Environment

VMware NSX

Cause

File /config/vmware/edge/dp_ovf_config.json has invalid value of ring size. Valid range is 128 to 4096.

Resolution

This issue is fixed in NSX 4.2.4 and future NSX release.

Workaround : Delete the /config/vmware/edge/dp_ovf_config.json file and restart the dataplane service.

1. Run the following command on the affected Edge Node to restart the dataplane service:

restart service dataplane

2. After the service restarts, verify that the dataplane is operational by executing:

get dataplane

Ensure the command returns valid output without errors.

Additional Information

Impact : Total loss of dataplane forwarding.
