Traffic Segmentation
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.
•
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.
Parameters
These parameters are displayed:
•
Session ID – Traffic segmentation session. (Range: 1-4)
