DESCRIPTION

24       dcb apptrust is used to configure per-selector trust and trust order of
25       the Application Priority Table, see dcb-app(8) for details on how to
26       configure app table entries.
27
28       Selector trust can be used by the software stack, or drivers (most
29       likely the latter), when querying the APP table, to determine if an APP
30       entry should take effect, or not. Additionally, the order of the
31       trusted selectors will dictate which selector should take precedence,
32       in the case of multiple different APP table selectors being present.
33
34

COMMANDS

36       show   Display all trusted selectors.
37
38
39       set    Set new list of trusted selectors. Empty list is effectively the
40              same as removing trust entirely.

PARAMETERS

44       The following describes only the write direction, i.e. as used with the
45       set command. For the show command, the parameter name is to be used as
46       a simple keyword without further arguments. This instructs the tool to
47       show the values of a given parameter.
48
49
50       order SEL-LIST
51              SEL-LIST is a space-separated list of selector names. Possible
52              selector values are: ethtype, stream-port, dgram-port, port,
53              dscp, and pcp

EXAMPLE & USAGE

58       Set trust order to: dscp, pcp for eth0:
59
60       # dcb apptrust set dev eth0 order dscp pcp
61
62       Set trust order to: port (stream or dgram), pcp, ethtype for eth1:
63
64       # dcb apptrust set dev eth1 order port pcp ethtype
65
66       Show what was set:
67
68
69       # dcb apptrust show dev eth0
70       order: port pcp ethtype
