Changing NSX-v controller passwords is a question which comes up quite a bit with customers. Often because the passwords chosen at deployment time are either too complex to type in on a VM console session, or on the other end of the spectrum, they were set to something easy to type […]
One of the features of NSX-v is the ability to create a Layer 2 VPN between 2 NSX-v Edge Services Gateways (ESG from now on). But what happens if there is no NSX-v at the destination where you would like to extend your Layer 2 network. As of NSX-v 6.1.0 […]
Whilst working with a customer recently, we encountered a situation recently where we were required to run a packet capture on a VCSA (vCenter Server appliance) version 6.0. Being a Linux appliance underneath, the tool to use is tcpdump, but by default tcpdump is not actually installed by default. There […]
On various engagements I am involved with, I often need to produce some code to add or delete objects from NSX-v. These objects in general are things like IP Sets, MAC Sets, Security Groups, Security Tags, Services, Service Groups, Security Policies and even deleting the FW rulebase itself. Until recently […]
Recently on a customer site we had a peculiar scenario where we were deploying a VM into a NSX environment via vRA and the operation was failing due to an unknown reason. However, we noticed that the IP address that vRA had allocated for the new VM was still responding […]
Its well documented that the only way to configure syslog settings on NSX-v controllers is via the REST API. One of the things I find myself constantly doing over and over again on customer engagements is configuring syslog servers details on the NSX-v controllers, whether its because I am at […]
The Broadcom bnx2x NIC driver for VMware ESXi when installed on a ESXi 5.5 host is often an overlooked component when working with VMware NSX. If you have one of the Broadcom NICs which supports VXLAN offload and uses the bnx2x driver, it is important to choose the correct driver […]
Often when working in customer environments, there is a requirement to define security group members which are not virtual machines within the visualised environment. To achieve this, these security group members must be defined as an IP Set. The IP Set can then be included as an object in a […]
Whilst working on a vCloud Automation Center integration with NSX-v this evening, I noticed a strange error which had appeared in the logs in regards to the data collection for Network and Security Inventory. The Network and Security Inventory data collection was displaying the time the data collection last completed, […]
So following on from my previous post (NSX-v: ESG Packet Capture), today we run through how to do a packet capture on one of your NSX Controllers. Why would you want to do this I hear you ask? Well I had a situation recently where I had some unexplained behavior […]
