Configuring Port-based Traffic Segmentation
– 801 –
only be forwarded to, and from, the designated uplink port(s). Data
cannot pass between downlink ports in the same segmented group, nor
to ports which do not belong to the same group.
â—† Any port can be defined as an uplink port or downlink port, but cannot
be configured to serve both roles.
â—† Traffic segmentation and normal VLANs can exist simultaneously within
the same switch. Traffic may pass freely between uplink ports in
segmented groups and ports in normal VLANs.
â—† Enter the traffic-segmentation command without any parameters to
enable traffic segmentation. Then set the interface members for
segmented groups.
â—† Enter no traffic-segmentation to disable traffic segmentation and
clear the configuration settings for segmented groups.
EXAMPLE

uplink and ports 5-8 as downlinks.
