Configuring the WAN

A Field Office Example

Again, Leo fills out the advanced DHCP screen as he did for the two previous subnets. Leo clicks the OK button on the Advanced DHCP Server window, then the Apply button on the subnet window.

The next step is to configure the WAN interface.

Configuring the WAN

Next Leo configures the WS 2000 WAN interface. This interface connects the WS 2000 switch to the VPN appliance and, through that appliance, to the Internet.

Leo enables the WAN interface, but leaves the DHCP client option disabled. Instead of using DHCP to get address information for the switch, he enters the permanent information that he previously obtained from the corporate network administrator. He enters the IP address for the switch, the gateway address (in this case, the VPN appliance), and the IP addresses of the corporate primary and secondary DNS servers.

The corporation has a frame relay link between this office, the corporate network and the Internet. If the connection to the WAN had been through a DSL link, the account information would be entered in the PPP over Ethernet section on the bottom of this screen. Since it will not be needed, Leo makes sure that PPP Over Ethernet Enable checkbox is not checked.

All Rights ReservedRetail Use Cases Configuring the Cafe Subnet Clarisa clicks Advanced DHCP Server and enters the DNS server IP addresses. The Default Gateway is fine. However, Clarisa expects the cafe patrons to come and go frequently, so she reduces the IP address lease time to 1800 seconds. This means that a DHCP client mobile unit will give up its IP address if it is inactive on the network for more than half an hour. This seems about right for the usage patterns that she expects for the cafe. If she gets complaints, she will bump it to an hour Configuring the WAN Interface Configuring Network Address Translation NAT After she makes this selection a new button appears, labeled 1 to Many Mappings.

A Field Office ExampleThe Plan Each WS 2000 WLAN has exactly one security policy, where a security policy is defined as a user authentication method and a data encryption method. Because each WLAN can have one and only one security policy, WLAN configuration is usually defined by the security needs of the installation. If two groups of users require different security policies, then they must associate to the WS 2000 through different WLANs. See the Retail Use Case for an example of an installation where different security needs drive the need for separate WLANsContacting the Wireless Switch Configuring the System SettingsTo begin configuration of the switch, Leo sets up a communication link to the switch. Leo starts with a direct network link between his laptop and the switch, plugging the cable into one of the local, non-WAN, ports. The switch defaults to having all the LAN ports on the first subnet and that subnet having an IP address of 192.168.0.1. So, as far as this connection is concerned, the switch comes up with an initial IP address of 192.168.0.1. He sets his laptop to have an IP address of 192.168.0.2 and a netmask of 255.255.255.0. He also sets the gateway IP address to be 192.168.0.1, the WS 2000’s IP address Leo launches his web browser and enters “http//192.168.0.1/” as the URL. He logs in using “admin” for the username and “symbol” as the password Entering the Basic System SettingsSetting Access Control Leo then changes the switch passwords from the default to something relatively secure, something with letters, numbers, and punctuation marks in it Configuring the Engineering LAN Configuring the LANHe also selects the option This interface is a DHCP server. Choosing this DHCP option means that the switch will pick IP addresses from the Address Assignment Range and assign them to network clients on this subnet, as needed WS 2000 Wireless Switch 1.0 Date of last Revision March Copyright 2004 Symbol Technologies, Inc.
