na_dcb - manage Data Center Bridging (DCB) configuration
for DCB capable interfaces
dcb show [ interface [ pgid ] ]
dcb priority show [ interface [ 0...7 ] ]
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
group.
Flow control : The flow control is either enabled or
disabled on a specific priority.
- show
- 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.
priority show
Displays the dcb configuration indexed by the
priority 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, a priority value can be
specified. The valid priority value ranges
from 0 to 7.
