In June 2003, Cisco Systems released an upgrade image that allows Cisco Aironet 1200 Series Access Point (AP) products to run Cisco IOS® Software. Cisco later introduced the option to run Cisco IOS Software for Aironet 350 Series APs. In addition to the and the, this document provides background for the upgrade procedure and offers recovery steps in the event that the upgrade does not occur as expected. Although this document focuses on the 1200 Series APs, you can find information for the 350 Series APs in the Conversion Tool documentation.
Cisco IOS Software Release 12.4(3G)JA. And Cisco Aironet 1240AG and 1130AG Series Access Points. JA is available as a free software upgrade. I have a quick question for you guys (or girs for that matter;) I have a Cisco Aironet 1100-series access point with current firmware 12.3(8)JEA, but want to upgrade it if possible.
Caution: The upgrade of VxWorks firmware to Cisco IOS Software is permanent. Because the VxWorks bootloader overwrites, no downgrade procedure exists. Product warranties do not cover unplanned upgrades.
Cisco recommends that you have: • Familiarity with the general operation of Aironet 1200 Series AP products • Prior experience with the upgrade of a VxWorks-based AP to a later maintenance release • General knowledge of file transfers and transfer protocols The information in this document is based on these software and hardware versions: • Aironet 1200 Series AP • These VxWorks Operating System versions: • 11.54T • 11.56 • 12.01T1 • 12.02T1 • 12.03T Versions that are later than 12.03T do not work with the upgrade image. • The upgrade image itself: AP1200-Cisco-IOS-Upgrade-Image-v3.img You can download this from ( customers only).
Note: The version number of the upgrade image may change over time. However, the file name always has the format of AP1200-Cisco-IOS-Upgrade-Image-v x.img. Note: If you upgrade a VxWorks-based AP with the file c1200-k9w7-tar, 122-15.JA.tar, or any other Cisco IOS Software maintenance release, the upgrade fails with the error Bad File Format. Use the AP1200-Cisco-IOS-Upgrade-Image-v3.img file instead. Note: In order to upgrade from a VxWorks-based AP to Cisco IOS Software, your AP must run one of these VxWorks firmware versions: • 12.03T • 12.02T1 • 12.01T1 • 12.00T • 11.23T • 11.21 • 11.56 • 11.54T If you have VxWorks with a firmware version that is earlier than these versions, you must upgrade your VxWorks to one of these versions. For instructions on how to upgrade the VxWorks firmware, refer to.
If you have VxWorks with the firmware version 12.04 or later, you must first downgrade VxWorks to one of the earlier versions. You cannot upgrade to Cisco IOS Software from VxWorks unless you perform this downgrade. As an example, this document includes instructions to downgrade VxWorks firmware to 12.03T. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration.
If your network is live, make sure that you understand the potential impact of any command. In order to run the upgrade process, the AP must have at least 4 MB of DRAM available. Issue the:vxdiag_memshow VxWorks command, at the prompt of a console or of a Telnet session, in order to display the amount of free DRAM.
(Auto Apply On):BOttom,:Down,:Back, ^R, =,, or [Link Text]::vxdiag_memshow status bytes blocks avg block max block ------ --------- -------- ---------- ---------- current free 3263544 370 88 alloc 100 1832 - cumulative alloc 1190 733 - This example shows that the free memory is 3,263,544 bytes, or approximately 3.2 MB. The upgrade procedure, therefore, does not run successfully. In order to increase free DRAM, you must terminate noncritical processes or temporarily disable other resources (like a second radio).
