How to Stack HPE/Aruba 2920 Switches – HP Networking Series Part 4

Stack

The 2920 series switches from HPE/Aruba has a special feature that no other switches in the old ProCurve/E-Series line-up has; dedicated stacking interfaces. On other HPE switches, stacking merely facilitates “simplified” management, by allowing you to manage any switch in the stack from the stack commander’s CLI. On the 2920 series however, you can use dedicated stacking interfacing, giving you 2 20 Gbps links to other switches in the stack and merging two to four switches into one coherent switch. This is quite similar on how stacking works on some Cisco models, but the specialized stacking interfaces gives you higher speeds between the members. In this article, I’ll show you have to set up the commander switch and how to add switches to the stack once it’s created. I’ll also go into how it affects the configuration of the switches, which is quite crucial if you want to stack switches that are already in production.

4G finally available in the iPad 4 and Mini, in Finland

According to the latest iOS update from Apple, version 6.1, expanded LTE support is one of the many new features. While this doesn’t probably sound very amazing for the American readers, here in Finland for example we’ve had almost every bigger city covered by 4G for over a year now, but sadly all Apple devices have been incompatible with the carrier frequency used here in Europe.

According to Apples LTE site, iPad 4 and Mini users should get support for 4G from all the three major carriers here in Finland just by upgrading. Sadly, iPad 3 users are still stuck with 3G, but that’s no great surprise, since fixing missing carrier frequency support isn’t something that you’d easily fix with a software patch.
