VLAN (Virtual LANs) are software defined groups of interfaces that communicate within one protocol seemingly as if they are on the same wire even though they are spread out on different LAN segments. Standard interface attributes can be applied to VLANs.
VLANs can be created on one, two or all ports. VLANs can be included per unit, per device, per stack, or in any combination of logical connections. Broadcast and multicast traffic is transmitted within the same VLAN that created it, thereby saving bandwidth and making the network more efficient. The NMS has default VLANs that already exist and initially do not contain any ports.
The VLANs can be different protocols:
IP VLAN - If IP is selected, either True or False for the Auto Config parameter. If Auto Config is enabled (True) the device will automatically detect and add ports to the VLAN in accordance with incoming broadcasts and ARP requests. This means that a network device can be moved to a different device port and remain in the same VLAN.
Note: IP VLANs are automatically assigned a MAC address.
Other VLAN - The "Other" VLAN is a "super-VLAN" that includes all protocols for which VLANs have not been defined. However, it does not include IP. "Other" can be used to quickly configure the device as a full bridge.
