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.

SAGE

When traffic segmentation is enabled, the forwarding state for the

uplink and downlink ports assigned to different client sessions is shown

below.

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.

direction to uplink or downlink. (Default: None)
