Multiple SSIDs: SSID Broadcast

Multiple SSIDs lets you mix and match the broadcasting of SSIDs. Each SSID can support
its own set of broadcast and multicast encryption keys. The encryption keys are optional.
This ensures that broadcast and multicast packets are properly received by clients on the
same SSID.
Only one SSID in an SSID Table can have broadcast "active".
Note: If broadcast is enabled to transmit an SSID in its beacon, then closed system must be
set to disabled or "accept-any".

Multiple SSIDs: Closed System

You can set an SSID to be a closed system. This means a client must have the same SSID as
the Access Point in order to communicate. For example, if a client has an SSID of "Any" and
is trying to communicate with an Access Point that has an SSID of "Marketing", it will not
be able to communicate with the Access Point in a closed system.
If closed-system is enabled (not-accept-any), the setting of the broadcast command has no
effect. With closed-system enabled, this prevents the SSID from being broadcast even if
broadcast was enabled.

Multiple SSIDs: Security

You can assign each SSID to its own security settings. These security settings are described
in detail in
• None
• Wired Equivalent Privacy (WEP) - uses static keys on every station.
• 802.1x - requires a RADIUS server.
• WiFi Protected Access (WPA) - requires a RADIUS server. This is more secure than
WEP because of the following:
— Improved data encryption through the temporal key integrity protocol (TKIP).
TKIP scrambles the keys using a hashing algorithm and, by adding an integrity-
checking feature, ensures that the keys haven not been tampered with.
— User authentication through the extensible authentication protocol (EAP). WEP
regulates access to a wireless network based on a computer's hardware-specific
MAC address, which is relatively simple to be sniffed out and stolen. EAP is built
on a more secure public-key encryption system to ensure that only authorized
network users can access the network.
