Cisco Cisco Aironet 1310 Access Point Bridge

Depending on your specific requirements, you can take the following action:

If you need to transmit the multicast data with the greatest reliability and if there is no need for great 
multicast bandwidth, then configure a single basic rate, one that is low enough to reach the edges of 
the wireless cells.

If you need to transmit the multicast data at a certain data rate in order to achieve a certain 
throughput, then configure that rate as the highest basic rate. You can also set a lower basic rate for 
coverage of non-multicast clients.

When you convert an 1142 access point from LWAPP mode to autonomous mode, you might need to 
reboot the unit twice to complete the conversion.

A portion of the output of the show controller dot11radio CLI command displays the active power 
levels by rate as shown in the example below:

1.0 to 11.0  , 20  dBm, changed due to regulatory maximum

6.0 to m15.  , 17  dBm, changed due to regulatory maximum

m0.-4 to m15.-4, 14  dBm, changed due to regulatory maximum

The -4 in the third line indicates 40-MHz.

A 1250 series access point that is running a Cisco IOS Release prior to (insert Krypton release number 
here) does not generate a crash log when it crashes. The crash log is disabled so that a crash does not 
corrupt the flash file system. 

New 1250 series access points shipped from the factory contain a new bootloader image that fixes the 
flash file system after it is corrupted during a crash (without losing files). This new bootloader 
automatically sets a new CRASH_LOG environment variable to “yes,” which enables a crash log to be 
generated following a crash. Therefore, no user configuration is needed to enable a crash log on new 
1250 series access points shipped from the factory.

To enable 1250 series access points in the field to generate a crash log following a crash, install Cisco 
IOS Release 12.4(10b)JA or later and enter this case-sensitive bootloader CLI command on the access 
point: set CRASH_LOG yes. When you set this CLI, the access point does not immediately generate a 
crash log. The log is generated after a crash occurs. After the crash log is generated, enter this command 
to disable the CRASH_LOG environment variable to minimize the risk of corrupting the flash file 
system: set CRASH_LOG no.

If your network uses 16 BSSIDs with 1- and 2-Mbps data rates, 1140 and 1250 series access points might 
experience very low throughput due to high management traffic.
