Cisco Catalyst 9400 Switches – A new Launch
As in my earlier article i talked about the new launch of the Cisco catalyst 9300 and explain the features of that catalyst switch. Now I am going to talk about the other 2 series which Cisco launches. Cisco understand the requirement of the market and also competing with the other vendors for Next generation networks like SDN where open APIs can be used to stitch third party applications.
Cisco come up with the solution for the campus where they are going to deploy the fabric network on the top of traditional IP network. I will come up with another article where I can explain the architecture of the SD-Access network for the campus network designed by Cisco Systems.
With the launch of Cisco 9300, 9400 and 9500 cisco is running ahead in the field of enterprise network architecture. For Cisco catalyst 9300 please check the below mentioned link

Converge your network with priority flow control (PFC)
Back in April, we talked about a feature called Explicit Congestion Notification (ECN). We discussed how ECN is an end-to-end method used to converge networks and save money. Priority flow control (PFC) is a different way to accomplish the same goal. Since PFC supports lossless or near lossless Ethernet, you can run applications, like RDMA, over Converged Ethernet (RoCE or RoCEv2) over your current data center infrastructure. Since RoCE runs directly over Ethernet, a different method than ECN must be used to control congestion. In this post, we’ll concentrate on the Layer 2 solution for RoCE — PFC, and how it can help you optimize your network.
What is priority flow control?
Certain data center applications can tolerate only little or no loss. However, traditional Ethernet is connectionless and allows traffic loss; it relies on the upper layer protocols to re-send or provide flow control when necessary. To allow flow control for Ethernet frames, 802.3X was developed to provide flow control on the Ethernet layer. 802.3X defines a standard to send an Ethernet PAUSE frame upstream when congestion is experienced, telling the sender to “stop sending” for a few moments. The PAUSE frame stops traffic BEFORE the buffer Continue reading

OpenVPN 2.3.17 on OpenBSD 6.0
On Jun 21, the OpenVPN team released an update for the 2.3.x and 2.4.x branches that resolved some newly discovered security vulnerabilities. The OpenVPN team recommends that users “upgrade to OpenVPN 2.4.3 or 2.3.17 as soon as possible“.
OpenBSD 6.0–which was released Sep 1 2016 and is still receiving security updates to the base system as per OpenBSD’s policy–shipped with a package for OpenVPN 2.3.11. Below you will find a patch and instructions for using the ports system to upgrade to version 2.3.11. Note that if you’re running OpenBSD 6.1, the ports tree has been updated to 2.4.3 so all you need to do is “cvs up” and “make install”.
Instructions:
- Follow the OpenBSD FAQ for instructions on how to download, verify, and extract the ports tree on your machine.
- Then:
% cd ports/net/openvpn
% patch < ~/openvpn-2.3.17p0.diff
% make installOriginal article: OpenVPN 2.3.17 on OpenBSD 6.0
