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 client sessions.
Traffic belonging to each client is isolated to the allocated downlink ports. But the switch
can be configured to either isolate traffic passing across a client’s allocated uplink ports
from the uplink ports assigned to other clients, or to forward traffic through the uplink ports
used by other clients, allowing different clients to share access to their uplink ports where
security is less likely to be compromised.
This section describes commands used to configure traffic segmentation.
pvlan
This command enables port-based traffic segmentation. Use the no form to disable this
feature.
