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 para‐
       meter 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 section  PARAMETERS  at  tc(8).	Note
	      that under that notation, "bit" stands for bits per second whereas "b" stands for bytes per second. When show‐
	      ing, 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.
