Configuring Port-based Traffic Segmentation
traffic-segmentation
This command enables traffic segmentation. Use the no form to disable traffic segmentation.
Syntax
[no] traffic-segmentation
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
•
Traffic segmentation provides port-based security and isolation between ports within the VLAN.
Data traffic on the downlink ports can 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.
•
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.
•
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.
