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 Operation with DCBx (ETS)
Data Center Bridging Technology Overview
The PowerConnect M8024-k switches support Data Center Bridging (DCB)
features to increase the reliability of Ethernet-based networks in the data
center.
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.
NOTE: Data Center features are supported only on the PCM8024-k for
PowerConnect modular switches. The PCM6220, PCM6348, and PCM8024
switches do not support the features in this chapter.
