This section contains FAQs for the conversion tool.
Q. Which VxWorks access point versions does the conversion tool support?
A. Table 1 lists the supported VxWorks access points and operating system versions:
Q. What are other conversion tool requirements for converting VxWorks access points?
A. Conversion tool requirements are given here:
1. A PC running the Windows 2000 or XP operating system and is not supported if Terminal Services is installed.
2. Minimum PC hardware:
–Processor: Pentium III or equivalent
–Speed: 850 MHz
–RAM: 128 MB
–Hard disk free space: 250 MB (4 MB for each helper image upgrade task)
3. The person installing and running the conversion tool must be logged in and must be the administrator of the PC.
4. All the access points (source and target) must have a user enabled with full access privileges (Write, SNMP, Ident, Firmware, and Admin).
–Use the User Information page to configure user privileges (Setup > Security > User Information)
5. SNMP must be enabled on the source and target access points (Setup > SNMP > Simple Network Management Protocol (SNMP): Enabled).
6. 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
7. Your VxWorks access points must have the following minimum contiguous free space to be successful:
–4.0 MB for 1200 series access points
–4.2 MB for 350 series access points
Note You can verify the amount of contiguous free memory in your access point by connecting to your access point using the console port or a Telnet session and entering the VxWorks command :vxdiag_memshow. The contiguous free memory is listed under the max block column.
Note For additional information on how to increase your contiguous free memory, refer to the Cisco Aironet Conversion Tool for Cisco IOS Software, 2.1 Administrator Guide for Windows.
8. The conversion tool should be used over Ethernet LANs and not over slower networks.
Caution You must ensure that the same Ethernet and duplex settings are configured on all VxWorks access points and network switches before beginning the conversion process. Different settings can result in inoperable access points that constantly power off and on.
9. If a VLAN is configured, a Native VLAN must also be configured in the access point.
10. If an Infrastructure SSID is configured, it must be mapped to the Native VLAN.
11. If BOOTP is configured, you must change to DHCP before running the conversion tool.
12. Use an IP address rather than a hostname for your authentication, accounting, and NTP servers.
13. You must ensure that your access points do not contain an 802.11g radio because the conversion tool supports only 802.11a and 802.11b radios.
14. You must use the correct helper image file identified in Table 1 for your access point.
Q. How many access point conversion processes can be supported at the same time?
A. The conversion tool supports a maximum of 20 conversion processes, but Cisco recommends using only 14 processes.
Q. Does the conversion tool support conversion of repeater access points?
A. Yes, the conversion tool supports repeater access points, but repeater and root access points (parent of the repeater access point) should not be converted at the same time.
Q. What is the minimum time for an access point conversion?
A. Under ideal conditions, the conversion process takes approximately 15 to 20 minutes for 1200 series access points and 20 to 25 minutes for 350 series access points. Actual conversion times might vary depending on your communication network, the number of access points being converted simultaneously, and other factors.
Q. What are the steps in the conversion process?
A. The conversion process performs these steps:
a. Learning Configuration process:
–Obtains the VxWorks configuration from your source access point using SNMP query commands.
–Converts the VxWorks configuration to a Cisco IOS configuration.
b. Uploading Image process:
–Encapsulates the Cisco IOS configuration with the upgrade image
–Sets up some of the MIB objects to clear more access point memory
–Uploads the special image to your target access point
c. Checking Device Status process:
–After the special image is uploaded, reboots the target access point
–While rebooting, installs the Cisco IOS software
–When the target access point is powered up, the conversion tool saves the running configuration to the start-up configuration.
Q. Why does the conversion process take so much time?
A. The conversion process is different from a normal firmware upgrade. It takes extra time because the upgrade image is larger and extra steps are required in the conversion process.
Q. Why did I receive the following error message during installation? Error: Setup has detected that unInstallShield is in use. Please close unInstallShield and restart setup. Error 432.
A. This error occurs when InstallShield tries to delete UNINST.EXE from the WINNT directory (so that it can install the latest version of the file) and you don't have administative privileges on the PC or the file has already been deleted. You must ensure the following:
–You have administrative privileges on the PC before installing the conversion tool.
–Only one instance of the InstallShield is running by only double-clicking the installation file Aironet-AP-Cisco-IOS-Conversion-Tool-v2.1.exe.
Q. Why did I receive the following error message during installation? Error: Uninstaller setup failed to initialize. You may not be able to uninstall this product.
A. This error occurs when you do not have administrative privileges on the PC and the conversion tool installation software attempts to save uninstall information in your Windows directory. You must ensure that you have administrative privileges on the PC before installing the conversion tool.
