Fortinet NSE5_FSW_AD-7.6 Exam - Topic 2 Question 9 Discussion

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 appropriateshoworgetcommands 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.
