NAME
       devlink - Devlink tool

SYNOPSIS
       devlink [ OPTIONS ] { dev|port|monitor|sb|resource|region|health|trap } { COMMAND | help }

       devlink [ -force ] -batch filename

OPTIONS
       -V, --Version
              Print the version of the devlink utility and exit.

       -b, -batch <FILENAME>
              Read  commands  from  provided file or standard input and invoke them.  First failure will cause termination of de‐
              vlink.

       -force Don't terminate devlink on errors in batch mode.  If there were any errors during execution of  the  commands,  the
              application return code will be non zero.

       -n, --no-nice-names
              Turn off printing out nice names, for example netdevice ifnames instead of devlink port identification.

       -j, --json
              Generate JSON output.

       -p, --pretty
              When combined with -j generate a pretty JSON output.

       -v, --verbose
              Turn on verbose output.

       -s, --statistics
              Output statistics.

       -N, -Netns <NETNSNAME>
              Switches to the specified network namespace.

       -i, --iec
              Print human readable rates in IEC units (e.g. 1Ki = 1024).

       -x, --hex
              Print dump numbers in hexadecimal format.

   OBJECT
       dev    - devlink device.

       port   - devlink port.

       monitor
              - watch for netlink messages.

       sb     - devlink shared buffer configuration.

       resource
              - devlink device resource configuration.

       region - devlink address region access

       health - devlink reporting and recovery

       trap   - devlink trap configuration

   COMMAND
       Specifies  the action to perform on the object.  The set of possible actions depends on the object type.  As a rule, it is
       possible to show (or list ) objects, but some objects do not allow all of these operations or have  some  additional  com‐
       mands.  The help command is available for all objects. It prints out a list of available commands and argument syntax con‐
       ventions.

       If no command is given, some default command is assumed.  Usually it is list or, if the objects of this  class  cannot  be
       listed, help.

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