VLANs
This page allows you to create and delete VLANs (Virtual LANs) and to change the VLAN membership and
behavior of individual ports. VLANs are powerful, but can be difficult to set up properly. Each row of the table
corresponds to one port or trunk; trunked ports cannot be configured individually.
Introduction to VLANs
VLANs are logical partitions of the physical LAN. You can use VLANs to increase network performance or
improve internal network security. If the network has adequate performance and security for your current
needs, it is recommended that you leave the VLAN settings in the default configuration. The default
configuration is as follows:
All ports are members of VLAN 1
The switch management interface is on VLAN 1
All ports have a Port VLAN ID (PVID) of 1
All ports can send and receive both VLAN-tagged and untagged packets (that is, they are hybrid
ports)
In the default configuration, any port is able to send traffic to any other port and a PC connected to any port
will be able to access the management interface. Broadcast traffic, for example, will be flooded to all ports on
the NXA-ENET8POE.
The NXA-ENET8POE supports up to 64 VLANs. A Virtual LAN is a collection of network nodes that share
the same collision domain regardless of their physical location or connection point in the network. The device
supports tagged VLANs based on the IEEE 802.1Q standard. Ports can be manually assigned to a specific set
of VLANs. This allows the NXA-ENET8POE to restrict traffic to the VLAN groups to which a user has been
assigned. By segmenting your network into VLANs, you can:
Eliminate broadcast storms which severely degrade performance in a flat network.
Simplify network management for node changes/moves by remotely configuring VLAN
membership for any port, rather than having to manually change the network connection.
Provide data security by restricting all traffic to the originating VLAN.
