30 Switching Configuration
• The IP-subnet Based VLAN feature lets you map IP addresses to VLANs by specifying a source IP
address, network mask, and the desired VLAN ID.
• The MAC-based VLAN feature let packets originating from end stations become part of a VLAN
according to source MAC address. To configure the feature, you specify a source MAC address and a
VLAN ID.
The Private Edge VLAN feature lets you set protection between ports located on the switch. This means
that a protected port cannot forward traffic to another protected port on the same switch.
The feature does not provide protection between ports located on different switches.
For information about authenticated, unauthenticated, and guest VLANs, see "802.1X Authentication
and VLANs" on page 109.
VLAN Configuration Example
The diagram in this section shows a switch with four ports configured to handle the traffic for two
VLANs. Port 1/g18 handles traffic for both VLANs, while port 1/g17 is a member of VLAN 2 only, and
ports 1/g19 and 1/g20 are members of VLAN 3 only. The script following the diagram shows the
commands you would use to configure the switch as shown in the diagram.
