Cisco Cisco Aironet 1240 AG Access Point 릴리즈 노트

Do not attempt to load software images into the bridge from both a Telnet session and a console session 
simultaneously. The bridge cannot detect that two images are being loaded at the same time. For best 
results, use the archive download command in the CLI.

The bridge sometimes cannot detect invalid software images when you load software using the copy 
command. For best results, use the archive download command in the CLI to load new software.

When the bridge is transmitting and receiving heavy traffic, you sometimes cannot start a Telnet session 
and some existing Telnet sessions halt. However, this behavior is expected because the bridge gives top 
priority to data traffic and a lower priority to Telnet traffic.

This section describes important information about access points and bridges.

When a 7921 or 7925 wireless associates to an access point in a WDS with CCKM, it cannot fast roam 
because call admission control is not enabled. To work around this issue you must enable admission 
control by issuing the admit-traffic command in the access point SSID configuration as shown in the 
following example:

dot11 ssid voice

vlan 21

authentication open eap eap_methods

authentication network-eap eap_methods

authentication key-managemenet wpa cckm

admit-trafficH

When an access point detects a radar on a DFS channel, the access point creates a file in its flash memory. 
The file is based on the 802.11a radio serial number and contains the channel numbers on which the the 
radar is detected. This is an exepected behavior and you should not remove this file. See the caveat 
CSCsv36602 in the 

Access points running recent Cisco IOS versions are transmitting multicast and management frames at 
the highest configured basic rate, and is a situation that could causes reliability problems.
