Configuring a VLAN

STEP 1 To add a new VLAN, click Add. To modify the settings for a VLAN, click the Edit (pencil) icon.

Other options: To delete a VLAN, click the Delete (x) icon. The default VLANs cannot be deleted.

STEP 2 In the Basic Settings tab, enter the following information:

•Name: Enter the name for the VLAN.

•VLAN ID: Enter a unique identification number for the VLAN, which can be any number from 3 to 4089. The VLAN ID 1 is reserved for the DEFAULT VLAN and the VLAN ID 2 is reserved for the GUEST VLAN.

•IP Address: Enter the subnet IP address for the VLAN.

•Netmask: Enter the subnet mask for the VLAN.

•Spanning Tree: Check this box to enable the Spanning Tree feature to determine if there are loops in the network topology. The Spanning Tree Protocol (STP) is a link layer network protocol that ensures a loop-free topology for any bridged LAN. The STP is used to prevent bridge loops and to ensure broadcast radiation.

•Voice VLAN: Check the box if you want voice applications to use this VLAN.

•Port: Assign the LAN ports to the VLAN. Traffic through the selected LAN ports is directed to the VLAN. All available ports including the dedicated LAN ports and the configurable ports appear in the Port list.

Choose the ports from the Port list and click Access to add them to the Member list and set the selected ports as the Access mode. Alternatively, you can choose the ports from the Port list and click Trunk to add them to the Member list and set the selected ports as the Trunk mode.

NOTE: This setting will change the port type and access mode of the selected physical ports. For example, choose a port that was set as a DMZ port and add it to the Member list. The DMZ port will be configured as a LAN port. Changing the port type will wipe out all configuration relative to the physical port.

•Zone: Choose the zone to which the VLAN is mapped. By default, the DEFAULT VLAN is mapped to the LAN zone, the GUEST VLAN is mapped to the GUEST zone, and the VOICE VLAN is mapped to the VOICE zone. You can click the Create Zone link to view, edit, or add the zones on the security appliance.
