Enter ROMMON to flash new AP image

Some time ago I had to convert a 2600 Series AP from Controller-based to a Standalone Acess Point. I’m doing this in the following way: Restart the Access Point, press ESC in console to enter ROMMON.


    ap: set IP_ADDR 10.0.0.1
    ap: set NETMASK 255.255.255.0

    ap: tftp_init
    ap: ether_init

Verify ROMMON variables

After I set up the network and initialized it, I am always checking the ROMMON variables.


    ap: set
    DEFAULT_ROUTER=10.0.0.1
    ENABLE_BREAK=yes
    IP_ADDR=10.0.0.1
    MANUAL_BOOT=no
    NETMASK=255.255.255.0
    ROM_PERSISTENT_UTC=1367418162
    TERMLINES=0

Copy image from TFTP server

Then I’m doing a simple TFTP copy. As TFTP server for windows I am using Tftpd32 - Tftpd64, which is released under the EUPL V1.1. It might be possible to make some space on the flash memory before copying the image. Also it’s worth to verify the flash memory if the TFTP copy was successful.


    tar -xtract tftp://10.0.0.2/ap3g2-k9w7-tar.153-3.JE.tar flash:



    ap: dir flash:
    Directory of flash:/

    2    -rwx  1048      -date-               private-multiple-fs
    3    -rwx  279       -date-               info
    5    drwx  2496      -date-               ap3g2-k9w7-mx.153-3.JE
    248  -rwx  279       -date-               info.ver
    249  -rwx  286       -date-               env_vars
    13   drwx  192       -date-               ap3g2-rcvk9w8-mx

Set boot variable to new image

Before I reboot the Access Point with the new image I set the BOOT variable to the new Image and verify the ROMMON variables again.


    ap: set BOOT flash:/ap3g2-k9w7-mx.153-3.JE/ap3g2-k9w7-mx.153-3.JE

    ap: set
    BOOT=flash:ap3g2-k9w7-mx.153-3.JE/ap3g2-k9w7-mx.153-3.JE
    DEFAULT_ROUTER=10.0.0.1
    ENABLE_BREAK=yes
    IP_ADDR=10.0.0.1
    MANUAL_BOOT=no
    NETMASK=255.255.255.0
    ROM_PERSISTENT_UTC=1367418162
    TERMLINES=0

    ap: boot
