DCB-MAXRATE(8)                       Linux                      DCB-MAXRATE(8)
NAME
       dcb-maxrate  - show / manipulate port maxrate settings of the DCB (Data
       Center Bridging) subsystem
SYNOPSIS
       dcb [ OPTIONS ] maxrate { COMMAND | help }
       dcb maxrate show dev DEV [ tc-maxrate ]
       dcb maxrate set dev DEV [ tc-maxrate RATE-MAP ]
       RATE-MAP := [ RATE-MAP ] RATE-MAPPING
       RATE-MAPPING := { TC | all }:RATE
       TC := { 0 .. 7 }
       RATE := { INTEGER[bit] | INTEGERKbit | INTEGERMib | ... }
DESCRIPTION
       dcb maxrate is used to configure and inspect maximum rate at which
       traffic is allowed to egress from a given traffic class.
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 instructs the tool to
       show the value of a given parameter. When no parameters are given, the
       tool shows the complete maxrate configuration.
       tc-maxrate RATE-MAP
              RATE-MAP uses the array parameter syntax, see dcb(8) for
              details. Keys are TC indices, values are traffic rates in bits
              per second.  The rates can use the notation documented in sec-
              tion PARAMETERS at tc(8).  Note that under that notation, "bit"
              stands for bits per second whereas "b" stands for bytes per sec-
              ond. When showing, the command line option -i toggles between
              using decadic and ISO/IEC prefixes.
EXAMPLE & USAGE
       Set rates of all traffic classes to 25Gbps, except for TC 6, which will
       have the rate of 100Gbps:
       # dcb maxrate set dev eth0 tc-maxrate all:25Gbit 6:100Gbit
       Show what was set:
       # dcb maxrate show dev eth0
       tc-maxrate 0:25Gbit 1:25Gbit 2:25Gbit 3:25Gbit 4:25Gbit 5:25Gbit
       6:100Gbit 7:25Gbit
EXIT STATUS
       Exit status is 0 if command was successful or a positive integer upon
       failure.
