    how to know update/upgrade

    MGGN

      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...

          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.

                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.

                  Excelent answers friends, my  question was because  I though that it works like a PCS, Let´s example

                   

                  guy1: hello guy2,
                  guy2: Hello guy1, what about your computer,what OS do u have??
                  guy1: I have WinXP..
                  guy2: WinXP??? HAHAHA, is so old, now the coolest is 7!! you
                  have to upgrade/update to 7 because is more secure, flexible
                  and nice.


                  And when I saw the version of my AP`s OS (12.3) I felt that
                  I would have to migrate to 12.4.

                   

                  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??).

                  I attach the image.

                    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.

                      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
                      54.0
                      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.
