82 Switch Feature Overview
Virtual Local Area Network Supported Features
For information about configuring VLAN features see "VLANs" on page 737.
VLAN Support
VLANs are collections of switching ports that comprise a single broadcast
domain. Incoming packets are classified as belonging to a VLAN based on
either the VLAN tag or a combination of the ingress port and packet contents.
Transmitted packets are forwarded tagged or untagged based upon the
configuration of the egress port. The Dell EMC 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 configuration and the VLAN tag, if present. 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.
