| == Capabilities ==
| | [[Wireless-New|Wireless config page]] |
| | |
| These radios operate in the 2.4Ghz or 5 Ghz microwave band, and support 802.11b/g wifi connections.
| |
| We have many units:
| |
| 12(?) x omnidirectional, indoor units, two with standard antennas, two with (high-gain?) antennas.
| |
| (Aironet 1200 series)
| |
| | |
| Some of the 1200 series have two radios installed: The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.
| |
| | |
| 6x weather-proofed point-to-point units with highly-directional integrated antennas,
| |
| with separate (indoor) breakout boxes.
| |
| (Aironet 1300 series)
| |
| | |
| == Controlling the units ==
| |
| | |
| These wireless base-stations are sophisticated computers in their own right. They run the
| |
| Cisco IOS operating system: specifically, version 12.3.
| |
| By default, they can be controlled via a serial console, using the special
| |
| cyan RJ45-DB9 serial cable provided or the cyan USB-serial cables.
| |
| | |
| They can also be controlled via telnet and have a web interface which is occasionally useful. By default, configured to use DHCP to
| |
| acquire their own IP address, but we have over-ridden this for obvious reasons (it's hard to telnet to a device when you don't know what its address is ...).

| === Removing an ssid ===
| |
| Some images set up the _tsunami_ ssid on factory reset, to remove it:
| |
| (from configure mode)
| |
|
| |
| <nowiki>
| |
| ap(config)#interface dot11Radio 0
| |
| ap(config-if)#no ssid tsunami

| // if fitted repeat for dot11Radio 1
| |
| ap(config)#no dot11 ssid tsunami
| |
| ap(config)#exit</nowiki>
| |
|
| |
| == Factory reset ==
| |
| === 1200 series ===
| |
| To return the wireless base-stations to factory settings, power off the device, then --
| |
| while holding the 'mode' button down -- power the wireless device back up.
| |
| Continue to hold the 'mode' button down for a few seconds, then release.
| |
| === 1300 series ===
| |
| If you can login (enable):
| |
| *Enter <code>erase nvram</code> to erase all NVRAM files including the startup configuration.
| |
| *Enter <code>Y</code> when the following CLI message appears: <code>Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]</code>.
| |
| *Enter <code>reload</code> when the following CLI message appears: <code>Erase of nvram: complete</code>. This command reloads the operating system.
| |
| *Enter <code>Y</code> when the following CLI message appears: <code>Proceed with reload? [confirm]</code>.
| |
| If you can't login, try '''really hard''' to log in. Otherwise:
| |
| *Open the CLI with a Telnet session or a connection to the bridge console port.
| |
| *Reboot the bridge by removing and reapplying power.
| |
| *Allow the bridge to boot until the command prompt appears and the bridge begins to inflate the image.
| |
| *Press ESC when you see lines that are similar to these on the CLI:
| |
| <nowiki>Loading "flash:/c1310-k9kw-7mx.v122_15_ja.200040314-k9w7-mx.v122_15_ja.20040314"

| |
| Note: In order to access the boot loader, you must press ESC twice. But this action depends on the terminal-emulation software that you use.
| |
| Messages that are similar to these appear:
| |

| -----------
| |
| | |
| At Odyssey E1, 2013, bridge-[a/b] and the field-ap were all configured and test-deployed:
| |
| | |
| * bridge-a was propped up on a desk in GOD
| |
| * bridge-b was propped up on a box outside the bar, in the ~middle of the IC field.
| |
| | |
| This was an initial test, but it proved to be unexpectedly successful. Despite there being in the way:
| |
|
| |
| * Most of GOD
| |
| * A wet hedgerow
| |
| * Several (dampened) tents
| |
| * A number of people milling about
| |
| * A fair distance
| |
| | |
| ... a solid signal could be established between the two bridge units, despite not having
| |
| done any careful alignment. (Perhaps we were just lucky?)

Connecting
Windows XP
Use Hyperterminal to connect to a unit:
-> Use 9600 baud, no parity, 1 stop bit, and disable hardware flow control.
OSX/Linux
There should be a USB/Serial cable in the box. Clive will also have one in his bag of stuff. But if you lose his, it will be painful ...
Find the port number in terminal:
$ ls -ltr /dev/*usb*
crw-rw-rw- 1 root wheel 21, 2 7 Apr 16:33 /dev/tty.usbserial-AH0668GD
crw-rw-rw- 1 root wheel 21, 3 7 Apr 16:33 /dev/cu.usbserial-AH0668GD
or
matt@merple:~> ls -ltr /dev/ | grep -i usb
crw-rw---- 1 root dialout 188, 0 Sep 13 21:11 /dev/ttyUSB0
matt@merple:~>
You can use screen to connect:
$ screen /dev/tty.usbserial-AH0668GD 9600
Personally, Clive hates using screen, so has downloaded and installed a small cli serial emulator. If you're on a machine it's been installed on, having found the port you want, you connect using:
serial /dev/tty.usbserial-AH0668GD 9600
Log in
If you've got things right, then if you have the cable plugged in when you turn a wireless
base-unit on, you should see boot-time messages start to scroll past for about a minute after
power-on.
Press <ENTER> when prompted to bring up control menu.
Prompt is displayed as: ap> -- or, if the device has been given a different hostname, either manually
or via DHCP, then it will appear as: hostname>
Pressing '?' will display a list of commands.
<TAB> will auto-complete unambiguous partial commands.

== Updating the operating system --- Here be dragons ==
Some problems Clive has been having with some of the devices have been resolved by updating to a more recent version of IOS. (Yes, Cisco also call their OS IOS. In fairness, they were there first: [https://blogs.cisco.com/news/cisco_and_apple_agreement_on_ios_trademark “Cisco has agreed to license the iOS trademark to Apple for use as the name of Apple’s operating system for iPhone, iPod touch and iPad. The license is for use of the trademark only and not for any technology.”])
There should be a running tftp server on favog. It should even have one or more IOS images on it. It'll look like this:
<nowiki> ls -ls /srv/tftpboot/
total 5284
5284 -rw-r--r-- 1 tftp tftp 5408256 Apr 23 19:41 c1310-k9w7-mx.124-10b.JA1.tar
Steps
Simple in principle:
- Find an equivalent piece of hardware that is working and has the feature
- Get both devices on the network, use an ethernet cable for preference
- Upload its current image, if it's not already there
- Download it on the 'broken' one
Upload an image
First, find out what image you have. It'll be the directory with long name starting with your hardware's part number, eg:
bridge-e#sh flash
Directory of flash:/
2 -rwx 2072 Mar 1 2002 00:11:18 +00:00 private-multiple-fs
3 -rwx 1261 Mar 1 2002 00:11:18 +00:00 config.txt
4 drwx 256 Jan 1 1970 00:06:24 +00:00 c1310-k9w7-mx.124-10b.JA1
153 -rwx 70 Mar 1 2002 00:02:33 +00:00 env_vars
155 -rwx 5 Mar 1 2002 00:11:18 +00:00 private-config
7741440 bytes total (2395648 bytes free)
In this case, c1310-k9w7-mx.124-10b.JA1
Copying it is actually fairly easy:
bridge-e#archive upload-sw tftp://10.0.0.18/[the directory name from above].tar
Download an image =
Again, relatively easy:
bridge-f#archive download-sw tftp://10.0.0.18/[the directory name from above].tar
You'll see something along the lines of:

followed by a lot of progress information which may well include wiping the original image out.
Once this is done, restart it. And hope that you've not bricked it ...
