A business case for IPv6: Tax Day
Nephos6 president and CEO Ciprian Popoviciu paints a picture of the extreme business case for IPv6 with this scenario: your last-minute scramble to file taxes on April 15, trying to download the forms online and facing only creeping progress on the status bar. The Internal Revenue Service site is just 61% effective running over IPv6, according to Nephos6's v6Sonar monitoring service. Nearly eight years after the Office of Management and Budget (OMB) mandated that government agencies begin the transition from IPv4, IPv6 still appears to be in the Feds' blind spot. Popoviciu says not even major bureaus like the IRS can expect the protocol to work effortlessly, and shouldn't take the OMB mandate for granted.
Get Popoviciu's explanation of why everyone should care about the government's move to IPv6.
Configure an ERSPAN session to replicate monitored traffic
The solution to extending a Switched Port Analysis session on disparate switches in a Layer 2 network is employing remote SPAN, but this option isn't of much use when you're looking to replicate Layer 2 traffic across a Layer 3 network. PacketLife.net blogger Jeremy Stretch shows how to manage the process with a detailed breakdown of encapsulated remote SPAN (ERSPAN). Configuring an ERSPAN session means transporting traffic in a Generic Routing Encapsulation connection between arbitrary IP endpoints -- a procedure Stretch explains with an example using a Nexus 7000 source and Cisco 7600 destination.

How to configure the VMware Fusion Network Editor
The settings for the Network Editor in VMware Fusion 5.0 Professional aren't the easiest to access, Keith Townsend of VirtualizedGeek points out. For those less accustomed to the Mac interface, he offers a two-minute video with steps for navigating the available preferences, including the option to connect the host computer to the network and enable Dynamic Host Configuration Protocol to create an IP range. Getting into the preferences console may not be the most intuitive process, he says, but once you're there, the setup is fairly straightforward.
