Cisco 2504 FUS Update for 7.4 Code

" Cisco Unified Wireless Network Field Upgrade Software (FUS), Release 1.8.0.0, is a special AES package that performs various system-related component upgrades for Cisco Wireless LAN 2500 Series Controllers. If you are using a Cisco 2500 Series Controller and you upgrade to the 7.4.100.0 controller software release and intend to use the Application Visibility and Control (AVC) and NetFlow protocol features, you must install Cisco Unified Wireless Network Field Upgrade Software, Release 1.8.0.0. This release is not required if you are using other controller hardware models." http://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_1_8_0_0.html This definitely worth noting if you are upgrading to 7.4, as the new AVC features will not work without it. Also, it is well worth attaching a console cable whilst doing the upgrade as it takes a long time (around 30 minutes). Without the console, you'll be sitting there with your fingers crossed, breaking out...

Apple TV Services

I've been taking a look at the Bonjour protocol in general recently due to some requirements I have been looking at for customers. The availability of Bonjour gateways from the likes of Cisco and Aerohive certainly make things a lot easier to provide access to Bonour services without having to jump through lots of multicast-over-wireless hoops. One area of particular focus has been Apple TV. It seems to be quite a popular device with execs who want to be able to mirror their iPad on to a meeting room projector. There are some great tools that allow you to browse the services that are available on a network. I have been using  Bonjour Browser for Windows , though other Mac equivalents are also available. When looking at the services available from an Apple TV, I see the following services advertised: _airplay._tcp. _raop._tcp. _sleep-proxy._udp. _touch-able._tcp. _appletv-v2._tcp I was interested to know what each of these services does. So, here it w...

Apple iTunes Services

This is just a quick note about some Apple services you may see advertised using mDNS when you are implementing a Bonjour gateway on your wireless network. I've been investigating which services might be visible when the iTunes application is being run on computers that are connected to the wireless network. From my testing, I have only been able to find 2 services you may come across when using iTunes ( this just considers the iTunes application and does not include any other services from Apple TV, printers etc .): _daap._tcp.local. _apple-mobdev._tcp.local. _daap._tcp.local. This service becomes available when you choose the option to share your library on the local network Share library on local network: The service advertisements are generated by the iTunes software on the computer (and hence originate from the computer itself) to be detected by other devices/computers across the network _apple-mobdev._tcp.local. This service becomes visible when...
