CONFIGURING PORT-BASED TRAFFIC SEGMENTATION
If tighter security is required for passing traffic from different clients
through downlink ports on the local network and over uplink ports to the
service provider, port-based traffic segmentation can be used to isolate
traffic for individual clients.
traffic-segmentation This command enables traffic segmentation globally, or configures the
uplink and down-link ports for a segmented group of ports. Use the no
form to disable traffic segmentation globally.
SYNTAX
[no] traffic-segmentation [uplink interface-list
downlink interface-list]
uplink – Specifies an uplink interface.
downlink – Specifies a downlink interface.
