Unlike a central load balancer, a Distributed Load Balancer (DLB) instance is attached to virtual interfaces of a VM group.
Add a policy group consisting of VMs. For example, such a VM group can be related to the App tier that receives requests from a VM on the Web-tier.
- ♦ Run
"connectivity_path" : "/infra/domains/default/groups/<clientVMGroup>",
"enabled" : true,
"size" : "DLB",
"error_log_level" : "Debug",
"access_log_enabled" : false,
"resource_type" : "LBService",
"display_name" : "mydlb"
A DLB instance is created and attached to the VM group. The DLB instance created on the Web-tier is attached to all the virtual interfaces of the Web-tier VM group.
- If the connectivity path is set to Null or Empty, the DLB instance is not applied to any transport nodes.
- If the connectivity path is set ALL, all virtual interfaces of all transport nodes are bound to the DLB instance. One DLB instance is applied to all the virtual interfaces of the policy group.
- size: Set to value DLB. As each application or virtual interface gets an instance of DLB, there is just a single size form factor of the DLB instance.
- enabled: By default, the created DLB instance is enabled. You cannot disable the DLB instance.
- error_log_level: Supported levels are Debug, Error, and Info. By default, log level is set to Info. To get verbose logs, set the level to Debug.
What to do next
After creating a DLB instance, log in to the NSX Manager, go to . View details of the DLB instance.
