XG Series User's Guide Chapter 4 Switch Functions and their ConfigurationVLAN744.6 VLANVLAN (Virtual LAN) is a technology that divides a single network into virtually separated networks.VLANs are separate logical networks within one physical network. A VLAN capable switch can change and define newLAN network configurations without changing physical cable connections. This creates a flexible and extensible networksystem.The device provides for port-based or Tag-based (IEEE802.1Q) VLANs.4.6.1 Port-Based VLANPort-based VLAN is a method for configuring VLAN membership on a port basis. Forwarding is based on the destinationMAC addresses and related port.To configure a port-based VLAN, carry out the following procedures in "admin" Operation mode.Command TaskXG2600# configure Switch to Configuration mode.XG2600(config)# ether 1-3 vlan untag 10 Set the default port VLAN ID 10 for port 1-3.XG2600(config)# ether 5-7 vlan untag 20 Set the default port VLAN ID 20 for port 5-7.XG2600(config)# ether 4,8 vlan untag 30 Set the default port VLAN ID 30 for port 4,8.XG2600(config)# commit Apply the configuration.XG2600(config)# save Save the configuration.XG2600(config)# exit Switch to Operation mode.Segment 1 (VLAN10)Segment 2 (VLAN20)Segment 3 (VLAN30)1 2 3 45 6 7 8VLAN10 consistsof Port 1, 2, 3VLAN20 consistsof Port 5, 6, 7 VLAN30 consistsof port 4, 8Port Base VLAN
