How to tell if Active/active or Active/Standby mode is configure
If you don't have multiple context configured, it is definitely just Active/Standby failover. Active/Active failover basically means that if you have multiple context configured, you can have some context active on 1 unit, and some other context active on another unit.
If under the output of "show failover" on the "Stateful Failover Logical Update Statistics" section, you have an interface configured and it's UP, and the stats are showing some numbers, that means stateful failover is configured.
OR, you can also check the configuration, and if you have "failover link" command configured, that means stateful failover is configured.
In your configuration it will be configured like this.... this configuration shows that the unit is primary.... so this one is active and the other unit is standby...also it has two different failover configured.... lan and state which describes the LAN failover and stateful failover...
