DCB-APPTRUST(8)                   Linux                  DCB-APPTRUST(8)

NAME         top

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

SYNOPSIS         top

       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         top

       dcb apptrust is used to configure per-selector trust and trust
       order of the Application Priority Table, 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         top

       show   Display all trusted selectors.

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

PARAMETERS         top

       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
       instructs 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         top

       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         top

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