VLANs Overview

Setting up VLANs on the switch eases many time-consuming tasks of network administration while increasing efficiency in network operations.

Note

The software supports using IPv6 addresses, in addition to IPv4 addresses. You can configure the VLAN with an IPv4 address, IPv6 address, or both. See IPv6 Unicast Routing for complete information on using IPv6 addresses.

The term VLAN is used to refer to a collection of devices that communicate as if they were on the same physical LAN.

Note

ExtremeXOS supports only 4,092 user-configurable VLANs. (VLAN 1 is the default VLAN, and 4,095 is the management VLAN, and you may not configure them.

Any set of ports (including all ports on the switch) is considered a VLAN. LAN segments are not restricted by the hardware that physically connects them. The segments are defined by flexible user groups that you create with the command line interface (CLI).

Note

The system switches traffic within each VLAN using the Ethernet MAC address. The system routes traffic between two VLANs using the IP addresses.
