Introduction

The conversion tool is a special utility that is used by administrators to do the following:

Create a Cisco IOS configuration using the configuration of an existing non-IOS 350 or 1200 series access point. Store a Cisco IOS configuration file on your PC for later use.

Upgrade non-IOS 1200 series access points to Cisco IOS operation by combining the Cisco IOS configuration file with a 1200 series helper image. Converts the access point to Cisco IOS Release 12.2(11)JA1.

Upgrade non-IOS 350 series access points to Cisco IOS operation by combining the Cisco IOS configuration file with a 350 series helper image. Converts the access point to Cisco IOS Release 12.2(13)JA1.

To find your access point software release (Cisco IOS or non-IOS) refer to the "Access Point Software Version" section.


Caution The conversion tool cannot reverse the Cisco IOS upgrade process. Be sure that you want to upgrade your access point to Cisco IOS operation before using the conversion tool.

System Requirements

The conversion tool has the following system requirements:


Note The conversion tool does not support Non-IOS 350 and 1200 series access points running operating system version 12.04. Access points running operating system version 12.04 must be downgraded to a supported operating system version before using the conversion tool.


Non-IOS 350 series access points running operating system version 12.03T, 12.02T1, 12.01T1, 11.23T, and 11.21.

Non-IOS 1200 series access points running operating system version 12.03T, 12.02T1, 12.01T1, 12.00T, 11.56, or 11.54T.

The conversion tool operates only on a PC with the Windows 2000 or XP operating system.

The conversion tool requires the following 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)

When using the minimum PC hardware, the conversion tool supports up to 14 parallel helper image upgrades. You can enter up to 20 tasks, but only 14 of the tasks (maximum) can be helper image upgrades, and the remaining tasks can be used to store the access point's Cisco IOS configurations on your hard disk. Prior to starting multiple helper image upgrade tasks, you should verify that your PC has sufficient disk space.


Note When you upgrade your access points, you can recover disk space by deleting the Cisco IOS configurations (with helper images) that were saved in the ConversionToolDirectory/images folder.



Note The limit of 14 parallel helper image upgrades depends solely on the ability of the system and the network to handle multiple TFTP jobs. Faster systems, disks, and networks may be able to handle more parallel upgrade tasks, though too many tasks impact the speed of the individual tasks.


The person installing and running the conversion tool must be logged in and must be the administrator of the PC.

All your access points (source and target) must have an administrator enabled with admin, SNMP, write, and firmware privileges for the access point.


Note For additional information on SNMP, refer to the Cisco IOS Software Configuration Guide for Access Points.


SNMP must be enabled on the source and target access points.

The conversion tool uses SNMP commands to obtain configuration data from the source access point, but certain 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 non-IOS access points was acquired using the Download All System Configuration option on the access point's System Configuration window. You should use the configuration (.ini) file acquired using the Download Non-Default System Configuration option.

The upgrade process requires a minimum of 4 MB of free space in your non-IOS access points to be successful.


Note To ensure that your access points have sufficient free space you must set the maximum memory reserved for the Detail Event Trace Buffer to zero. The maximum memory setting is located on the Event Handling screen in the Event Log section of your non-IOS access point.


Important Notes

This section describes important information about the upgrade of 350 series access points to IOS software. For more information on Cisco IOS releases for access points, refer to the release notes for specific releases.

Some Fields Not Updated During Upgrade to IOS Software

During the access point's power-up sequence after an upgrade to IOS software, some fields reported in the console messages are blank or are populated with zeros. However, blank or zero fields are normal after a successful upgrade, because 350 and 1200 series access points do not support that information. This example shows fields that might appear blank or populated with zeros:


32K bytes of flash-simulated non-volatile configuration memory.

Copyright (c) 1986-2003 by Cisco Systems, Inc. 

On access points running Cisco IOS software, you can also find the software version on the System Software Version page in the access point's browser interface.

If your access point does not run Cisco IOS software, the software version appears at the top left of most pages in the browser interface.

New Conversion Tool Feature

The conversion tool supports the following new feature:

Device Type—the conversion tool supports two non-IOS access points.

350 series access points

1200 series access points

Limitations and Restrictions

Conversion Tool Operating Cautions

You should carefully review the following list of cautions to avoid potential problems when using the conversion tool.

The conversion tool automatically installs a TFTP server during the installation process and may not detect the presence of an existing TFTP server installed on your PC. You should deactivate the existing TFTP server prior to installing and using the conversion tool.

The conversion tool's TFTP server is activated only when the conversion tool is activated. When you deactivate the conversion tool, the TFTP server is also deactivated.


Note You cannot use the conversion tool's TFTP server for other file transfer purposes.


The Admin Name setting is not visible in the conversion tool and is displayed as a set of asterisks.

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 non-IOS 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 upgrade process may not be successful when the configuration of your non-IOS access points was acquired using the Download All System Configuration option on the access point's System Configuration window. You should use the configuration (.ini) file acquired using the Download Non-Default System Configuration option.

The upgrade process requires a minimum of 4 MB of free space in your non-IOS access points to be successful. To ensure that your access points have sufficient free space you must set the maximum memory reserved for the Detail Event Trace Buffer to zero. The maximum memory setting is located on the Event Handling screen in the Event Log section of your non-IOS access point.

Limitations in the Cisco IOS Configuration

Because of differences between the configuration settings in your non-IOS access point and the Cisco IOS configuration settings, the conversion tool has the following limitations:

The configuration of a Policy Group on an SSID without a VLAN are not migrated.

A maximum of 100 Ethertype filters can be created.

Ethertype filters do not have associated names; instead, they have associated numbers ranging from 200 to 299.

Separate filters are created for the Ethertype, IP port, and IP protocol filters that have been set to non-default priority. This may create multiple filters with the same numeric identifier, but the conversion tool inserts a numeric index to differentiate the filters.

Port filters, Protocol filters, Ethertype filters, and Policy Groups are created in the following format:

Port filter—IP access list extended <Port_Filter_Name> _ <Numeric_Value>

Protocol filter—IP access list extended <Protocol_Filter_Name> _ <Numeric_Value>

Ether filter—access-list <Numeric_Value> <permit or deny> <Protocol-Type>

Policy-Groups—policy-map_policy_ <Name>_<Policy_ID>

For BOOTP protocol settings, DHCP settings are configured.

Only DHCP configuration settings with a Client Identifier type of Ethernet are migrated. All other Client Identifier types are discarded.

If DHCP is configured, the fall-back IP addresses are not configured.

Port assignments are not migrated.

The Hot Standby configuration settings are migrated only when the radio MAC addresses are entered on the conversion tool's Device Configuration window.

If the station role is configured as Client/NonRoot, the station role is migrated as Root.

For the Console/Telnet settings, only the Enable and Disable settings are migrated.

For the HTTP configuration settings, only the HTTP port and the Enable or Disable settings are migrated.

VLANs are migrated only when they are associated with an SSID.

Only MAC based filter settings with SSIDs associated to a VLAN and with MAC authentication enabled are migrated. The log file contains a list of the MAC filters that are not migrated.

The Alert settings in filters are not migrated.

AAA server timeout settings range from 1 to 1000. If the configured setting is greater than 1000, the migrated setting is 1000. If the configured setting is less than 1, the migrated setting is 1.

AAA server retransmission settings range from 1 to 100. If the configured setting is greater than 100, the migrated setting is 100. If the configured setting is less than 1, the migrated setting is 1.

Separate EAP and Non-EAP accounting server settings are not migrated. After an accounting server is enabled, all the users are configured to use that server.

System names containing a space are migrated with an underscore (_) replacing the space. For example; a name of AP 1200 is migrated as AP_1200.

LEAP usernames with a space are not migrated.

The following Ethernet parameters are not migrated:

Optimize Network for maximum multicast packets per second, loss of backbone connectivity timeout value, and maximum multicast packets per second.

The following Boot Server configuration parameters are not migrated:

DHCP Multiple-Offer Timeout

DHCP Requested Lease Duration

DHCP Minimum Lease Duration

DHCP Client Identifier Value

The FTP and TFTP configuration parameters are not migrated.

The following AAA Server configuration parameters are not migrated:

Port configuration settings for TACACS server

802.1X Protocol Version (for EAP authentication)

Update Delay per Server for the Accounting Server

The following configuration settings are not migrated:

Rogue AP Alert Timeout

Unknown Class Timeout

Multicast Addresses Timeout

Infrastructure Hosts, Client Stations, and Repeater Timeout

When both port and protocol filters are applied on an interface

Default multicast address filtering for an interface

Maximum RTS Retries settings range from 1 to 128. If the configured setting is greater than 128, the migrated setting is 128.

Maximum Data Retries settings range from 1 to 128. If the configured setting is greater than 128, the migrated setting is 128.

Data Beacon Rate (DTIM) settings range from 1 to 100. If the configured setting is greater than 100, the migrated setting is 100.

Beacon Period settings range from 20 to 4000. If the configured setting is greater than 4000, the migrated setting is 4000 and if the configured setting is less than 20, the migrated setting is 20.

WEP Key Rotation Interval settings range from 1 to 10. If the configured setting is greater than 10, the migrated setting is 10.

If the configured settings for the LEAP or EAP transmit key is not set to Key 1, the following error is produced by Cisco IOS software in the migrated configuration:

Error: LEAP/EAP authentication does not support the key index#.

If the configured setting for DSCP is not a specific value (0, 1, 2, 3, 4, 5, 6, 7, 11, 12, 12, 21, 22, 23, 31, 32, 33, 41, 42, or 43), the following error is produced by Cisco IOS software in the migrated configuration when viewing the settings using the HTTP interface.

Policy_policy_fallback_policy was created using CLI. It must be deleted via CLI to ensure proper operation of the web interface.


Note Even though this error message is displayed, the migrated configuration and the associated functionality are correct.


Caveats

Open Caveats

There are no open caveats.

Closed Caveats

CSCeb47743—Problem with passwords containing an exclamation mark (!). When running the conversion tool if the password contains an exclamation mark, the exclamation mark is treated as a carriage return and the password is terminated at that point.
