Method, Apparatus, and Computer Program Product for Implementing Bandwidth Capping at Logical Port Level for Shared Ethernet Port

摘要

Bandwidth capping is implemented at a logical port level for a shared Ethernet port. When a physical port of a Host Ethernet Adapter (HEA) is partitioned, a Logical HEA is created for the partition. One or a plurality of Logical Ports (LPorts) is created in the Logical HEA. Each LPort is mapped to a corresponding physical port. During LPAR configuration, a minimum guaranteed speed is specified for the LPort together with the corresponding physical port for the LPort and an optional maximum speed. The specified configuration for the LPort is verified, and the configuration values are stored in the HEA and the HEA dispatches data packets based upon the stored configuration values for the LPort.
