[preart]

Fortigate 400E (FortiOS 7.0)

DHCP RELAY configured

How can I disable the addition of Option 82 Suboption: (1) Agent Circuit ID to forwarded DHCP requests?

Found decision in  FortiGate / FortiOS 7.0.0 Administration Guide: set dhcp-relay-agent-option disable:

To configure the DHCP relay agent option using the CLI:

config system interface
    edit <interface>
        set vdom root
        set dhcp-relay-service enable
        set dhcp-relay-ip <ip>
        set dhcp-relay-agent-option disable
        set vlanid <id>
    next
end
