Config snippets : Cisco : Turning lightweight Cisco 1142n into autonomus Cisco 1142n AP

-

So, finally I got 6 brand new Cisco 1142n wireless access points. They all are lightweight access points, which means that more less Wireless Controller is required to get them to work. Unfortunatelly due to many circumstances I have purchase of Wireless Controller delayed, so for now have to turn all of those into autonomus wireless devices. That means that IOS has to be replaced on those devices to allow 1142n be fully configured.

  • Original software which came on devices was: c1140-rcvk9w8-mx.
  • New software I had to deploy on all of them to make them autonomus is: c1140-k9w7-tar.124-25d.JA1.

But how the whole process happenes? Here are all steps I took to make lightweight AP become autonomus wireless access point:

Config snippets : Cisco : First time 881w ISR with AP configurarion

-

When I got cisco 881w first time it was interesting experience. This device presented new concept which was different to model I knew so far, which is 871w. In 881w router module and wireless module are separated. With that being said, router configuration and access point configuration is separated as well. Also, each module (router and access point) has own IOS:

  • c880data-universalk9-mz.152-1.T1 – router IOS
  • ap801-k9w7-mx.124-21a.JA1 – access point IOS

As usual, first I connected device to console cable and attempted to configure it. Not being familiar with new concept it was a bit of a failure 🙂 So, eventually had to refer to documentation to find out what’s going on. Problem which came up was, how to access wireless module to configure it or even check if it’s there 🙂

So, finally after I did apply reading ability and spent few minutes with Cisco documentation I was able to access wireless module and configure it to provide wireless services in the air. Here is how that happend:

Recently I was wondering how to list all available drives in Windows 7 PE Command Prompt. That happened to me when stuck in PXE boot command prompt window trying to find out what letter is assigned to USB stick I just plugged in. It looks like it’s not quite straightforward activity 🙂

Config snippets : Configuring static IP address on Debian 6.0

-

Just quick config snippet for Debian 6.0 which I came across when setting up few Debian Linux 6.0 virtual machines for recent network LAB. By default network adapter is set to get IP address from DHCP.

/etc/network/interfaces – dynamic IP address configuration

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface auto lo iface lo inet loopback
# The primary network interface allow-hotplug
eth0 iface eth0 inet dhcp
