Cisco Aironet 1200 Series

AP1200s with Incorrect Boot Loader Image


Updated April 30, 2003

March 14, 2003



Products Affected

Cisco Aironet Access Point (AP) 1210 and 1230

Problem Description

Cisco Aironet AP1210s and 1230s were built with a pre-release version of bootloader. The bootloader should be upgraded to released version for optimal performance.

One defect with the unreleased boot loader is that, if the AP has no Ethernet connection at boot time, the boot process will abort and the AP will stay at the boot loader prompt. Manual intervention is then required (type the boot command at the AP console) to force the AP to continue to boot. This is particularly an issue for APs configured as repeaters which normally have no Ethernet connection.

Background

Cisco Aironet AP 1210s and 1230s were shipped from the factory with an unsupported boot loader image and need to be upgraded to the released version of boot loader.

Problem Symptoms

The output of the show version command on an AP with the unsupported boot loader will contain the following text:

ROM: Bootstrap program is C1200 boot loader
BOOTLDR: C1200 Boot Loader (C1200-BOOT-M), Version 12.2 [BLD-argon 102]

Workaround/Solution

Follow this procedure to upgrade the boot loader:

  1. Place the bootloader image in the proper directory on a TFTP server.

  2. Connect to the AP console. Once connected, use the enable command to enter privileged mode.

  3. Upgrade the boot loader by downloading the new boot loader image from the TFTP server to the AP boot sector using the following command: copy tftp://ip address/path/c1200-boot-m.122-8.JA bs: where ip address is the address of the TFTP server and path is the path to the directory where the boot loader image is located.

  4. Once the boot loader upgrade is complete, type reload at the AP console prompt to reboot the AP and verify that it boots using the upgraded boot loader.
