Configuring Uplink and Downlink Ports
Use the Interface > Traffic Segmentation (Configure Session) page to assign the downlink and uplink ports to use in the segmented
group. Ports designated as downlink ports can not communicate with any other ports on the switch except for the uplink ports.
Uplink ports can communicate with any other ports on the switch and with any designated downlink ports.
Command Usage

When traffic segmentation is enabled, the forwarding state for the uplink and downlink ports assigned to different client
sessions is shown below.
* - The forwarding state for uplink-to-uplink ports is configured on the Configure Global page.

When traffic segmentation is disabled, all ports operate in normal forwarding mode based on the settings specified by other
functions such as VLANs and spanning tree protocol.

A port cannot be configured in both an uplink and downlink list.

A port can only be assigned to one traffic-segmentation session.

A downlink port can only communicate with an uplink port in the same session. Therefore, if an uplink port is not
configured for a session, the assigned downlink ports will not be able to communicate with any other ports.

If a downlink port is not configured for the session, the assigned uplink ports will operate as normal ports.
The following table lists the options on this page:
