82 Switch Feature Overview
Virtual Local Area Network Supported Features
For information about configuring VLAN features see "VLANs " on page 701.
VLAN Support
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 Dell
Networking N-Series switches are in full compliance with IEEE 802.1Q
VLAN tagging.
Port-Based VLANs
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.
IP Subnet-based VLAN
This feature allows incoming untagged packets to be assigned to a VLAN and
traffic class based on the source IP address of the packet.
MAC-based VLAN
This feature allows incoming untagged packets to be assigned to a VLAN and
traffic class based on the source MAC address of the packet.
IEEE 802.1v Protocol-Based VLANs
VLAN classification rules are defined on data-link layer (layer-2) protocol
identification. Protocol-based VLANs are used for isolating layer-2 traffic.
GARP and GVRP Support
NOTE: GARP, GVRP, and GMRP are not available when running the
AGGREGATION ROUTER image.
