FTD 2120 rommon issue


Working on 2 ftds today, one those FTD2120 was continuously booting in rommon. At the beginning I didn’t realized that was confreg issue. Thus, I proceeded and fully reimaged the device.

Once I reimaged on the reload FTD stacked again on rommon.

Then I realized that was something wrong with confreg on rommon

Running the help command I saw the confreg command

Running the confreg I saw the below

"Configuration Register: 0x00000000"

 

Then I run the command confreg 0x1 from rommon


rommon 9 >  confreg 0x1

You must reset or power cycle for new config to take effect

 rommon 10 > reboot

Restarting the system...


After that everything was ok 😊

Upgrade WLC / Supplementary image

  Today I had to upgrade an AIROS cisco 2504 WLC. After checking if the APs are supported by the new recommended version I noticed that I had to install the supplementary image also. The reason was that 1602i APs wasn’t supported by the main image in 8.5.171.0 version. Due to image size cisco created separate file for some AP images called Supplementary AP Bundle image. Procedure:   Step 1:   Check the current WLC image (Cisco Controller) >show boot Primary Boot Image............................... 8.3.150.0 (default) (active) Backup Boot Image................................ 8.0.152.0 Step 2: Upload the new image ( AIR-CT2500-K9-8-5-171-0.aes ) I did the below procedure via HTTPS. Verify (Cisco Controller) >show boot Primary Boot Image............................... 8.5.171.0 (default) Backup Boot Image................................ 8.3.150.0 (active) Step 3: Check Supported APs of the new version (Cisco Controller) >show ap bundle primary Primary Version
