Thank you for your feedback

You can use the TWAMP Reflector configuration step to define a configuration job that does one of the following tasks:

Configure a Skylight element to act as a TWAMP reflector
Configure Skylight sensor: module or Skylight sensor: SFP compute modules (remote devices of a Skylight sensor: control) to act as TWAMP reflectors.

To set up a TWAMP Reflector configuration job

Access the page Commission ▶ Jobs.
Set all common configuration job settings, as described in "Creating Configuration Jobs in GUI Mode" and "Creating Configuration Jobs Using Data Sets". If you check ME reference data set enabled checkbox, see the table TWAMP Reflector tab - Dataset section below for information about the fields.
Select TWAMP Reflector in the left pane. The TWAMP Reflector tab is displayed.
Complete the fields as explained in the table below.
If the element you are configuring is a sensor: control, you can add rows to set up more of its Skylight sensor: modules as TWAMP reflectors, click the Add button, or select a row in the table and click the Duplicate button. Complete the fields as required.
Click Apply, then click Close.
Click the Refresh button to refresh the user interface.

General

Parameter	Description
Enable	Enables or disables reflection on the element (being configured) on the UDP port specified.
UDP port	Specifies the UDP port to use for reflection. Range: 600 to 65,535 Default value: 6,000
IP match	Should always be enabled. When IP match is enabled, the TWAMP reflector only reflects packets sent to its IP address and UDP port.
Segmented	Should always be disabled. If disabled, the TWAMP packets will be not be forwarded beyond the reflector (the end of the first segment).
Mode	Possible values: stateful - Only the first 16 TWAMP flows are reflected, according to their session information (SRC IP, SRC UDP PORT). stateless - All TWAMP flows are reflected without knowledge of the sessions (SRC IP, SRC UDP PORT). hybrid - The first 16 TWAMP flows have a stateful session. All other flows are reflected without session knowledge. When one of the 16 flows is no longer used (because it stops receiving new frames), one of the stateless flows automatically becomes stateful. If a TWAMP stateful session ages out, one of the TWAMP stateless sessions will automatically become stateful.
Session ID	TWAMP stateful session number (1 to 16).
Filter Type	Select a filter type from the drop-down list, either IPv4 or IPv6.
Filter Name	Unique name used to identify the filter.
