NETWORK WORLD ARTICLE: PRODUCT TEST ALERT 03/25/08 10 Gig access switches: Not just packet pushers anymore Our tests found seven next-generation switches bristle with features that don't exist in many previous models - not just physical features like 10-gigabit Ethernet uplinks but also 802.1X-based network access control authentication, enhanced multicast support, storm control, DoS protection and IPv6 support.Read full story This article is sponsored by Overland How to Manage the Storage Explosion Download Network World's latest Executive Guide today and learn which new strategies and technologies can help you best manage storage demands and meet regulations.

Join at: RELATED EDITORIAL LINKS NAC/802.1X support in access switches is all over the map, 03/24/08 Many switches today support 802.1X authentication, a basic building block in NAC. The key question is what kind of access authenticated users can expect. In the six-test scenarios we developed for this project, we uncovered major differences among products in terms of the conditions under which they'll grant access as well as what sort of access they'll permit. Breaking the standards, 03/24/08 In what's becoming something of a tradition in Network World tests, this project turned up design flaws in two standards: IEEE 802.1X authentication, which we tested in a NAC context, and IETF RFC 3918 covering multicast testing. Features abound in latest and greatest access switch models, 03/24/08 While this test's key takeaway may be the big differences in new features, the good news is that, with a very few exceptions, all switches support the same basic L2/L3 functions . How we tested the switches, 03/24/08 We assessed switches with 10 sets of tests covering L2 and L3 unicast performance; IGMP group multicast capacity; L2 and L3 multicast performance; NAC/802.1X; storm control; power consumption; switch manageability, security, and usability; and switch features. Multicast performance differentiates access switches, 03/24/08 Once upon a time, layer-2 unicast performance tests would have produced by far the most important results, but that's changed. Measuring unicast throughput on all ports, once considered the acid test for access switches, is no longer a major differentiator. Alcatel-Lucent wins green bragging rights in switch test, 03/24/08 With electric bills in large data centers topping $1 million per month, power consumption is a major concern. Using Fluke 322 and Fluke 335 clamp meters, we measured each switch's power draw, both when idle and again when its control and data planes were fully loaded. Most switches help in complying with secure management best practices, 03/24/08 In assessing switch management and security, we sought to answer three questions: Did devices follow current best practices by default? Could users configure switches to follow these best practices? And could switches be wiped clean of any sensitive information before being taken out of deployment? Switch usability centers on CLI comfort zone, 03/24/08 Any assessment of switch usability is necessarily subjective. While there are some objective measures that can be applied (for example, it might take 17 steps to enable SSH on one switch, and only five on another), usability assessments ultimately come down to what's most comfortable for any particular user.
