How to Force Delete a Stale Logical Segment in NSX 3.x

Manish Jha

I ran into a problem recently when disabling NSX in my lab where I couldn’t remove a logical segment. This logical segment was previously attached to NSX Edge virtual machines. The logical segments still had a stale port, even after the Edge virtual machines were deleted.

Any attempt to delete the segment through UI/API resulted in the error “Segment has 1 VMs or VIFs attached. Disconnect all VMs and VIFs before deleting a segment.” 

GUI Error

API Error

So how do I delete the stale segments in this case? The answer is through API, but before deleting the segments, you must delete the stale VIFs. 

Follow the procedure given below to delete stale VIFs.

1: List Logical Ports associated with the Stale Segment

Quick Tip: Configure NSX Manager GUI Idle Timeout

Manish Jha

The NSX Manager Web-UI has a default timeout of 1800 seconds. i.e., the NSX Manager UI will time out after 30 minutes of inactivity. This timeout looks reasonable for a production deployment, but since security is not an issue in lab settings, you might want to change it to a little bit higher. On top of that, it is annoying to get kicked out of the UI after 30 minutes of idle session.

In this post, I will demonstrate how you can change the timeout value.

Run the command get service http to see the currently configured value:

Run the command set service http session-timeout 0 to fully remove the session timeout.… Read More

Redeploy NSX Edge Gateway Using Rest API

Manish Jha

In this post I will demonstrate how to redeploy edge gateway in vCloud Director using Rest API

Disclaimer: This is not any fancy post and I am going to perform very simple task here. Most of you may be already aware of this. This post is for those who are new to API and also a reference post for me for future.

Lets get started.

We have to follow below steps for redeploying an edge gateway using API calls

Step 1: Generate Auth Token

# curl -sik -H “Accept:application/*+xml;version=5.6” -u “admin@system” -X POST https://vcd-b.alex.local/api/sessions | grep auth
Enter host password for user ‘admin@system’:

x-vcloud-authorization: 3fc8a5425f804c9d94eeff04e0272ed7

Step 2: Get Org UUID

# curl -sik -H “Accept:application/*+xml;version=5.6” -H “x-vcloud-authorization:3fc8a5425f804c9d94eeff04e0272ed7” -X GET https://vcd-a.alex.local/api/org/

Step 3: Get vDC UUID

# curl -sik -H “Accept:application/*+xml;version=5.6” -H “x-vcloud-authorization:3fc8a5425f804c9d94eeff04e0272ed7” -X GET https://vcd-a.alex.local/api/org/58d92de4-4aa5-4a14-9b39-28e1de5e9809… Read More
