Configuring OpenSwitch

The following configuration enables sFlow monitoring of all interfaces on a white box switch running the OpenSwitch operating system, sampling packets at 1-in-4096, polling counters every 20 seconds and sending the sFlow to an analyzer (10.0.0.50) on UDP port 6343 (the default sFlow port): 
switch(config)# sflow collector 10.0.0.50
switch(config)# sflow sampling 4096
switch(config)# sflow polling 20
switch(config)# sflow enable
A previous posting discussed the selection of sampling rates.  Additional information can be found in the OpenSwitch sFlow User Guide.

See Trying out sFlow for suggestions on getting started with sFlow monitoring and reporting.

iPhone 7 to feature radically new home button design

The lack of a traditional 3.5mm headphone jack may not be the only big design change Apple introduces when it rolls out the iPhone 7 later this year. According to sources, and most recently a report from analysts Cowen and Company (via Business Insider), the home button on the iPhone 7 will be like nothing Apple has ever shipped before.Specifically, the iPhone 7's home button may sit flush with the entire device itself and will not be able to be pressed down. Instead, Apple will incorporate Force Touch technology such that when a user taps the home button, it will trigger a series of vibrations that will mimic the feeling of a pressed button.To read this article in full or to leave a comment, please click here

And having used Apple's MacBook, I can attest that Apple's scheme of haptic feedback truly does mimic the feeling of a physical button.To read this article in full or to leave a comment, please click here

Avaya’s edge network adapter is an IoT onramp

Avaya today released the 1.0 version of its Open Networking Adapter (ONA), a device the size of a deck of cards that plugs into any Ethernet-enabled machine and automatically connects it to a broader network while enforcing strict security policies on network traffic.Avaya’s ONA is a network edge device meant to usher in an era of connected devices to create an internet of things environment. The first use case Avaya is targeting with ONA is the health care industry with a custom software GUI for controlling the ONAs.+MORE AT NETWORK WORLD: Top 5 Storage vendors shows a massive shift to the cloud | Why Brexit could cause major data privacy headaches for US companies + ONA is a small proxy device with two Ethernet inputs on each end. The aluminum casing holds a dual core CPU running Open vSwitch. It’s equipped with two-factor authentication so that when the device is on boarded for the first time there’s a key that’s shared between the ONA and a software defined networking (SDN) controller to verify it. The device doesn't store any data, so if it were stolen, it would be a brick without the 2FA connection. “It Continue reading
