Fortinet NSE7_SSE_AR-26 Online Access

The SD-WAN rule (config service edit 1) is configured with set mode priority. This means the rule selects the best interface based on a defined performance metric, as opposed to a simple static priority or SLA. The event log (image_41cfb5.png) shows Metric latency and Message Service prioritized by performance metric will be redirected in sequence order. This indicates that the rule is using latency to determine the preferred member. Given that the log message is about a change, and the most logical reason for a change in a priority mode is that a different member is now the best performer, it implies that the latency on port2 has become lower than that on port1. The log message Service prioritized by performance metric will be redirected in sequence order confirms that FortiGate is changing the member being used for this service. Because the mode is priority, FortiGate dynamically selects the member that currently meets the best performance criteria, which in this case is latency. The log implies a new member has been selected as the most optimal, and with the default configuration, the members are sorted based on their performance, so the outgoing interface list is effectively updated to prefer the new best-performing member (port2).

The FortiManager installation error is associated with the gateway value produced by metadata substitution, not with a general failure of FortiManager-to-FortiGate connectivity. A template uses a variable such as ' $(sdwan_port1_gw) ' to provide the interface gateway at installation time. If the current device has no valid value in its per-device metadata mapping, the generated FortiOS configuration contains an invalid IPv4 gateway and the copy or validation operation fails. Therefore the remediation is to inspect the variable definition and its per-device mapping, which is option C in the normalized question. The administrator can verify the mapping for the affected FortiGate, supply a valid address, regenerate the installation preview and reinstall. It is unnecessary to remove all template installation targets: FortiManager supports them alongside metadata variables. Nor must the members of a zone all use identical gateway configuration methods. This conclusion is specifically tied to the error shown in the original exhibit. The uploaded FortiSASE guides describe centralized management generally, but detailed per-device template substitution belongs to the FortiManager 7.6 Administration Guide.

The application-aware SD-WAN rule can initially route a connection through the implicit SD-WAN rule if its three-tuple (destination IP, port, protocol) has not yet been learned in the application cache. Once the application-control engine identifies GoToMeeting as a Collaboration application, session reevaluation can allow matching of the intended application rule. Depending on state, NAT and route changes, an existing session might not migrate successfully. This mechanism is not universally dependent on deep SSL inspection, and the configured Collaboration category is a legitimate match for GoToMeeting. The first cause is established; the second is a plausible interpretation not proven by the visible log alone. Reference: FortiOS 7.6 — Application Detection Steering; Fortinet Technical Tip — Application Learning Phases. An operational review should distinguish the rule that matches the traffic from the interface that is ultimately selected. Valid forwarding also depends on destination route eligibility, current member state and the applicable SLA or quality-selection algorithm. A diagnostic showing configured members alone is not conclusive evidence that all those members will carry a particular flow.

Verification qualification: The exhibit establishes initial application classification behavior, but not that session route refresh definitely failed.

From the SD-WAN monitor in FortiManager: " The SD-WAN monitor provides a summary view of the branch devices and their members. In the scenario shown, it is clear that branch2_fgt is missing SLA configuration for one member, as evidenced by the lack of performance metrics. The monitor also shows only two branches in the current topology, allowing quick assessment of branch health and configuration completeness. " This kind of visibility is vital for proactive monitoring and rapid troubleshooting in SD-WAN environments.References: FortiManager templates reduce repetitive work but must resolve to valid, device-specific configurations at installation time. Device assignments, metadata mappings, ADOM scope, policy-package interfaces and provisioning order should be inspected together rather than troubleshooting any one object in isolation. A successful management connection does not guarantee a successful configuration installation. Review the installation preview and task log, then validate the resulting device configuration and operational diagnostics. This separates a deployment-time validation failure from a live tunnel, routing or SLA fault.
