NAME

na_dcb - manage Data Center Bridging (DCB) configuration for DCB capable interfaces

SYNOPSIS

dcb show [ interface [ pgid ] ]

dcb priority show [ interface [ 0...7 ] ]

DESCRIPTION

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.

OPTIONS

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.

EXAMPLES

dcb show

dcb show e2a

dcb show e2a 1

dcb priority show
