NSX-v Communications Diagram

Below is diagram to visually see the communications (protocol/port) of the NSX-v (6.2.x) components. The focus of the diagram is from an NSX-v viewpoint. Therefore, I haven’t included the comms for vSphere, and it’s relevant components. Continue reading “NSX-v Communications Diagram”

NSX-v Load Balancer Application Rules

Application rules in NSX for vSphere allow you to create advanced load balancing rules which may not be possible with the application profile or services natively available on the Edge Services Gateway (ESG). However, the ESG enables you to add your specific application rules to support your load balancing scenario; application rules are built using HA Proxy syntax.

NSX-V Edge (ESG) Packet Capture

Capturing packets on the NSX Edge is relatively simple, the ESG uses similar capture syntax to that of TCPDUMP with a few minor caveats, which I will cover in this post.
When doing a packet capture, the primary thing to do is to identify the interface you want to capture traffic on and then define the traffic capture filter, which will ensure you only capture the packets that your interested in. This will cut down the noise and leave you with a fairly clean packet capture, however there is no reason you can’t just capture everything. Continue reading “NSX-V Edge (ESG) Packet Capture”

NSX-V Edge: Site-to-Site IPSEC VPN

This post will describe the process of setting up a site-to-site vpn from the VMware NSX Edge to a Cisco Cloud Services Router (CSR) 1000v, although we are using a virtual Cisco router, the process described below could be used for any remote device. In this post we will be configuring the Edge Services Gateway (ESG) via the vSphere Web Client, however, the method of setting up the VPN could easily be automated via the NSX REST API.
