Note: Intrusion Detection and Prevention (IDP) services do not support failover. For this reason, IDP services will not be applied for sessions that were present prior to the failover. IDP services will be applied for new sessions created on the new primary node. |
The fabric data link is vital to the chassis cluster. If the link is unavailable, traffic forwarding and RTO synchronization are affected, which can result in loss of traffic and unpredictable system behavior.
To eliminate this possibility, JUNOS software detects fabric faults and disables one node of the cluster. It determines that a fabric fault has occurred if a fabric probe is not received but the fabric interface is active.
To recover from this state, you must reboot the disabled node. When you reboot it, the node synchronizes its state and RTOs with the primary node.

Note: If you make any changes to the configuration while the secondary node is disabled, execute the commit command to synchronize the configuration after you reboot the node. If you did not make configuration changes, the configuration file remains synchronized with that of the primary node. |
