Traffic Segmentation
Figure 71: Enabling 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.
Table 10: Traffic Segmentation Forwarding

* The forwarding state for uplink-to-uplink ports is configured on the Configure Global
page (see
page 143 ).
◆ 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.
