Chapter 3 Configuring the Radio and Basic Settings
Radio Configuration
SSID for use by Infrastructure Stations (such as Repeaters)
Identifies the SSID to be used by repeaters and workgroup bridges to associate to
the access point. It is also the SSID used by a non-root bridge to associate to a root
bridge. This SSID should be mapped to the native VLAN ID in order to facilitate
communications between infrastructure devices and a non-root access point or
bridge.
Disallow Infrastructure Stations on any other SSID
Prevents repeaters or workgroup bridges from associating to SSIDs other than the
infrastructure SSID. The default setting is No, so to invoke this condition, you
must change the setting to Yes .
Use Aironet Extensions
Select yes or no to use Cisco Aironet 802.11 extensions. This setting must be set
to yes (the default setting) to enable these features:
• Load balancing—The access point uses Aironet extensions to direct client
devices to an access point that provides the best connection to the network
based on factors such as number of users, bit error rates, and signal strength.
• Message Integrity Check (MIC)—MIC is an additional WEP security feature
that prevents attacks on encrypted packets called bit-flip attacks. The MIC,
implemented on both the access point and all associated client devices, adds
a few bytes to each packet to make the packets tamper-proof.
• Temporal Key Integrity Protocol (TKIP)—TKIP, also known as WEP key
hashing, is an additional WEP security feature that defends against an attack
on WEP in which the intruder uses an unencrypted segment called the
initialization vector (IV) in encrypted packets to calculate the WEP key.
• The extensions also improve the access point’s ability to understand the
capabilities of Cisco Aironet client devices associated with the access point.
Classify Workgroup Bridges as Network Infrastructure
Select no to allow more than 20 Cisco Aironet Workgroup Bridges to associate to
the access point. The default setting, yes, limits the number of workgroup bridges
that can associate to the access point to 20 or less.
