Use this command to enter into VPC configuration mode and creates a VPC domain with the specified domain-id. Only one VPC domain can be created on a given device. The domain-id of the VPC domain should be equal to the one configured on the other VPC peer with which this device wants to form a VPC pair. The configured VPC domain-ids are exchanged during role election and if they are configured differently on the peer devices, the VPC does not become operational.
The administrator needs to ensure that the no two VPC domains can share the same VPC domain-id. Domain-id is used to derive the auto-generated VPC MAC address that is used in the actor ID field in the LACP PDUs and STP BPDUs sent out on VPC interfaces. When two VPC domains have the same domain-id, it leads to the same actor IDs and results in LACP convergence issues and STP convergence issues.
The range of domain id is 1-255.
