WS 2000 Wireless Switch System Reference Guide2-8
• The two DNS Server fields specify DNS addresses of servers that can translate domain names, such as
www.symbol.com, into IP addresses that the network uses when passing information. The Secondary DNS Server
acts as a backup to the Primary DNS Server when the primary server is not responding.
Setting Up Point-to-Point over Ethernet (PPPoE) Communication
PPPoE provides the ability to connect a network of hosts through a simple device to a remote access concentrator. Many DSL
providers require that their clients communicate using this protocol. The facility allows the ISP to control access, billing, and
type of service provided to clients on a per-user or per-site basis. Check with the network administrator or ISP to determine
whether to enable this feature, and, if so, find out the username and password required for authentication.
1. Check Enable in the PPP over Ethernet area to enable the PPPoE protocol for high-speed connections.
2. Enter the Username and Password required for authentication. The username and password are for the switch’s
router to use when connecting to the ISP. When the Internet session starts, the ISP authenticates the username.
3. Set the Idle Time to an appropriate number. This number is the amount of time the PPPoE connection will be idle before
it disconnects. The 10000 second (default idle time is appropriate for most situations).
4. Check Keep Alive to instruct the switch to continue occasional communications over the WAN even when client
communications to the WAN are idle. Some ISPs terminate inactive connections, while others do not. In either case,
enabling Keep-Alive mode keeps the switch’s WAN connection alive, even when there is no traffic. If the ISP drops the
connection after so much idle time, the switch automatically reestablishes the connection to the ISP.
5. Select the appropriate WAN authentication method from the drop-down menu. Collect this information from the
network administrator. Select between None, PAP, CHAP, or PAP or CHAP.
6. Click the Apply button to save changes.
Step 7: Enable Wireless LANs (WLANs)
The WS 2000 Wireless Switch works either in a wired or wireless environment; however, the power of the switch is
associated with its support of wireless networks. In order to use the wireless features of the switch, the administrator needs
to enable up to four wireless LANs (WLANs).
To start the WLAN configuration process, select the Network Configuration --> Wireless item from the left menu. The
following Wireless summary screen appears.
CHAP
A type of authentication in which the person logging in uses secret information and some special mathematical operations to
come up with a number value. The server the person is logging into knows the same secret value and performs the same
mathematical operations. If the results match, the person is authorized to access the server. One of the numbers in the
mathematical operation is changed after every log-in, to protect against an intruder secretly copying a valid authentication
session and replaying it later to log in.
PAP
An identity verification method used to send a username and password over a network to a computer that compares the username
and password to a table listing authorized users. This method of authentication is less secure, because the username and
password travel as clear text that a hacker could read.
