Chapter 3 Configuring the Radio and Basic Settings
Radio Configuration
• 802.1H—This default setting provides optimum performance for Cisco
Aironet wireless products.
• RFC1042—Use this setting to ensure interoperability with non-Cisco Aironet
wireless equipment. RFC1042 does not provide the interoperability
advantages of 802.1H but is used by other manufacturers of wireless
equipment.
Quality of Service Setup Link
Clicking on the Quality of Service (QoS) Setup link accesses the the AP Radio
Quality of Service page. Use this page to configure the radio’s QoS setup and
priorities. Read the “Quality of Service Support” section on page 1-5 for a
description of QoS. See the “QoS Configuration” section on page 5-10 to set up
QoS.
VLAN Setup Link
Clicking the VLAN Setup link accesses the VLAN Setup page. Use this page to
configure, add, edit, and remove VLANs associated with your access point. Read
the “VLAN Support” section on page 1-6 for a description of VLANs. Go to the
“Creating and Configuring VLANs on the Access Point” section on page 4-11 to
set up VLANs.
Enhanced MIC verification for WEP
This setting enables Message Integrity Check (MIC), a security feature that
protects your WEP keys by preventing attacks on encrypted packets called bit-flip
attacks. During a bit-flip attack, an intruder intercepts an encrypted message,
alters it slightly, and retransmits it, and the receiver accepts the retransmitted
message as legitimate. 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. Select MMH from the drop-down menu and click Apply to enable
MIC.
Note MIC takes effect only when the Use Aironet Extensions setting on the AP Radio
Advanced page is set to yes and WEP is enabled and set to full encryption.
