* Session Table Overview:
* The session table in FortiOS tracks all active and pending sessions. It includes details like the type of session (TCP, UDP, etc.), status, and statistics.
* Interpreting the Exhibit:
* The exhibit from thediagnose sys session statcommand shows detailed session statistics.
* The specific value indicating "166 TCP sessions waiting to complete the three-way handshake" reflects the number of sessions that have initiatedbut not yet completed the TCP three-way handshake process (SYN, SYN-ACK, ACK).

The BGP summary output shows the state of the 10.200.3.1 peer as "Connect." This state indicates that the local router has attempted to initiate a BGP session with the peer, but the peer has not yet responded to the initial connection request.
* State Explanation: The "Connect" state in BGP indicates that the TCP connection has been initiated but
* is waiting for a response. If the peer does not respond within the configured timers, the session will transition to the "Active" state and retry the connection.
* Possible Causes: This can occur due to network issues preventing the peer from responding, a misconfiguration on the peer device, or issues like access control lists (ACLs) blocking the BGP traffic.
To troubleshoot, check the connectivity between the routers, ensure that the BGP configurations on both sides match, and verify that there are no firewalls or ACLs blocking the BGP packets.

* Logon Event on Collector Agent:The debug output indicates that the logon event is recorded, showing that the collector agent on Windows is logging user activities and transmitting this data to the FortiGate.
* DC Agent Mode:The presence of detailed logon events and their corresponding metadata, such as the domain and workstation information, suggests that the FortiGate is using DC agent mode. This mode involves an agent installed on the Domain Controller (DC) to capture and forward logon events.

The routing table shown in the exhibit lists all the routes known to the FortiGate device. It includes routes learned through different protocols such as BGP, OSPF, and static routes.
* The entryS * 0.0.0.0/0 [20/0] via 10.200.2.254, port2, [5/0]indicates that there is a static route to the default gateway (0.0.0.0/0) throughport2with a gateway IP of10.200.2.254.
* The asterisk*next to the route signifies that this route is selected and currently active in the forwarding information base (FIB). This means the FortiGate uses this route to forward packets destined for addresses not otherwise specified in the routing table.

The exhibit shows a sniffer capture where TCP port 8013 is being used for communication. The communication appears one-way, indicating potential issues with the upstream FortiGate receiving the necessary packets or being able to respond.
To ensure successful communication in a Security Fabric setup:
* Ensure TCP port 8013 is not blocked along the way: Verify that no firewalls or network devices between the downstream and upstream FortiGates are blocking TCP port 8013. This port is crucial for Security Fabric communication.
* Authorize the downstream FortiGate on the root FortiGate: In the Security Fabric, the root FortiGate must recognize and authorize the downstream FortiGate to allow proper communication and management.
* Enable Security Fabric/Fortitelemetry on the receiving interface of the upstream FortiGate: The upstream FortiGate must have the Security Fabric or Fortitelemetry enabled on the interface that receives the communication from the downstream FortiGate. This enables proper data exchange and monitoring within the Security Fabric.
