Graphical User Interface

Use the following screens to perform the same configuration using the Graphical User Interface:

zSwitching -->VLAN--> Configuration. To create the VLANs and specify port participa- tion.

zSwitching --> VLAN --> Port Configuration. To specify the handling of untagged frames on receipt, and whether frames will be transmitted tagged or untagged.

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.

zProtected 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 in their group.

zUnprotected ports can forward traffic to both protected and unprotected ports.

You can also configure groups of protected ports. 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 if a port is unprotected in one group it can be protected in another group.

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.
