Private VLAN Connections

This switch can be configured for up to 255 VLANs. Also, it supports
Private VLANs that allow traffic isolation for ports within a VLAN and
restrict forwarding to only the designated uplink ports.
Each subscriber downlink port (or ports) can be configured into its own
Private VLAN, so that traffic is forwarded only to and from the switch's
uplink ports. This provides robust port-based security for each subscriber.
Furthermore, the switch can control the bandwidth of downlink
connections using traffic rate limiting. Each fiber port downlink can be
limited to values from 1 Mbps to 100 Mbps depending on the needs of the
individual user. The service provider can then charge subscribers
according to the bandwidth provided.
