Question

A network engineer is deploying multiple Policy Service Nodes (PSNs) behind a load balancer at a data center. Management wants the PSNs to detect a peer failure quickly and reset any orphaned RADIUS/TACACS+ sessions so endpoints can re-authenticate against a surviving node. Which PSN configuration should the engineer implement to meet this requirement?

Accepted Answer

Assign the PSNs to the same Node Group so they share session information via multicast/heartbeat and handle failover of orphaned sessions

Answer

Enable the Monitoring persona on each PSN so they can track and clear peer sessions

Answer

Promote one PSN to a secondary PAN so it can synchronize session state across the group

Answer

Configure the pxGrid persona on the PSNs to publish session context to peers for failover
