Καλησπέρα,

Αν έχω καταλάβει καλά από το documentation, του βάζω το option 43 στο dhcp του router με μία ip και μετά με "service-module wlan-ap 0 bootimage unified" του λέω να κάνει upgrade; Αλλά αυτό κάνει upgrade στο Unified, το οποίο δεν είμαι σίγουρος τι είναι και αν το θέλω, παρόλο που το έχω διαβάσει αρκετές φορές δεν έχω καταλάβει την διαφορά του από το autonomous.

Πριν αρχίσω το configuration του wireless θα ήθελα να του κάνω upgrade :) Οποιοδήποτε hint είναι ευπρόσδεκτο. Στα release notes του wireless control module λέει ότι το κάνεις upload κάπου το οποίο πάλι δεν κατάλαβα πιο software είναι. Κανένα CISCO configuration τάδε. Με το CLI πως στο καλό γίνεται. Έχει περίεργη δομή το AP και δεν είναι μόνο ένα απλό image όπως ο router :)

Δεν ξερω πως θα κανεις upgrade, αυτο που μπορω να πω ειναι οτι autonomous ειναι οταν δεν χρειαζεται central control device (WLC) για να λειτουργησει. Unified (Lightweight) στην αντιθετη περιπτωση :)

Άρα για μόνο του στο σπίτι το autonomous είναι αυτό που χρειάζομαι.

Q. Is the Cisco 880 Series orderable with unified mode already enabled?
A. Customers that purchase directly from Cisco can configure this when placing the order with the Cisco Dynamic Configuration Tool. Cisco 880 Series routers sold through distribution will have autonomous mode enabled by default with the option for migrating to unified mode.
Q. Are the embedded access points upgradable to unified mode in the field?
A. Yes, the access points deployed in autonomous mode may later be upgraded in the field to unified mode. See the requirements directly below.
Q. What is required to operate the embedded access point in unified mode?
A. Unified mode is supported on the Cisco 880 Series only. The host router must have the Advanced IP Services feature set in order to enable unified mode for the embedded access point. The access point's boot image type must be configured on the host router to enable unified mode. After this enable command-line interface (CLI) is invoked, the access point must be rebooted in order to go to unified mode. Make sure that the wireless LAN controller is running version 5.1 or later.
Q. How is the software on the embedded access point upgraded?
A. The embedded access point runs a separate image from the host router, so the access point image can be upgraded without affecting the host router. The embedded access point is shipped by default with the autonomous image (AP801-k9w7) as well as a recovery image (rcvk9w8) that allows upgrade to unified mode. See online documentation on how to upgrade the access point software.
Q. How is the embedded access point managed and configured?
A. If the access point is operating in autonomous mode, there are a few methods to configure it:
• If this is an initial configuration, Cisco Configuration Professional Express (Cisco CP Express) allows minimal configuration such as a Secure Set Identifier (SSID) and encryption for a single SSID.

• For more advanced configurations, a GUI is available at http://x.x.x.x, where x.x.x.x is the IP address of the access point's management interface (BVI).

• The CLI on the access point is also available for configuration by initiating a session from the host router using the CLI "service-module wlan-ap 0 session."

• If the access point is operating in unified mode, the wireless LAN controller offers a GUI to configure the access point.

Το παραπάνω link πρέπει να είναι αυτό που χρειάζομαι. Τουλάχιστον το AP έχει την archive :D

Μπλιάχ, θα γούσταρα τίποτα σε format flash: πρώτα και μετά το download του image. Υποστηρίζει overwrite option τουλάχιστον :)

Oops! Δεν το πρόσεξα. Κοίταξα την σελίδα και δε νομίζω να παραβιάζω κανένα copyright. Αυτή η πληροφορία πρέπει να είναι και public διαθέσιμη. Παραθέτω μόνο το CLI κομμάτι, όπως και το έκανα και δούλεψε για πληρότητα και λύση του παρόντος thread:

Upgrade Cisco IOS through the CLI

This section describes how to upgrade Cisco IOS on an access point through the CLI.

1. Log into the access point through a Telnet session.
2. You can download a new image file and choose to replace the current image or keep the current image.
Note: The latter option is helpful when one of the Cisco IOS files are corrupted. You can work with the access point from the other image in the flash.
3. If you choose to overwrite the existing file, issue the archive download-sw /overwrite /reload tftp: //location/image-name command. The /overwrite option overwrites the software image in flash with the downloaded image. The /reload option reloads the system after you download the image unless the configuration is changed and not saved. For //location, specify the IP address of the TFTP server. For image name, specify the Cisco IOS filename that you plan to use to upgrade the access point. In this example, the command is archive download-sw /overwrite /reload tftp: //10.77.244.194/c1240-k9w7-tar.124-10b.JA3.tar. As mentioned earlier, do not change the name of the Cisco IOS file. Leave it as the default. You find these logs during the successful file transfer:

4. If you choose to keep the existing file, issue the archive download-sw /leave-old-sw /reload tftp://location/image-name command. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message is displayed.
5. The AP downloads the Cisco IOS file specified from the DHCP server and reloads with the new software.

Verify

On the TFTP server, check to see if you receive logs about this file transfer. If you use tftpd32 as your TFTP server software, you can see these logs for a successful transfer of the Cisco IOS file to AP:


Read request for file <c1240-k9w7-tar.123-8.JEA2.tar>. Mode octet [18/08 17:10:14.562]

Once the new image is downloaded, the access point automatically reloads. At this time, the connection to the access point is lost. Login to the AP again. On the GUI, use the System Software menu in order to verify if the new software is loaded. If you use the CLI, you can check this with the show version command. Look at the first line that reads Cisco IOS software in order to check to see if the AP has the upgraded image.

Τέλεια! Αυτό που έκανα upgrade είναι lightweight image και δε δουλεύει τίποτα. Πάει το autonomous μου και δεν βλέπω να υπάρχει επιλογή για να το κατεβάσω πουθενά από την σελίδα του router. Μόνο το lightweight έδινε.

Τελικά μόνο με search κατάφερα να ξετρυπώσω το autonomous image και με τις παρακάτω επιλογές το εγκατέστησα, αφού έδωσα πρώτα ένα "service-module wlan-ap 0 reset bootloader" να πάρω ap prompt (παίζει και το ESC φαντάζομαι όπως λέει):

Using the CLI

Follow the steps below to reload the wireless device image using the CLI. When the wireless device begins to boot, you interrupt the boot process and use boot loader commands to load an image from a TFTP server to replace the image in the wireless device.

Note Your wireless device configuration is not changed when using the CLI to reload the image file.

Step 1 Open the CLI using a connection to the wireless device console port.

Step 2 Reboot the wireless device by removing power and reapplying power.

Step 3 Let the wireless device boot until it begins to inflate the image. When you see these lines on the CLI, press Esc:


Loading "flash:/c350-k9w7-mx.v122_13_ja.20031010/c350-k9w7-mx.v122_13_ja.20031010"
...###########################################################################
################################################################################
################################################################################
####################


Step 4 When the ap: command prompt appears, enter the set command to assign an IP address, subnet mask, and default gateway to the wireless device.

Note You must use upper-case characters when you enter the IP-ADDR, NETMASK, and DEFAULT_ROUTER options with the set command.

Your entries might look like this example:


ap: set IP_ADDR 192.168.133.160

ap: set NETMASK 255.255.255.0

ap: set DEFAULT_ROUTER 192.168.133.1


Step 5 Enter the tftp_init command to prepare the wireless device for TFTP.


ap: tftp_init


Step 6 Enter the tar command to load and inflate the new image from your TFTP server. The command must include this information:

•the -xtract option, which inflates the image when it is loaded

•the IP address of your TFTP server

•the directory on the TFTP server that contains the image

•the name of the image

•the destination for the image (the wireless device Flash)

Your entry might look like this example:


ap: tar -xtract tftp://192.168.130.222/images/c350-k9w7-tar.122-13.JA1.tar flash:


Step 7 When the display becomes full, the CLI pauses and displays --MORE--. Press the spacebar to continue.

Note If you do not press the spacebar to continue, the process eventually times out and the wireless device stops inflating the image.

Step 8 Enter the set BOOT command to designate the new image as the image that the wireless device uses when it reboots. The wireless device creates a directory for the image that has the same name as the image, and you must include the directory in the command. Your entry might look like this example:


ap: set BOOT flash:/c350-k9w7-mx.122-13.JA1/c350-k9w7-mx.122-13.JA1


Step 9 Enter the set command to check your bootloader entries.


ap: set

BOOT=flash:/c350-k9w7-mx.122-13.JA1/c350-k9w7-mx.122-13.JA1

DEFAULT_ROUTER=192.168.133.1

IP_ADDR=192.168.133.160

NETMASK=255.255.255.0


Step 10 Enter the boot command to reboot the wireless device. When the wireless device reboots, it loads the new image.


ap: boot
