How to configure SNMP settings on NSX Manager and Edge nodes

Products

• VMware NSX

Issue/Introduction

• SNMP is not started/configured by default after NSX installation.
• A consistent means of configuring SNMP settings (community, username/password, trap destination) across NSX manager and edge nodes is desired.
• The NSX SNMP framework enables monitoring of both system-level entities (for example, disks and interfaces on NSX Edge appliances) and logical entities (for example, VPN tunnels and logical switches) from an SNMP manager.

Environment

VMware NSX-T Data Center 3.x
VMware NSX 4.x

Cause

When Node Profiles are active, they automatically overwrite local CLI configurations for SNMP. Any manual changes made directly via the CLI are non-persistent and will disappear.
To prevent a node from accepting the node profile, use the CLI command set node central-config disabled on that node.

Resolution

1. With admin privileges, log in to NSX Manager.
2. Select System > Fabric > Profiles.
3. Click the Node Profiles tab.
4. Click All NSX Nodes in the Name column.
5. Configure SNMP Polling/Traps for v2c or v3 as per your requirements 
6. To verify the service status on the node via NSX CLI, run:
   get service snmp
