Fortinet NSE7_NST-7.2 Exam With Confidence Using Practice Dumps

Diagnose NPU NP6 Port-list Disable Command:

Thediagnose npu np6 port-list disablecommand disables specific ports on the NP6 processor. This can help in cases where you need to analyze traffic and the hardware offloading is interfering.

Command:diagnose npu np6 port-list disable 5 17(as shown in Option A).

Diagnose NPU NP6 Fastpath Disable Command:

Disabling the fastpath feature on NP6 can also allow for better visibility into the traffic as it bypasses hardware acceleration, which might obscure traffic details.

Command:diagnose npu np6 fastpath disable 0(as shown in Option C).

The session table entry provided shows detailed information about a specific network session passing through the FortiGate device. From the session details, we can see that the session has various attributes such as state, protocol, policy, and inspection details.

The session state (proto_state=11) indicates that the session is being actively processed and inspected.

Thenpd_state=00000000suggests that the session is being handled by the CPU rather than offloaded to a Network Processor (NP).

The session is marked for security profile inspection, evident from the detailed byte/packet counts and other session parameters.

From these indicators, it's clear that FortiGate is using its CPU to perform security profile inspection on this session rather than simply forwarding the traffic without inspection or relying solely on IPS inspection.

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).
