a base licence. I have 8.4 on both of the firewalls, and would like to configure active/passive. Do I need only one security plus lience or two, This text has been copied from cisco.com: http://www.cisco.com/en/US/prod/collateral/vpndevc/ps6032/ps6094/ps6120/prod_brochure0900aecd80402e36.html Failover Licenses (8.3(1) and Later) Failover units do not require the same license on each unit. For earlier versions, see the licensing document for your version. This section includes the following topics: • Failover License Requirements • How Failover Licenses Combine • Loss of Communication Between Failover Units • Upgrading Failover Pairs Failover License Requirements • Failover units do not require the same license on each unit. Older versions of ASA software required that the licenses match on each unit. Starting with Version 8.3(1), you no longer need to install identical licenses. Typically, you buy a license only for the primary unit; for Active/Standby failover, the secondary unit inherits the primary license when it becomes active. If you have licenses on both units, they combine into a single running failover cluster license. • For the ASA 5505 and 5510 ASAs, both units require the Security Plus license; the Base license does not support failover, so you cannot enable failover on a standby unit that only has the Base license.
