Configure a Private VLAN
A private VLAN contains switch ports that cannot communicate with each other, but can 
access another network. These ports are called private ports. Each private VLAN contains 
one or more private ports and a single uplink port or uplink aggregation group. Note that all 
traffic between private ports is blocked at all Layers, not just Layer 2 traffic, but also traffic 
such as FTP, HTTP, and Telnet.
To configure a private VLAN type:
1. 
Prepare your computer with a static IP address in the 169.254.100.0 subnet, for 
example, 169.254.100.201.
2. 
Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on 
the switch.
