Data center bridging (DCB) Ethernet enhancements are available to improve Ethernet networking and management in data center environments. DCB is a framework that defines the enhancements that are required for switches and endpoints. DCB includes the following features:
PG, also knows as ETS, which is a priority grouping specification that provides bandwidth management as well as a scheduling algorithm for various traffic classes on a converged link.
PFC, which is an enhancement to the existing Ethernet-pause protocol, that allows o-drop packet delivery for certain traffic classes.
This release of the SEFOS DCB feature supports DCB version 1.0.1, as specified by the DCB task group.
Refer to the Sun Ethernet Fabric Operating System DCB Administration Guide for more information about this feature. For information about supported DCB commands, refer to the Sun Ethernet Fabric Operating System CLI Base Reference Manual.
