Private Edge Vlans - Dell PowerConnect M6348 Configuration Manual

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.
