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.

Configuring units

Common

• Enter admin mode
  • Gain privileged access:

   enable

• Enter config mode.
  • Enter (configuration) context:

   configure terminal

show dot11 network-map

• Show live configuration:

show running-config

• Commit live configuration as the new default:

write memory

• Show neighbouring Cisco equipment:

show cdp neighbors [detail]

• Show interface status:

sh ip interface brief

• Get an idea of your network map:

bridge-e#sh dot11 associations


== 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:

1. Find an equivalent piece of hardware that is working and has the feature
2. Get both devices on the network, use an ethernet cable for preference
3. Upload its current image, if it's not already there
4. 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 ...
