Take-over of network frame handling in a computing environment

摘要

A first component of a computing environment receives, from a physical network adapter of the computing environment, a request that the first component take over processing of network frames directed to network frame address(es) associated with a second component of the computing environment. The first component register the network frame address(es) for processing of network frames directed to the network frame address(es). Based on the first component receiving from the physical network adapter a network frame directed to a network frame address of the network frame address(es) associated with the second component, the first component processes the received network frame, in which the network frame is provided to the second component via an inter-component link between the first component and the second component.

1. A computer program product, comprising:
a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising: receiving, from a physical network interface card of a computing environment, by a first virtual switch of the computing environment, a request that the first virtual switch take over processing of network frames received from the physical network interface card, the network frames being provided to the physical network interface card by a physical switch of a physical link aggregation group of which the physical network interface card is a part and being directed to one or more network frame addresses associated with a second virtual switch of the computing environment, wherein the first virtual switch and the second virtual switch share a single physical port of the link aggregation group, the network frames being link aggregation group traffic from the physical switch of the physical link aggregation group to the physical network interface card through the single physical port; registering the one or more network frame addresses with the first virtual switch as one or more take-over network frame addresses, for processing of network frames directed to the one or more network frame addresses; and based on receiving, by the first virtual switch, from the physical network interface card, a network frame directed to a network frame address of the one or more network frame addresses associated with the second virtual switch, and based on determining that the network frame address is registered with the first virtual switch as a take-over network frame address, processing the received network frame by the first virtual switch, wherein the processing comprises providing the network frame to the second virtual switch via an inter-component link between the first virtual switch and the second virtual switch.
