For information about configuring VLAN features see "Configuring VLANs"

on page 575.

VLANs are collections of switching ports that comprise a single broadcast

domain. Packets are classified as belonging to a VLAN based on either the

VLAN tag or a combination of the ingress port and packet contents. Packets

sharing common attributes can be groups in the same VLAN. The

PowerConnect M6220, M6348, M8024, and M8024-k switches are in full

compliance with IEEE 802.1Q VLAN tagging.

Port-based VLANs classify incoming packets to VLANs based on their ingress

port. When a port uses 802.1X port authentication, packets can be assigned

to a VLAN based on the result of the 802.1X authentication a client uses

when it accesses the switch. This feature is useful for assigning traffic to

Guest VLANs or Voice VLANs.

This feature allows incoming untagged packets to be assigned to a VLAN and

traffic class based on the source IP address of the packet.

This feature allows incoming untagged packets to be assigned to a VLAN and

traffic class based on the source MAC address of the packet.

VLAN classification rules are defined on data-link layer (Layer 2) protocol

identification. Protocol-based VLANs are used for isolating Layer 2 traffic for

differing Layer 3 protocols.
