29 Configuring Data Center Bridging Features This chapter describes how to manage the features developed for use in data center environments but often used in a variety of 10G applications. The topics covered in this chapter include: • Data Center Bridging Technology Overview • Priority Flow Control (PFC) • DCB Capability Exchange (DCBX) • FIP Snooping • Enhanced Transmission Selection (ETS) Data Center Bridging Technology Overview The PowerConnect 8024/8024F switches support Data Center Bridging (DCB) features to increase the reliability of Ethernet-based networks in the data center. The PC81xx switches support PFC, ETS, and DCBX capability exchange, with the ability to autoconfigure from a peer switch. The PC80xx switches support FIP Snooping, DCBX capability exchanges and ETS proxy, and the ability to autoconfigure from a peer switch. The PC80xx also can be manually configured to support bandwidth sharing among traffic classes. The Ethernet enhancements that DCB provides are well suited for Fibre Channel over Ethernet (FCoE) environments and iSCSI applications. Table 29-1 provides a summary of the features this chapter describes. Table 29-1. Data Center Features Feature PFC Description Provides a way to distinguish which traffic on a physical link is paused when congestion occurs based on the priority of the traffic.
