Description: This object indicates the operational state of the bridge domain Member. Operational state of the Bridge domain member is same as the operational state of the underlying service instance. Bridge domain members are configured under service instances and multiple service instances can be attached to a single physical interface defining various kinds of services. Bridge domain members have many to one relationship with interface Indexes. When ifOperStatus of the underlying interface is down, the state of cbdMemberOperState should be down. When ifOperStatus of the underlying interface is up, cbdMemberOperState can be either up or down based on the state of underlying service instance.

'unknown': the bridge domain member is an unknown state.

'up': the bridge domain member is fully operational and able to bridge the traffic. This means that both the physical interface and the underlying service instance are administratively up.

'down': the Bridge Domain member is down and not capable of bridging. This state means either the underlying service instance is down or the interface is down.
