US Patent 10432426 Port mirroring in a virtualized computing environment

Example methods are provided for a network management entity to implement port mirroring in a virtualized computing environment. The method may comprise configuring a port mirroring session between a source virtual port and a destination virtual port. A source host may be configured using source session information and a destination host configured using destination session information such that packets passing through the source virtual port are mirrored and sent from the source host to the destination host. The method may also comprise: in response to detecting a status associated with the source virtual port, or the destination virtual port, that requires a reconfiguration of the port mirroring session, generating and send a first instruction to update the source session information at the source host, or a second instruction to update the destination session information at the destination host, or both.
