Configuring the Printer WLAN

Retail Use Cases

She clicks the Apply button to save her choices.

Clarisa goes to the left menu and clicks the “+” to the left of the Cafe WLAN node. A menu item labeled Cafe Security appears and Clarisa selects it.

She confirms that the Cafe Security screen shows that no authentication and no encryption methods.

Configuring the Printer WLAN

For the printer WLAN, Clarisa makes the following selections:

Name	Printer
ESSID	CCC-Printer

Subnet	Printsn

Disallow MU to MU Communication	Yes

Use Voice Prioritization	No

Answer Broadcast ESS	No

There will not be any VoIP devices in the store, therefore voice prioritization will not be useful. The wireless printers will never need to communicate with each other directly. MU to MU communications can be safely disallowed. Allowing Answer Broadcast ESS is a way to allow mobile units that are not configured with the network ESSID to associate with the WLAN. She knows that she will configure all of the mobile units on this WLAN with the correct ESSID, so she disallows this option, potentially keeping a cafe customer out of the printer WLAN.

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 Example BackgroundEach 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 WLANs The PlanContacting 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 Entering the Basic System Settings 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 passwordSetting 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 LAN Configuring the Engineering 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.
