NAME
       dcb-apptrust  - show / configure per-selector trust and trust order of the application priority table
       of the DCB (Data Center Bridging) subsystem.

SYNOPSIS
       dcb [ OPTIONS ] apptrust { COMMAND | help }

       dcb apptrust show dev DEV [ order ]

       dcb apptrust set dev DEV [ order SEL-LIST ]

       SEL-LIST := [ SEL-LIST ] SEL

       SEL := { ethtype | stream-port | dgram-port | port | dscp | pcp }

DESCRIPTION
       dcb apptrust is used to configure per-selector trust and trust order of the Application Priority Ta‐
       ble, see dcb-app(8) for details on how to configure app table entries.

       Selector trust can be used by the software stack, or drivers (most likely the latter), when querying
       the APP table, to determine if an APP entry should take effect, or not. Additionally, the order of
       the trusted selectors will dictate which selector should take precedence, in the case of multiple
       different APP table selectors being present.

COMMANDS
       show   Display all trusted selectors.

       set    Set new list of trusted selectors. Empty list is effectively the same as	removing  trust	 en‐
	      tirely.

PARAMETERS
       The  following  describes  only	the write direction, i.e. as used with the set command. For the show
       command, the parameter name is to be used as a simple keyword without  further  arguments.  This	 in‐
       structs the tool to show the values of a given parameter.

       order SEL-LIST
	      SEL-LIST	is  a space-separated list of selector names. Possible selector values are: ethtype,
	      stream-port, dgram-port, port, dscp, and pcp

EXAMPLE & USAGE
       Set trust order to: dscp, pcp for eth0:

       # dcb apptrust set dev eth0 order dscp pcp

       Set trust order to: port (stream or dgram), pcp, ethtype for eth1:

       # dcb apptrust set dev eth1 order port pcp ethtype

       Show what was set:

       # dcb apptrust show dev eth0
       order: port pcp ethtype

EXIT STATUS
       Exit status is 0 if command was successful or a positive integer upon failure.
