Fortinet NSE6_FSW-7.2 Exam Dumps

To enable access to the FortiSwitch management interface from the network, certain configuration adjustments need to be made, particularly considering the VLAN settings displayed in the exhibit:

Adding port24 native VLAN to the allowed VLANs on internal (Option A): The management VLAN (VLAN 4094 in this case, as it is set as the native VLAN on the 'internal' interface of the FortiSwitch) must be included in the allowed VLANs on the interface that provides management connectivity. Since port24 is set with a different native VLAN (VLAN 100), VLAN 4094 (the management VLAN) should be allowed through to ensure connectivity.

Allow VLAN ID 4094 on port24 if management traffic is tagged (Option C): Management traffic is tagged on VLAN 4094. Since port24 is connected to the network and serves as an uplink, allowing VLAN 4094 ensures that management traffic can reach the management interface of the FortiSwitch through this port.

The changes align with Fortinet's best practices for setting up management VLANs and ensuring they are permitted on the relevant switch ports for proper management traffic flow.

When loop guard is enabled on port1 and port2 configured with the same native VLAN (VLAN 10), there are specific scenarios under which port1 can be shut down due to loop guard operation:

A . port1 was shut down by loop guard protection. Loop guard is a specific feature used in network environments to prevent alternative or redundant loops. When loop guard is active, it can shut down a port if it stops receiving BPDU (Bridge Protocol Data Units) on a port that is expected to receive them, assuming a loop or link failure and putting the port into an inconsistent state to prevent potential loops.

B . STP triggered a loop and applied loop guard protection on port1. If the Spanning Tree Protocol (STP) detects a loop or loss of BPDU transmissions while loop guard is enabled, it will proactively shut down the port to prevent network instability or a broadcast storm. This is an essential function of loop guard within the context of STP, providing additional protection against topology changes that could introduce loops.

Additional details about loop guard functionality and STP interaction can be found in the FortiSwitch administration guides, accessible via Fortinet Documentation.

The information in the 'Native VLAN' column for port23 on the FortiSwitch indicates that a standalone switch is connected to it. This is because the column displays '$424MPTF20000027,' which matches the format of a Fortinet device serial number.

Here's a breakdown of the evidence in the image:

Native VLAN: The 'Native VLAN' column typically displays the VLAN ID for untagged traffic on a trunk port. However, in this case, it shows a serial number format ('$424MPTF20000027').

No Trunk Information: The 'Trunk' column is blank for port23, indicating it's not configured as a trunk member.

Other Ports: Port1 and port2 show 'default' in the 'Native VLAN' column, which is the expected behavior for access ports.

Fortinet FortiSwitch devices typically don't display the serial number of adjacent FortiSwitch devices in the 'Native VLAN' column. This column is reserved for VLAN information on trunk ports.

To cause endpoints to exchange PoE information and negotiate power with the managed FortiSwitch via LLDP, you should configure the LLDP profile to include power management in the advertised LLDP-MED TLVs. Here are the steps:

Access the LLDP Profile Configuration: Start by entering the LLDP profile configuration mode with the command:

config switch-controller lldp-profile

edit 'LLDP-PROFILE'

Enable MED-TLVs: Ensure that MED-TLVs (Media Endpoint Discovery TLVs) are enabled. These TLVs are used for extended discovery relating to network policies, including PoE, and are essential for PoE negotiation. They include power management which is crucial for the negotiation of PoE parameters between devices. The command to ensure network policies are set might look like:

set med-tlvs network-policy

Add Power Management TLV: Specifically add or ensure the power management TLV is part of the configuration. This will advertise the PoE capabilities and requirements, enabling dynamic power allocation between the FortiSwitch and the connected devices (like VoIP phones or wireless access points). This can typically be done within the network-policy settings:

config med-network-policy

edit

set poe-capability

next

end

Save and Apply Changes: Exit the configuration blocks properly ensuring changes are saved:

End

Verify Configuration: It's always good practice to verify that your configurations have been applied correctly. Use the appropriate show or get commands to review the LLDP profile settings.

By adding the power management as part of LLDP-MED TLVs, the FortiSwitch will be able to communicate its power requirements and capabilities to the endpoints, thereby facilitating a dynamic power negotiation that is crucial for efficient PoE utilization.
