Viewing and configuring switch WLANs
4
A WLAN screen displays with the WLAN’s existing configuration. Refer to the Authentication
and Encryption columns to assess the WLAN’s existing security configuration.
4. Select the Kerberos button from within the Authentication field.
NOTE
Kerberos requires at least one encryption scheme be enabled (WEP 128 or other). If neither WEP
128 or KeyGuard is enabled, WEP 128 will automatically be enabled for use with Kerberos.
5. Click the Config button to the right of the Kerberos checkbox. The Kerberos screen displays.
6. Specify a case-sensitive Realm Name.
The realm name is the name domain/realm name of the KDC Server. A realm name functions
similarly to a DNS domain name. In theory, the realm name is arbitrary. However, in practice a
Kerberos realm is named by uppercasing the DNS domain name associated with hosts in the
realm.
7. Provide the password required to effectively update Kerberos authentication credentials.
8. Enter a Server IP Addr (IP address) for the Primary and (if necessary) Backup KDC.
Specify a numerical (non-DNS) IP address for the Primary Key Distribution Center (KDC). The
KDC implements an Authentication Service and a Ticket Granting Service, whereby an
authorized user is granted a ticket encrypted with the user's password. The KDC has a copy of
every user password provided. Optionally, specify a numerical (non-DNS) IP address for a
backup KDC. Backup KDCs are often referred to as slave servers.
9. Specify the Ports on which the Primary and Backup KDCs reside.
The default port number for Kerberos Key Distribution Centers is port 88.
10. Refer to the Status field for the current state of requests made from applet. This field displays
error messages if something goes wrong in the transaction between the applet and the switch.
11. Click OK to use the changes to the running configuration and close the dialog.
12. Click Cancel to close the dialog without committing updates to the running configuration.
Configuring hotspots
A hotspot is essentially a Web page granting user access to the Internet (in this case within a
switch managed WLAN). With the influx of Wi-Fi enabled mobile devices (laptops, PDAs etc.),
hotspots are common and can be found at many airports, hotels and college campuses.
