Private Edge VLANs

Use the Private Edge VLAN feature to prevent ports on the switch from forwarding traffic to each other
even if they are on the same VLAN.
• Protected ports cannot forward traffic to other protected ports in the same group, even if they have the
same VLAN membership. Protected ports can forward traffic to unprotected ports.
• Unprotected ports can forward traffic to both protected and unprotected ports.
You can also configure groups of protected ports, but unprotected ports are independent and cannot be
added to a group. Each group's configuration consists of a name and a mask of ports. A port can belong
to only one set of protected ports, but an unprotected port can be added to a group as a protected port.
The group name is configurable by the network administrator.
Use the switchport protected command to designate a port as protected. Use the show
switchport protected command to display a listing of the protected ports.
