High Availability
ASAc on Cat9k supports stateless HA and leverages the IOX HA infra of the Catalyst series switches.
ASAc will be running only on the active switch. ASAc on the standby is in a ready to run state.
Configurations are synced between the active & standby every 15mins.
ASAc configurations are persistent across switchover.
ASAc license is shared between active & standby.
On initiating a switchover, downtime of around 90sec is expected for the ASAc on the standby to start processing the traffic.
