Setting the Ethernet (Wired) Interface

Ethernet (Wired) Settings describe the configuration of your Ethernet local area network (LAN).


Note	The Ethernet Settings, including guest access, are not shared across the cluster. These settings must be configured individually on the Administration pages for each access point. To get to the Administration pages for an access point that is a member of the current cluster, click on its IP Address link on the Cluster > Access Points page of the current AP. For more information about which settings are shared by the cluster and which are not, see Which Settings are Shared as Part of the Cluster Configuration and Which Are Not?.

Setting the DNS Name


Field	Description
DNS Name	Enter the DNS name for the access point in the text box. This is the host name. It may be provided by your ISP or network administrator, or you can provide your own. The rules for system names are: This name can be up to 20 characters long. Only letters, numbers and dashes are allowed. The name must start with a letter and end with either a letter or a number.

Enabling or Disabling Guest Access

You can provide controlled guest access over an isolated network and a secure internal LAN on the same U.S. Robotics Professional Access Point.

Configuring an Internal LAN and a Guest Network

A Local Area Network (LAN) is a communications network covering a limited area, for example, one floor of a building. A LAN connects multiple computers and other network devices like storage and printers.

Ethernet is the most common technology implementing a LAN. Wi-Fi (IEEE) is another very popular LAN technology.

The U.S. Robotics Professional Access Point allows you to configure two different LANs on the same access point: one for a secure internal LAN and another for a public guest network with no security and little or no access to internal resources. To configure these networks, you need to provide both Wireless and Ethernet (Wired) settings.

Information on how to configure the Ethernet (Wired) settings is provided in the sections below.

(For information on how to configure the Wireless settings, see Setting the Wireless Interface. For an overview of how to set up the Guest interface, see Setting up Guest Access.)

Enabling or Disabling Guest Access

The U.S. Robotics Professional Access Point ships with the Guest Access feature disabled by default. If you want to provide guest access on your AP, enable Guest access on the Ethernet (Wired) Settings tab.


Field	Description
Guest Access	By default, the U.S. Robotics Professional Access Point ships with Guest Access disabled. To enable Guest Access, click Enabled. To disable Guest Access, click Disabled.

Specifying a Physical or Virtual Guest Network

If you enable Guest Access, you must choose a method of representing both an "Internal" and "Guest Network" on this access point. There are two ways of doing this: (1) physically, by connecting the two LAN ports on the access point to different networks with two different cables; one to the internal LAN and another to a guest network, or (2) virtually, by connecting the LAN port on the access point to a tagged port on a VLAN capable switch and then defining two different Virtual LANs on this Administration page. (For more information, see Setting up Guest Access.)

Choose either physically separate or virtually separate internal and guest LANs as described below.


Field	Description
Guest Access	Select Enabled to enable Guest Access. (If you choose this option, you must select whether to use physically separate networks or VLANs on the next setting "For Guest access, use", and then provide details on VLAN or Wired setting for the Guest Network on the rest of the page.) Select Disabled to disable Guest Access
For Guest access, use	Specify either a physically or virtually separate guest network on this access point: If you connected this access point to two separate networks for a "physically secure" solution, then choose Ethernet Port 2 from the drop-down menu to set up your Guest network on the second Ethernet port. If the access point is using only one physical connection to your internal LAN (extra port is not in use), then choose VLAN on Ethernet Port 1 from the drop-down menu. This will enable the "VLAN" settings where you must provide a VLAN ID. See also Configuring Guest Interface Ethernet (Wired) Settings. Caution: If you reconfigure the Guest and Internal interfaces to use VLANs, you may lose connectivity to the access point. First, be sure to verify that the switch and DHCP server you are using can support VLANs per the IEEE 802.1Q standard. After configuring the VLAN on the Advanced > Ethernet (Wired) Settings page, physically reconnect the Ethernet cable on the switch to the tagged packet (VLAN) port. Then, re-connect via the Administration Web pages to the new IP address. (If necessary, check with the infrastructure support administrator regarding the VLAN and DHCP configurations.)

Enabling or Disabling Virtual Wireless Networks on the AP

If you want to configure the Internal network as a VLAN (whether or not you have a Guest network configured), you can enable "Virtual Wireless Networks" on the access point.

You must enable this feature if you want to configure additional virtual networks on VLANs on the Advanced > Virtual Wireless Networks tab as described in Configuring Virtual Wireless Networks.


Field	Description
Virtual Wireless Networks (Using VLANs on Ethernet Port 1)	Select Enabled to enable VLANs for the Internal network and for additional networks. (If you choose this option, you can run the Internal network on a VLAN whether or not you have Guest Access configured and you can set up additional networks on VLANs using the Advanced > Virtual Wireless Networks tab as described in Configuring Virtual Wireless Networks.) Select Disabled to disable the VLAN for the Internal network, and for any additional virtual networks on this access point.

Configuring Internal Interface Ethernet Settings

To configure Ethernet (Wired) settings for the Internal LAN, fill in the fields as described below.


Field	Description
MAC Address	Shows the MAC address for the Internal interface for the Ethernet port on this access point. This is a read-only field that you cannot change.
VLAN ID	If you choose to configure Internal and Guest networks by "VLANs", this field will be enabled. Provide a number between 1 and 4094 for the Internal VLAN. This will cause the access point to send DHCP requests with the VLAN tag. The switch and the DHCP server must support VLAN IEEE 802.1Q frames. The access point must be able to reach the DHCP server. Check with the Administrator regarding the VLAN and DHCP configurations.
Connection Type	You can select "DHCP" or "Static IP". The Dynamic Host Configuration Protocol (DHCP) is a protocol specifying how a centralized server can provide network configuration information to devices on the network. A DHCP server "offers" a "lease" to the client system. The information supplied includes the IP addresses and netmask plus the address of its DNS servers and gateway. Static IP indicates that all network settings are provided manually. You must provide the IP address for the U.S. Robotics Professional Access Point, its subnet mask, the IP address of the default gateway, and the IP address of at least one DNS nameserver. If you select "DHCP", the U.S. Robotics Professional Access Point will acquire its IP Address, subnet mask, and DNS and gateway information from the DHCP Servers. Otherwise, if you select "Static IP", fill in the items described in "Static IP Settings." Caution: If you do not have a DHCP server on the Internal network and do not plan to use one, the first thing you must do after bringing up the AP is change the Connection Type from DHCP to Static IP. When you change the Connection Type to Static IP, you can either assign a new Static IP Address to the AP or continue using the default address. We recommend assigning a new address so that if later you bring up another U.S. Robotics Professional Access Point on the same network, the IP addresses for the two APs will be unique. If you need to recover the default Static IP address, you can do so by resetting the AP to the factory defaults as described in Resetting the Configuration.
Static IP Address	If you chose "Static IP" as the Connection Type, these fields will be enabled. Enter the Static IP Address in the text boxes.
Subnet Mask	Enter the Subnet Mask in the text boxes. You must obtain this information from your ISP or network administrator.
Default Gateway	Enter the Default Gateway in the text boxes.
DNS Nameservers	The Domain Name Service (DNS) is a system that resolves the descriptive name (domainname) of a network resource (for example, `www.usr.com`) to its numeric IP address (for example, `66.93.138.219`). A DNS server is called a Nameserver. There are usually two Nameservers; a Primary Nameserver and a Secondary Nameserver. You can choose Dynamic or Manual mode. If you choose Manual, you should assign static IP addresses manually. If you choose Dynamic, the IP addresses for the DNS servers will be assigned automatically via DHCP. (This option is only available if you specified DHCP for the Connection Type.)

Configuring Guest Interface Ethernet (Wired) Settings

To configure Ethernet (Wired) Settings for the "Guest" interface, fill in the fields as described below.


Field	Description
MAC Address	Shows the MAC address for the Guest interface for the Ethernet port on this access point. This is a read-only field that you cannot change.
VLAN ID	If you choose to configure Internal and Guest networks by "VLANs", this field will be enabled. Provide a number between 1 and 4094 for the Guest VLAN.
Subnet	Shows the subnetwork address for the Guest interface. For example, 192.168.1.0.
