Примечания к выпуску для Cisco Cisco Aironet 1200 Access Point

If you bypass the entry of security information and if User Manager is enabled in your source access 
point, you might not be able to log in on the upgraded access point. All access to the access point 
might be blocked (Telnet, browser, and the console port). If this occurs, you must reset the access 
point to defaults using the mode button (refer to the “Troubleshooting” section of the Cisco Aironet 
1200 Series Access Point Hardware Installation Guide or the Cisco Aironet 350 Series Access Point 
Hardware Installation Guide).

If you bypass the entry of security information and if User Manager is disabled in your VxWorks 
access point, you can only log in on the upgraded access point using the console port.

Upgrade tasks should not be performed on both root and repeater access points at the same time 
because this causes the repeater upgrade task to fail.

The conversion tool uses SNMP commands to obtain configuration data from the source access 
point, but some security information cannot be accessed using SNMP. Before you use the conversion 
tool, you should obtain the following source access point security information:

The WEP keys used for the radio interfaces and VLANs

The LEAP passwords for repeater access points

The passwords used with the User Manager Configuration

AAA Server Configuration Secret Keys

The upgrade process may not be successful if the configuration of your VxWorks access points was 
acquired by choosing the Download All System Configuration option on the access point’s System 
Configuration window. You should use the configuration (.ini) file acquired choosing the Download 
Non-Default System Configuration option.

The upgrade process requires the following minimum contiguous free space in your VxWorks access 
points to be successful:

4.0 MB for 1200 series access points

4.2 MB for 350 series access points

You can verify the amount of free memory in your access point by connecting to your access 
point using the console port or a Telnet session and entering the command :vxdiag_memshow. 
The amount of contiguous free memory is listed in the max block column.

Complete these steps to increase the amount of free memory in your access point:

If your access point runs an .ini configuration file acquired by choosing the Download All 
System Configuration options from the Web interface, replace the configuration with an .ini 
file acquired by choosing the Download Non-Default System Configuration option.

On Cisco Aironet 1200 series access points, you can remove the 802.11a radio module to obtain 
additional free space.

If necessary, you can free additional memory in your access point by performing these steps on the 
Setup > Associations > Advanced page:

Disable the RFC 1493 802.1D Statistics in MIB (dot1dTpFdbTable) and the Aironet 
Extended Statistics in MIB (awcTpFdbTable) options.

Enable the Map Multicast Entries to Broadcast Entry option.
