Environment

VMware NSX-T Data Center 

Cause

This issue can occur if there are no regular maintenance of NSX-T nodes. 

Resolution

To resolve the issue, reboot the NSX manager node. 

Once the reboot is completed, check the status of the SNMP service by running the command get service snmp as admin user or /etc/init.d/vmware-snmpd status as root user.


Note: If the issue persists after the reboot, collect the NSX manager node support bundles and open a support request with Broadcom by following Creating and managing Broadcom support cases.

Additional Information

It is recommended to regularly upgrade the NSX to the latest version to benefit from new features, security patches, and improved stability, as VMware regularly releases updates.
