In my previous post I explained how to quickly interpret a network capture on ESXi by using pktcap-uw and tcpdump-uw. This works great to get some information at a glance. But what if you require some further analysis? Well, then Wireshark is probably your tool of choice. Check out the rest of this blog post to learn how to set up remote capturing so you don’t need temporary storage on ESXi for your capture files.
As a vSphere admin you are sometimes tasked with investigating network issues. You don’t always have VM access so you need to diagnose at the ESXi level. Now as some of you may know quickly gaining insight in VM network traffic by capturing it on the ESXi level is a rather complex task. The tool at your disposal for capturing VM traffic is called pktcap-uw and one of it’s biggest shortcomings is that it doesn’t interpret the packets.
Introduction Recently I have been upgrading one of my test environments from NSX 3.1.2 to 3.2.1 and have come across a couple of issues. This time it seems like there is one Tier 1 GW in my environment that is Read more…
Introduction Recently I have been upgrading one of my test NSX-T labs. In this particular lab environment the scenario was upgrading NSX-T 3.1.2.1.0 to 3.2.3.1.0. NSX-T environments are upgraded in phases and the first (actually second) phase is upgrading the Read more…
Recently I upgraded a NSX-T multisite deployment. Unfortunately following the upgrade on one of the local sites it failed to display that site’s status on the system overview page.
NSX-T makes it very easy to deploy virtual edge transport nodes using the NSX manager. Simply fill in a couple of variables and it will make sure a new node is created by importing an OVF file on your vSphere environment. But once deployed not all settings can be changed. This is where the NSX manager API can be a useful tool.
Introduction If you have worked or are working with NSX for vSphere (NSX-V) like me you are probably aware of the known bug that is present on some olders versions of NSX-V. Even the VMware Interoperability Matrix has a remark Read more…
