Ensures service continuity for bridged and routed traffic by synchronizing firewall states between two identical, redundantly connected Smart Switches. If a failure or service outage occurs, the system automatically deflects traffic to the healthy peer to maintain stateful inspection and network operation.
High Availability and Redundancy
Describes Hypershield HA requirements, connectivity, synchronization, supported peer configurations, and limitations for maintaining stateful traffic inspection during switch or DPU failures.
Service Traffic Deflection
Describes that when high availability is configured, if the firewall service subsystem is not ready to process traffic despite the networking infrastructure being fully operational, traffic is deflected to the HA peer that is ready, to minimize traffic loss.
Configure connectivity for High Availability
Configure the High Availability (HA) connectivity, establish the loopback IP reachability through static routes or routing protocols over this HA connection.
Configure High Availability
Configure Hypershield high availability by setting a loopback source interface, specifying the peer IP address, and activating HA.
Verify High Availability
View the command outputs of the show running-config service-acceleration and show service-acceleration high-availability status to understand the configuration of the service acceleration feature on the switch.
