Cisco SD Access Demystified


One of the Cisco Digital Networking Architecture corner stone concepts is Software Defined Access (or simply, SD Access). It is challenging to describe what Cisco SD Access is, in just a few words, without it sounding like a marketing pitch. The message I have been receiving from Cisco is that SDA is the (only) way that we should be designing our future networks.

30 Technical WiFi Thoughts


George has provided us with a pretty concise list of a lot of the gotchas in WiFi design. There's a lot in there that's absolutely correct - with George's permission, I have reproduced the full text of his article. There's a few points in here that really jump out in terms of how to properly design a WiFi network - we attend sites to remediate networks that don't work properly and it never ceases to amaze me that the basic rules just aren't followed. This can be on big installs too - have a read through George's notes of wisdom below.

In this blog, we’ll take a quick look at the functions, features and power level comparisons for Cisco APs. These are the Z domain (on the newer) and N domain (on the older) APs, which are what we use in the Australian market. As regulations have changed, so the powers the APs can transmit have been allowed to increase.

KRACKs (Key Reinstallation Attacks)


Anyone working with WiFi will have heard about the announcement that was made public on October 16, about the discovery of some vulnerabilities (known as KRACK) affecting the security protocols that are used on WPA/WPA2 protected wireless networks. IEEE 802.11i, which is the technical term for WPA2 was believed to be secure and unbreakable since its introduction in 2003. This is quite a long time and it is therefore needless to say that the discovery of KRACKs was quite a shock for the whole IT world.

Cisco's ISE 2.X Software Release Lifecycle


Cisco ISE (Identity Services Engine) is an Enterprise grade AAA product that has been around for 7 years. It is the successor to Cisco’s popular and widespread ACS product which has reached the end of sale status. With the introduction of ISE 2.4, Cisco claim to have reached feature parity with ACS and this should accelerate customer migrations of ACS to ISE. Cisco provides migration tools to assist with these migrations, but in many cases it makes sense to re-architect the system to allow efficiencies to be gained. IPTel has performed a number of complex migrations from ACS to ISE to ensure business continuity with minimal downtime.

Cisco Smart Licensing


Cisco Smart Licensing is a cloud based service that enables organisations to manage their licences from one central location, allowing dynamic allocation to all supported end devices. What’s great about this model is that it allows for a more efficient use of licenses while reducing the overhead of manual management and tracking.
