Data center bridging (DCB) refers to enhancements to Ethernet
local area networks (LAN) for use in data center
environments. DCB adds extensions to Link Layer Discovery
Protocol (LLDP) to provide higher granularity in control
of bandwidth allocation and to ensure it is used more
effectively. Beyond the benefits to traditional application
traffic, DCB makes Ethernet a viable transport for
storage and server cluster traffic in data center environments.
The dcb command is used to manage the DCB configuration
for DCB capable adapters installed on a controller. The
DCB configuration includes:
PGID : Priority Group ID. A priority group is group of
priorities bound together by management for the purpose of
bandwidth allocation. All priorities in a single group are
expected to have similar traffic handling requirements
(latency, frame loss and so on).
Bandwidth : Bandwidth assigned to a priority group.
Application : Application assigned to a specified priority
Flow control : The flow control is either enabled or disabled
on a specific priority.
- Displays the dcb configuration indexed by pgid
for the specified DCB capable interface or for
all DCB capable interfaces if no interface is
specified. If users are interested in the DCB
configuration on a particular priority group,
the pgid argument can be used.
Displays the dcb configuration indexed by the
priority for the specified DCB capable inter_face
or for all DCB capable interfaces if no
interface is specified. If users are interested
in the DCB configuration on a particular
priority, a priority value can be specified.
The valid priority value ranges from 0 to 7.
