Configuring Port-based Traffic Segmentation
– 1158 –
◆ 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.
◆ Enter the traffic-segmentation command without any parameters to
enable traffic segmentation. Then set the interface members for
segmented groups using the traffic-segmentation uplink/downlink
command.
◆ Enter no traffic-segmentation to disable traffic segmentation and
clear the configuration settings for segmented groups.
EXAMPLE
