how to know update/upgrade

Sep 7, 2010 12:33 PM

Hello people,



Im practicing in a AP some commands, and i would like to know what considerations I need to take to make an update/upgrade, what is the proccess?? how can i know if my AP needs or not an update/upgrade, let`s say that this is the AP that i would like to check if is viable update/upgrade:


Cisco IOS Software, C1240 Software (C1240-K9W7-M), Version 12.3(11)JA, RELEASE SOFTWARE (fc2)

System image file is "flash:/c1240-k9w7-mx.123-11.JA/c1240-k9w7-mx.123-11.JA"


32K bytes of flash-simulated non-volatile configuration memory.
Base ethernet MAC Address: 00:1B:D4:6C:07:3A
Part Number                          : 73-9925-06
PCA Assembly Number                  : 800-26579-05
PCA Revision Number                  : A0
PCB Serial Number                    : FOC111603T6
Top Assembly Part Number             : 800-29151-02
Top Assembly Serial Number           : FTX1118B1YN
Top Revision Number                  : A0
Product/Model Number                 : AIR-LAP1242AG-A-K9


By the way, somebody knows if this AP supports WPA2, it is related to the term WLAN G6??, I googled this term (G6) and I could not find so much...

    Re: how to know update/upgrade

    To know if you need an update or upgrade really depends on the features you have versus what you need. No sense in upgrading to a new image just because. That AP should support WPA2. I have an AIR-AP1231G-A-K9 and it supports WPA2. Running version

    Another reason to upgrade code is when there are known bugs in the current version.

    Do some research and see if you need features.  As Scott would say; "Just because you can, doesn't mean you should."  Sometimes, upgrading causes more problems that if you were to just leave it alone.  Look for caveats in the release notes and make the decision that's best for the company.

    Re: how to know update/upgrade

    Erick's statement says it all!  Back when I was doing autonomous APs, I upgraded for 3 reasons:


    1) new features

    2) bug fixes

    3) If you call TAC, they may have you upgrade to the latest code.

    4) preperation for Lightweight AP conversion.


    I usually don't do it just for fun.

    Another thing about the last statement that a wrote down, you told me that WPA2 is supported by AP1242, however I couln`t find where to configure it

    (need I to update??).


    Check out on the CLI. You should have a line like: authentication key-management wpa

    Depending on the version, you can specify or not the WPA version there.

    According to the command reference, you get the choice beginning from version 12.3(8)JEB.

    Re: how to know update/upgrade

    here is how I have it configured on my home AP which is a 1232.


    config t

    dot11 ssid NAME
       authentication open
       authentication key-management wpa
       wpa-psk ascii 7 xxxxxxx

    interface Dot11Radio0
    no ip address
    no ip route-cache
    encryption mode ciphers aes-ccm tkip
    ssid NAME
    speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0
    channel 2462
    station-role root
    bridge-group 1
    bridge-group 1 subscriber-loop-control
    bridge-group 1 block-unknown-source
    no bridge-group 1 source-learning
    no bridge-group 1 unicast-flooding
    bridge-group 1 spanning-disabled



    With this configuration I have it configured as WPA2 encryption and I turned off SSID broadcasting. Show if you use a wireless network radar, it just shows as hidden network. Here is the version of software I am using to do this.
