Configuring Uplink And Downlink Ports; Table 9: Traffic Segmentation Forwarding - Edge-Core ECS4510-12PD Web Management Manual

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.

* The forwarding state for uplink-to-uplink ports is configured on the Configure Global
page (see page 131).
◆
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)
◆
Direction – Adds an interface to the segmented group by setting the direction
to uplink or downlink. (Default: Uplink)
