Earlier this year, Cisco announced new stackable switches that put them in a better position to compete with some of the lower-cost competitors such as HP and Dell. These switches still incorporate the features that set Cisco above their competition but also offer a more competitive price point. These switches come in three product lines - the Catalyst 2960S, Catalyst 3560X, and Catalyst 3750X - and offer features such as 24 or 48 ports of Gigabit Ethernet, Power over Ethernet, advanced stacking capabilities, 10Gb uplinks, and redundant power options in the highest-end configurations. To discuss how these switches can fit into your environment, please contact your Simpler-Webb account rep.

I had originally planned on a daily blog post about Cisco Live! But that rapidly fell by the wayside as it was super busy, information overload, and long, tiring days. That said, it was definitely worth it, and I was able to learn a great deal about the Cisco Nexus switching architecture, network management, network security, and Cisco Unified Wireless Networking. I also had the opportunity to take (and pass!) the test for the Cisco Certified Network Associate (CCNA) Wireless certification and one of the four tests for the Cisco Certified Network Professional (CCNP) Wireless certification. The test for the CCNP Wireless certification also renewed my CCNP, CCDP (design) and CCSP (security) certifications which were coming up for renewal in a couple months. If you haven’t been to Cisco Live!, it’s a great event that provides a lot of opportunity to learn about new technologies Cisco is working on or has just released, as well as existing technologies. If you have the opportunity to go, I highly recommend it!

Mozilla has released an update to it's popular firefox browser. The updated version (3.6.4) addresses numerous security vulnerabilities and improves stability by isolating browser plug-ins within the browser. The update will be applied automatically for most users using the auto-update feature within the browser or can be download directly from
http://www.mozilla.com.
The browser isolation feature in this update will prevent add-on's, such as Adobe flash or Microsoft silverlight, from crashing the entire browser when problems occur within specific plug-ins. This architecture is becoming an industry standard among most browsers.
When updating your firefox browser it's also a good time to update your Adobe flash player. The current version is 10.1 and you can update to it directly from this link:
