Cisco Cisco Aironet 1040 Series Access Point Notas de publicación

You must use a Wireless LAN Services Module (WLSM) as your WDS device in order to properly 
configure Layer 3 mobility. If you enable Layer 3 mobility for an SSID and your WDS device does not 
support Layer 3 mobility, client devices cannot associate using that SSID.

The beacons on the Cisco Aironet 1250 and 1140 Access Points can only have output at intervals that 
are multiples of 17 milliseconds. When these access points are configured for a 100 millisecond beacon 
interval, they transmit beacons every 102 milliseconds. Similarly, when the beacon interval is configured 
for 20 milliseconds, these access points transmit beacons every 17 milliseconds. 

When the following command is configured under the SSID settings (for LEAP authentication):

authentication client username <WORD> password [0 | 7] <LINE>

If the first access-challenge returned by the Radius server after the access-request from the access point 
is not for the LEAP method but for EAP-MD5, the acces point violates RFC 3748.

Instead of sending an EAP NAK requesting LEAP authentication, the access point sends the user's 
credentials with EAP-MD5 and drops the derived keys, since it cannot read the EAP-MD5 from the 
access-accept.

This violates RFC 3748.

The workaround for this is to use the commands 

dot1x credentials 

and 

dot1x eap profile

 for LEAP 

authentication.

For configuration procedures, see Cisco IOS Software Configuration Guide for Cisco Aironet Access 
Points, x.x.

12.4(25d)JA. For your convenience in locating caveats in Cisco’s Bug Toolkit, the caveat titles listed in 
this section are drawn directly from the Bug Toolkit database. These caveat titles are not intended to be 
read as complete sentences because the title field length is limited. In the caveat titles, some truncation 
of wording or punctuation might be necessary to provide the most complete and concise description. The 
only modifications made to these titles are as follows:

Commands are in boldface type.

Product names and acronyms may be standardized.

Spelling errors and typos may be corrected.
