[sreddi]

Description
For communicating timing precision between two ends, PTP transparent clock mode can be enabled to measure and adjust for packet delay.

It is supported on the following FortiSwitch:
3032E, 3032D, 1048E, 5xxD series, 4xxE series, 424D, 224E, and 224D.

This article describes how o configure FortiSwitch PTP settings and policies.

Scope

Solution
On the FortiGate which is managing the compatible FortiSwitch, switch controller PTP settings and policies can be configured per VDOM.
A PTP policy can also be selected for each FortiSwitch port.

To configure the switch controller PTP settings.

# config switch-controller ptp settings
    set mode {default | transparent-e2e | transparent-p2p}
end

default: Disable the PTP function (Default) packets are forwarded with no action .
transparent-e2e: Enable end-to-end transparent clock.
transparent-p2p: Enable Peer-to-peer transparent clock.

To configure a switch controller PTP policy.

# config switch-controller ptp policy
    edit "default"
        set status enable
    next
end

To set the PTP policy on a switch port.

# config switch-controller managed-switch
    edit "S524D00000000000"
        # config ports
            edit "port1"
                set ptp-policy default
            next
        end
    next
end
